This harness fits the Porsche GT3 Cup 996/997 chassis. If you have a Porsche 996 GT3 or 997 GT3 that started life as a race car with a cage, air-jacks and no carpet, this is your belt. Another popular fitment is when you have a Porsche 981/991 GT3 GT4 Carbon Fiber one piece leather seat that is not FIA approved and has a three point belt attached to it.

This harness fits the Porsche GT3 Cup 996/997 chassis. If you have a Porsche 996 GT3 or 997 GT3 that started life as a race car with a cage, air-jacks and no carpet, this is your belt. Another popular fitment is when you have a Porsche 981/991 GT3 GT4 Carbon Fiber one piece leather seat that is not FIA approved and has a three point belt attached to it. This is also the easiest and most popular belt when retrofitting a Porsche street car that is turning into a race car.
Porsche GT3 Cup Cars Come With Schroth Belts Direct From The Factory. If you need to replace them because of an incident, updating or if you're putting the factory GT3 seat setup into another car, you'll want these Schroth Profi Porsche 996/997 2x2 belts.
Schroth Porsche 996/997 GT3 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 996/997 GT3 2x2 Harness Waist Belts:
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 996/997 GT3 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 996/997 GT3 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 996/997 GT3 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.
