Schroth Racing Profi-II HANS Harness, Porsche GT3 Specific in Silver to Match Interior



Porsche GT3 Cup Cars come with Schroth belts direct from the factory. They are specific because of the lap belt attachment. They have a sewn-in bracket that fits perfectly on the factory mount. Standard belts require additional fabrication and a spacer to make them work. These are a bolt-in replacement which is much easier. The sub-straps have no adjusters to fit correctly in the vehicle, and the shoulder belts are shorter to reach the works cages with minimal excess.

• Shoulder: HANS Specific 2" tapered to 3" Shoulders
• Lap: Sewn-in B43A (GT3 Specific Hardware)
• Sub belts: LV11 with B14 Snap-in Bracket Wrapped-in
• Include hardware: 1 SG23 7/16" Eyebolt, 1 S3 Wavy Washer
• Available with Pull-Down lap belts only

BBi Sub-Belt Mount Porsche 991 GT3/ GT3RS / Cayman GT4



If you have the optional Sport Bucket seats and planning to install 6-point race harnesses, then you will need this bracket. Shown here as a pre-production example, this bracket bolts directly to the seat and keeps the harnesses at the proper 10-20° angle regardless of the seat position.

Features

• Provides mounting location for sub-belts at the proper 10-20° angle regardless of the seat position
• Precision CNC laser cut and bent from one piece high carbon steel for superior strength
• Stylish design with laser cut BBi logo and durable satin black Powdercoat finish
• Attaches to seat assembly using factory mounting points with all hardware included
• Compatible with Porsche 991 GT3 and 981 Cayman GT4 models equipped with Sport Bucket Seats
• Made in the USA
