Bolt-In Window Net Kit with Schroth Net Our Bolt-In Window Net Kit includes a Schroth ribbon net and is designed to make window net installation fast and easy using normal hand tools. Available in two sizes, the small is 16.5" wide that is perfect for Spec Miata and Honda S2000's while the large 20" wide version fits BMW Spec E46, Trans-Am TA2 and other larger door openings. Installation parts include both weld and clamp on options, with all required hardware included. The Window Net Hardware Kit was designed to revolutionizes window net installation, while also incorporating an easy to operate design. Available in both small and large sizes, this Hardware Kit can be purchased as a stand-alone item, or a complete kit with Schroth Racing Window Net. Drivers wishing to use their own net will be pleased to learn this kit can be used with many competitors’ nets, including TEAMTECH window nets.  Small kits are designed to work with window nets up to 16.5" wide, and the large kits are work with most 20" wide nets.  Installation methods include both weld and clamp on options, with the required hardware included for each application. With both versions of the hardware kit, the upper bar is secured to the cage using mounting tabs which can be welded or clamped. Using a spring-loaded mechanism, the upper bar easily slides in and out of the tab. The two kits differ based on how the lower bar attaches the vehicle. Bolt-in Window Net Kit GT Version The GT version secures the lower bar to the roll cage using 1-meter-long nylon mounting straps. The adjustability of the nylon straps creates the most versatile mounting solution, perfect for road and GT cars. Included in the Bolt-in Window Net Kit:  (1) - Long Mounting Tab (1) - Short Mounting tab (4) - Mounting band clamps (2) - Collar Clamps (1) - Clamp Handle w/#6-32x38 screw (1) - Spring Loaded bar (Upper) (1) - Lower Bar (2) - 1 Meter long Mounting Strap (1” wide) (4) - 3 bar side (1” wide) Upper Mount BarThe upper bar is secured to the cage using your choice of the included clamp-on bracket or welded tabs. The round upper bar uses a spring-loaded mechanism that fits perfectly between the two mount brackets to provide an easy to install net kit that keeps debris out and hands and arms in. Lower Mount BarTo secure the bottom bar and adjust window net tension, two nylon mounting straps with adjustable lock bars connect the bottom round bar to your roll cage. 

Schroth 2" Harness Bar Slide This Schroth 2" bar slide is designed for use with 2" webbing. It is found on almost all Schroth harnesses because it has virtually no micro-slip under significant load. It can be used to wrap 2" webbing to a harness bar, or to wrap an end fitting into a 2" strap. This bar uses the more complex two-bar wrapping technique.

Schroth B23A Bendable Harness Snap End Kit Schroth B23A harness ends are bendable and make racing harnesses easier where there is very little clearance. The Schroth B23A bendable snap-on harness adapter lets you bolt one end to the chassis, bend it to the needed shape, and attach your harness snap end. Schroth B23A Bendable Harness Snap End Kit Details: Manufacturer: Schroth Manufacturer part number: B23A Manufacturer alternate part number: SR 01324 Bendable Fittings: Yes (2) Bolts: Yes (2) 7/16-24 Wavy Washers: Yes (2) Combination Washers: Yes (2) The B23A End Fitting Kit is a set of bolt in brackets that are usually sewn into 2" Lap belts. Schroth slang calls it a "Rallye End" kit because it usually comes on the street legal Rallye style belts. Like the 01323 kit, it is designed to be bent. These pieces are commonly used in Porsche applications where space for an Eye bolt is insufficient. This bracket can be bolted to the car, then bent so that a Snap-In bracket can be used to fix the harness to the bracket. We use Schroth B23A brackets in many applications where stock mounting locations do not leave sufficient space, or if the thread pitch is different from the eye bolts. If you have a Miata, S2000 or are putting a large/very large seat in a full interior car this is the harness mount kit you want.

Schroth Clubman 2x2 6 Point Racing Harness Schroth's Clubman has one aim: to provide a superior harness for people needing a lower-cost belt. The Clubman features Frontal Head Restraint (FHR) specific 2” shoulder belts, 2" Clubman pull up lap belts, and a T-bar non adjustable sub strap. Shoulders and sub strap hardware is wrapped in. The FHR specific shoulder belts are designed to make FHR use safer and more comfortable. The full 2" shoulder webbing fits perfecting on a FHR device, creating optimal force distribution on the surface of the device. ADJUSTERS AND OPTIONS The adjusters on the Clubman belt are heavier and not as easy to use. They are, however, cheaper and bring down the overall cost of the harness. In addition the sub strap does not have adjusters and the lap hardware is not interchangeable. Only available with snap-in, pull-up lap belts. Laps are not reversible like they are on the Flexi 2x2. FEATURES: 2” shoulder belts 2” Profi pull-up lap belts with sewn-in snap-in hardware T-bar sub non-adjustable strap Rotary cam lock

Schroth Porsche GT2/GT3/GT4 Enduro 2x2 6 Point Racing Harness THIS HARNESS FITS THE FOLLOWING VEHICLES: Porsche 996 997 991 992 GT2/GT2RS/GT3/GT3RS Porsche 981/718 GT4/GT4RS Porsche 918 DESIGNED FOR THE FASTEST DRIVER CHANGES Comes in black and red with 2" shoulder and 2" waist/sub belts. The Schroth Porsche GT3 Enduro 2x2 Harness takes the best features of the best-selling Enduro belt and adds a few improvements. Save time in driver changes with the Schroth Enduro belt with "ZIP Adjusters" that allow for exceptional ease of adjustment (tightening) and release for faster and smoother driver changes. Note: This harness is designed for street cars with Porsche's factory One-Piece Carbon Bucket seats. If you are in a GT3 Cup Car or have a different fixed-back race seat, a standard Enduro will be better suited for your vehicle. Endurance racing drivers need to be able to get in and out of the car quickly and easily during a race. The Schroth Porsche GT3 Enduro 6 Point Racing Harness uses the newest, most innovative technology available to ensure ease of use during quick driver changes in the most arduous conditions. The Schroth Enduro 6 Point Racing Harness is considered the fastest, easiest harness to use among many drivers. All while maintaining the superior quality and durability for which Schroth is famous. The Schroth Porsche GT3 Enduro 2x2 Racing Harness has been tested for quality and ease of use in the WEC endurance series and in 24-hour races at legendary venues like Germany’s Nürburgring Nordschleife. The Schroth Enduro 6 Point Harness is at the top of its game, constructed for racers who need superior driver restraint technology. The new design of the ZIP Adjuster is integrated into the lap belt buckle attachments, making the position of the adjusters ideal for quick, precise tightening. This design -- featuring clearly-marked belt release straps, extra large, easy-to-see, yellow hand loops on the lap belts -- also ensures efficient, smooth releases and tightenings for quicker, easier driver changes. The Schroth Enduro 6 Point Racing Harness also has these ZIP Adjusters on the shoulder belts. MADE ESPECIALLY FOR YOUR PORSCHE Schroth ups the ante with its Porsche GT3 Enduro 2x2, with sewn-in lap belt attachments specifically for Porsche's OEM carbon bucket seats. The lap belts bolt in simply, without any drilling or other modifications for a factory-installed look. Attachment of the shoulder belts requires the use of a roll bar or harness bar, and the sub straps must be mounted to a sub strap bar beneath the seat. BUILT FOR ENDURANCE RACING AND BEYOND The Schroth Enduro 2x2 6 Point Harness is a first choice for endurance racing teams, racing schools, and corporate ride-along venues where transitioning in and out of the race car quickly while maintaining top safety and durability is a winning combination. The Schroth Enduro 2X2 6 point race belt is Schroth's top-of-the-line racing harness for Endurance racing. The Schroth Enduro belt features the widely praised ZIP Adjusters integrated into the lap belt buckle attachments to optimize the position of the adjusters for perfect and fast adjustment. The rotational design of the ZIP Adjusters allows for exceptional ease of adjustment (tightening) and release for faster and smoother driver changes. The Schroth Enduro 2X2 6 point harness is designed specifically for when fast driver changes are needed in endurance racing. The lap belt straps have large, easy to grab adjuster loops for the easiest adjustment. Newly designed compact aluminum rotary buckle features a quicker, more positive “click” and an ergonomic release lever. One of the main features of the Enduro 2X2 belt systems is the 2" (50mm) lap belt for added safety over 3" designs. A 2" belt rides within the crest of the human pelvis where a 3" belt would rest on the edges. This allows you to get the belt up to an inch and a half tighter. That means the lap belt will be working earlier in an accident because it gets loaded faster. It's also more comfortable and easier to adjust because there's less friction through the adjuster. SCHROTH ENDURO 2X2 PORSCHE GT3 SHOULDER BELTS This is the first thing a Schroth Profi II racer is going to notice - the shoulder belts. Instead of going from 2" from the adjuster up and 3" from the adjuster down, the Enduro 2x2 has a full length 2" wide shoulder belt. At first, being a racer who does not like change, I wanted my same 3/2" shoulder belt. Upon sitting in a race seat and mounting the harness, Schroth actually improved on something I though did not need improvement. They are easy to lay up on my HANS device, are a little lighter, and the new small adjusters are nice. Actually, really nice. I like the new lightweight adjusters better than my Profi II. This is a nice upgrade I did not know needed upgrading. The shoulder belt camlock ends are still keyed (angled) for individual left and right to keep driver comfort at a maximum, no matter how large or small the driver is. We love this feature on all Schroth belts. SCHROTH ENDURO 2X2 PORSCHE GT3 WAIST BELTS At first look, you appreciate the technology that Schroth puts into their ZIP adjusters that are part of the slip-in end of the waist belt. Spring loaded, but easy to release. German perfection is found in the Schroth Enduro series harness sets. Featuring a precise sewn-in waist belt to chassis fitting, the Schroth Porsche waist belt fits perfect. Everything is in the perfect position and legal for all competition you may see, even the 24 Hours of LeMans. We sew the Schroth B43A end on both of the waist belts so installation is like your super car came out of Stuttgart. Schroth Porsche GT3 Enduro 2x2 Harness Waist Belts 2" vs 3". All Schroth Enduro Belts are 2" (50mm) wide and are more effective that the 3" (75mm) waist belt. Why is 2" webbing more effective than 3" webbing? Let's start looking at the shape of our human body. The Iliac Crest (IC) is the part of the pelvic bone that sticks out above the hips. 2" webbing fits entirely within the recession created by the Iliac Crest where 3" webbing rides over the top of the Iliac Crest. Because of this, the 3" webbing has less contact area by percentage than the 2" webbing which will cause more bruising during an impact where the belt is making contact with the pelvic bone. Since the 2" webbing rides inside the Iliac Crest, it can be worn as much as 1" to 1.5" tighter and at the same time is more comfortable for the driver. Since the 2" webbing fits well within the Iliac Crest of the pelvis, it is less likely to slide up above the crest and cause submarining, a condition where the body slides down below the lap belt possibly causing internal organ damage.Research shows that the faster the pelvis is captured, the lower the resultant loads on the chest, head, and neck. There is no difference in the strength of the 2" webbing vs the 3" webbing. All webbing - 2" or 3" - must meet the same FIA homolgation test loads.There is an additional benefit of the 2" lap belts. The required force to properly and tightly adjust the belts in the car is much easier than with 3" belts. We at DiscoveryParts love and prefer the Schroth 2" waist belt system. Schroth Porsche GT3 Enduro 2x2 Harness Camlock: different or the same? The buckle looks like our old reliable Schroth Profi cam lock in non-glare matte black, and looks and feels the same externally. The only upgrade is a different amount of force required to turn the buckle. It is solidly positioned and has a very sharp snap when releasing. Nothing too drastic, if you start turning the camlock (in either direction) it just is tight, tight, tight, and boom - released. Actually there is no boom, it just releases cleanly. Schroth Porsche GT3 Enduro 2x2 Harness Sub Belt: safety is #1 with Schroth and comfort is elevated beyond any other harness competitor. Going back to safety, the buckle position is not just important, but paramount. For the loading of the belts to be properly spread over your pelvis, Iliac crest, and upper torso, we need the buckle to be positioned correctly on the driver. To help position the belt easily the first time and quickly fine-tune the position for a multiple driver car, Schroth added two adjusters for you. Sub-belt install time of a Schroth harness is 70% less than competitor harness sets.

Schroth Flexi 2x2 6 Point Racing Harness The Schroth Flexi 2x2 six-point racing harness replaces their most popular harness, the Profi II 6-H. Like its predecessor, the Flexi 2x2 is the benchmark for professional racing.It features HNR (head and neck restraint) specific 2” shoulder belts, 2" Flexi lap belts, and a T-bar adjustable sub-belt. The HNR-specific shoulder belts are designed to make HNR use safer and more comfortable. The full 2" shoulder webbing fits perfectly on all HNR devices, creating optimal force distribution on the surface of the device.What makes Flexi harnesses different from other harnesses in the Schroth line-up is the reversible Flexi lap belts; these lap belts can be changed from a pull-up to pull-down configuration by simply re-wrapping the hardware. This allows you to set the belt up just the way you want it for your specific situation. It also allows for bolt-in brackets to be wrapped in for the lap belts if needed. The Flexi 2x2 comes with snap-in attachments at the lap belt and sub belt attachment points. The shoulder belts are ready to be wrapped around a roll bar or roll cage. Additional snap- or bolt-in attachments can be purchased separately. Available in Black, Red, Blue or Yellow. See Schroth Harness Installation documentation here. FEATURES: FIA 8853-2016 homologated.

Schroth Flexi 2x2 Porsche GT2/GT3/GT4 Racing Harness Porsche GT3 Cup Cars come with Schroth belts direct from the factory. If you're putting harnesses in your Porsche GT2, GT2RS, GT3, GT3RS, GT4RS or GT4 with the Lightweight Bucket (LWB) seat setup, you'll want these belts! The Flexi 2x2 Porsche features 2” shoulder belts ideal for Frontal Head Restraint (FHR or HANS) devices. It has 2" pull-down Profi lap belts with sewn-in anchors specifically made for Porsche's carbon fiber Lightweight Bucket ("LWB") seats. A T-bar adjustable sub-strap is standard, and shoulder- and sub-strap attachment hardware is wrapped in. The FHR/HANS specific shoulder belts are designed to make the driver safer and more comfortable. The full 2" shoulder webbing fits perfectly on a FHR or HANS device, creating optimal force distribution on the surface of the device. The main impetus behind the 2" lap belt is added safety. A 2" belt rides within the crest of the human pelvis, where a 3" belt would rest on the edges. This allows you to get the belt up to an inch-and-a-half tighter, so the lap belt will work earlier in an accident because it gets loaded faster. It's also more comfortable and easier to adjust as there's less friction through the adjuster. Comes with Porsche-specific attachments for the lap belts and snap-in attachments at sub-strap points. The shoulders come ready to be wrapped around a roll bar or roll cage. Bolt-in attachments can be purchased separately for shoulder- and sub-straps. Available in Black, Blue, Red, silver, or Yellow. If you drive a GT3 Cup car or are driving a Porsche with a fixed-back racing seat, a standard non-Porsche harness such as the Enduro 2x2 or Flexi 2x2 would be better suited for your vehicle.

This harness comes with specific lap-belt brackets that don't require any drilling for installation, as they attach to the factory-engineered lap-belt mounting locations. A harness bar or roll bar are required for installation of the shoulder belts. Schroth's exclusive ASM (anti-submarine) technology on this four-point harness holds the driver pelvis snug in case of a crash, preventing submarining below the lap belt and sliding out of the seat. With this harness, there no need to install a sub-strap mounting bar under the seat, which is also very useful for Porsche passenger seats that don t have a pre-cut sub-strap slot. The Schroth Porsche GT3/GT4 Four-Point Harness has a street-legal FE Camlock that releases like a traditional seat belt -- just a push of the button!

Schroth Profi II ASM 4 Point Harness (Anti-Sub) The Schroth Profi II ASM 4 Point Harness (Anti-Sub) integrates Schroth unique ASM (Anti-SubMarining) technology in a four-point system. The ideal harness for stock seats, or seats not designed for a pass-through for a sub strap, that are used in Driver Education programs. Schroth ASM is an extra fold of material sewn into the inboard shoulder belt, elongating at a separate rate compared to the outboard belt. This allows two movements: the upper torso can twist slightly, and on the rebound phase, the torso is planted firmly back in the seat instead of sliding under the lap belt. The Schroth Profi II ASM 4 Point Harness is good for use with a HANS device or other Head and Neck Restraint (HNR). The ASM shoulder strap on the ASM is 3 width, which will work with any HNR. A dual or single strap can be added to convert this belt into a 5- or 6- point system. The shoulders are ready to wrap around a roll bar, and snap-in or bolt-in attachments can be purchased. The Schroth Profi II ASM 4 Point Harness also features a Flex Belt. Instead of being sewn into the harness, the cam latches and end fittings are wrapped, making configuration changes from a Pull-Up to a Pull-Down configuration quick and easy. In addition to helping you customize the use of your device for your particular situation, you can add bolt-in brackets to be wrapped in the lap belts. Snap-in brackets are standard on the lap belts. Choose from Black, Blue, or Red! Be sure to specify Driver or Passenger side as the construction is slightly different for each.

Schroth’s ASM is an extra fold of material sewn into the inboard shoulder belt, elongating at a separate rate compared to the outboard belt. This allows two movements: the upper torso can twist slightly, and on the rebound phase, the torso is planted firmly back in the seat instead of sliding under the lap belt. The Schroth Profi II ASM 4 Point Harness is good for use with a HANS device or other Head and Neck Restraint (HNR). The ASM shoulder strap on the ASM is 3” width, which will work with any HNR. A dual or single strap can be added to convert this belt into a 5- or 6- point system. The shoulders are ready to wrap around a roll bar, and snap-in or bolt-in attachments can be purchased. The Schroth Profi II ASM 4 Point Harness also features a “Flex Belt.” Instead of being sewn into the harness, the cam latches and end fittings are wrapped, making configuration changes from a Pull-Up to a Pull-Down configuration quick and easy. In addition to helping you customize the use of your device for your particular situation, you can add bolt-in brackets to be wrapped in the lap belts. Snap-in brackets are standard on the lap belts. Choose from Black, Blue, or Red! Be sure to specify Driver or Passenger side as the construction is slightly different for each. See Schroth Harness Installation Checklist Here
