Schroth Profi 2x2 Porsche GT3/GT4 6 Point Racing Harness

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 Profi 2x2 GT3 features Frontal Head Restraint (FHR or HANS) specific 2” shoulder belts, 2" Pull Down Profi Lap Belts with attachments for Porsche's Light Weight Carbon Bucket seats sewn in. A T-bar adjustable sub strap is standard, and shoulder and sub strap 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. 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.

Comes with Porsche-specific attachments for the Lap belts and Snap-In attachments at Sub points. The Shoulders come ready to be wrapped around a roll-bar. Bolt in attachments can be purchased separately for shoulders and sub strap. Available in black and red.
