FAST DRIVER CHANGES
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.

Schroth Porsche 991 GT3 Cup 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 Profi 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. 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 991 GT3 Cup 2x2 Harness Waist Belts:
Featuring a perfect sewn-in waist belt to chassis fitting, the Schroth Porsche waist belt fits perfectly. Everything is in the perfect position and legal for all competition you may see, even the 24 Hours of LeMans. Below is an image of your sewn-on waist belt to chassis fitting.
Schroth Porsche 991 GT3 Cup 2x2 Harness Waist Belts 2" vs 3":
All Schroth Flexi 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 991 GT3 Cup 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 991 GT3 Cup 2x2 Harness Sub-Belt:
Schroth Flexi 2x2 6 point harness has a dual sub strap system with T bar camlock connection. For comfort, Schroth uses a double dog leg fabric style that lets the flat part of the belt touch you, not the side. 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.

DESIGNED FOR YOUR PORSCHE
The Schroth Porsche GT3/GT4 four-point harness is designed specifically for the factory Porsche one-piece carbon seats. 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!
* Designed for Porsche OEM carbon bucket seats. This is not an FIA homologated competition restraint.

Porsche GT3 Cup Cars come with Schroth belts direct from the factory. If you're putting harnesses in your Porsche GT3, GT3RS, or GT4 with the Lightweight Bucket (LWB) seat setup, you'll want these belts!
The Flexi 2x2 GT3 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 and Red.
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.
