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 GT3 Enduro 2x2 6 Point Racing Harness 2028 EXPIRY FITS*   Porsche 991 GT3/GT3RS Porsche 981/718 GT4 Porsche 918   FAST DRIVER CHANGES Fitting the Porsche GT3 with Porsche's carbon bucket seats - 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 FOR 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. ENDUROS 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 aluminium 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 Porsche GT3 Enduro 2x2 Harness Shoulder Belts:This is the first thing a 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" width 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 Porsche GT3 Enduro 2x2 Harness 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.Schroth Porsche GT3 Enduro 2x2 Harness Waist Belt Chassis Fittings: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 here 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.

We love this feature on all Schroth belts. Schroth Flexi 2x2 6 Point Hans Harness Waist Belts: At first look, you would say that the waist belts are the same as the old Profi II. If you did say that, you are correct. Schroth maintained the great flexibility of the Profi II waist belts to ensure they could be installed in a pull-up or pull-down configuration. You simply unwrap and remove the chassis snap end and cam-lock end and swap them around. Re-wrap like you just unwrapped and you now have a pull-up harness. Race prep shops love this feature as one part number can be configured for every driver preference.

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.

The Safe, Street Legal 4 Point Harness The Profi II ASM FE is essentially the same as the Profi II ASM, except it features a Push-Button cam lock. The red push button that says "Press" is necessary to retain street legality and so an EMT who shows up at an accident scene will know how to release your restraint. The FE version also features sewn in, bendable bolt-in tabs for the lap belt attachments, for use in applications where space is limited. It's designed to be used as a four point system, perfect for use in Driver Education cars or any other application where stock seats are retained. (A seat that was not originally designed for a sub strap should never be modified to accept one.) The Profi II ASM incorporates Schroth's legendary ASM (Anti Sub Marining) technology that is the only thing like it on the market. ASM is an extra fold of material sewn into the right shoulder belt that elongates at a different rate than the outboard belt. This allows your upper torso to twist slightly. On the rebound phase, your torso is planted firmly back in the seat rather than allowed to slide under the lap belt. You can add a single or dual sub strap to make this belt into a 5 point or 6 point at any time. Schroth tested this harness with a HANS device and the results were great. You can use a 4 point ASM Harness with any HANS device. The lap belts provided with this harness are only available with bolt-in hardware (it's sewn in) as they are most commonly needed in setups requiring street legality. If you need a different setup, please call 888-748-7223. The shoulder straps come with wrapped-in B23C bolt-in brackets that can be easily removed to wrap around a roll bar or harness bar. See the Schroth Harness Installation Checklist here.

Schroth Quick-Fit 4-Point Harness The Quick Fit Harness from Schroth is an excellent harness solution for people who have dual duty cars (track and street). Not many of us have the means to support a full time track vehicle as well as a street car, and still more of us like driving track-prepared cars on the street. The ultimate harness solution includes fixed-back Kevlar seats, a gazillion point welded roll-cage and a HANS device. None of us are going to (nor do we recommend) do this in our street cars. What's the next best thing? The Schroth Quick Fit Harness. It anchors to factory points, which means you don't have to worry about it ripping out of the sheet metal. The factory points are load tested to withstand a 3,000-pound force for 6 seconds. It has ASM technology that keeps the lap belt low and your rear end firmly planted in the seat. You don't want the lap belt riding up and squeezing your stomach and intestines. A Schroth belt is designed not to. The Quick Fit Belts also take advantage of the factory seat belt pre-tensioner, a device that tightens the belt 1-2 inches in the event of an accident. The Airbags will deploy as the engineers of the system intended for someone buckled in. With any other harness, the car wouldn't detect that someone was buckled in, so the airbags would deploy faster and harder. They also come completely out of the car, giving you full use of your street car for carrying people or cargo. That is what it's for, isn't it? If you have any questions regarding a harness solution for you, please contact us. Please note: These harnesses are designed to be used in stock seats that have passed a seat back strength test. Quick Fit harnesses are not approved for use with any fixed back or aftermarket seats with the following exceptions: The Cobra Nogaro and Recaro Pole Position ABE are approved for use with QuickFIt harnesses in already approved vehicles. This harness is not compatible with HANS or any other head and neck restraint devices. If you plan on using a HANS, the Quick Fit Pro version is compatible.

Schroth Quick-Fit Pro 4 Point Harness For the first time, a four-point harness has been designed for use with a HANS device with stock seats! Perfect for HPDE, Track Day, and Driving School cars, the Schroth Quick-Fit Pro 4 Point Harness provides your customers a safer, more authentic driving experience by driving with a HANS device. With this harness, you don't have to spend thousands of dollars on a roll bar, new seats, and six-point harnesses to run safely on track! Coupled with a vehicle’s existing safety systems, the Schroth Quick-Fit Pro 4 Point Harness is designed to maximize effectiveness of your HANS device. Traditional four-point harnesses are sewn to lap belts, and don’t join at the center cam lock. This creates a six- to eight-inch gap. The Schroth Quick-Fit Pro 4 Point Harness answers this problem by allowing each shoulder belt to angle towards the cam lock, integrating with the HANS device. The Schroth Quick-Fit Pro 4 Point Harness works in conjunction with your car’s seat belt pre-tensioner and airbag for additional peace of mind. The Quick Fit Pro clicks into the car’s female seat belt receptacle, notifying the car’s airbag computer that the seat is in use and the driver is restrained. The pre-tensioner is also activated. This device ignites a pyrotechnic charge if an accident happens, tightening the lap belt and holding your driver in snugly. The Schroth Quick-Fit Pro 4 Point Harness is meant to be used with stock seats that have passed a seat-back strength test.
