Bosch Motorsport ABS M5 Porsche 991 Cup is a plug and play ABS M5 installation kit developed and tested specifically for the Porsche 911 GT3 Cup (991 generation). The kit includes a vehicle-specific wiring harness matched to the 991 Cup body and a Porsche-specific mounting holder for the hydraulic unit. Compatible with both Generation 1 and Generation 2 of the 991 Cup car.
The kit uses the factory series wheel speed sensors already fitted to the 991 Cup — no replacement sensors are required. Brake pipe fittings and fuses are included. Developed and validated on circuit — tested at Spa-Francorchamps and Nordschleife.

12-Position Function Switch
The driver-accessible 12-position switch selects the ABS intervention map for current conditions — high grip dry, intermediate, or low grip wet surfaces. All positions use preset Bosch Motorsport ABS maps. No custom algorithm programming is required for the 991 Cup kit.
RaceABS Software and Configuration
Vehicle parameters are set using RaceABS software, available free of charge from Bosch Motorsport. The Bosch Motorsport MSA-BOX II USB interface is required for connection between laptop and ABS unit (sold separately).
Configurable parameters include vehicle weight, track width, wheel weights, wheel circumference, wheelbase, and wheel speed sensor increment count.
After every order, XTRA Motorsport support engineers contact the customer to confirm CAN bus speed and vehicle-specific installation requirements.
