Schroth Porsche GT3/GT4 Four-Point Harness (Anti-Sub) FITS PORSCHE CARBON SEATS ONLY* Porsche 996/997/991/992 GT3/GT3RS Porsche 981/718 GT4 Porsche 918 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’s pelvis snug in case of a crash, preventing “submarining” below the lap belt and sliding out of the seat. With this harness, there’s 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.

Schroth Flexi 2x2 Porsche GT3/GT4 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 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, Red, (Blue and Yellow by special order). 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. See Schroth's Harness Installation documentation here. FEATURES: FHR/HANS specific 2” shoulder belts. 2” Flexi pull-down lap belts with sewn-in Porsche hardware. T-bar adjustable sub-strap. Rotary cam lock. FIA 8853-2016 homologation.
