Bosch Motorsport M5 ABS Integration Kit for the Subaru WRX VA and STI, proposed platform
A Bosch Motorsport M5 ABS integration kit for the Subaru WRX VA and STI is a proposed platform at 909. It is not in development yet: this page measures demand, and the next development slots go to the platforms with the strongest registered interest.
Why the VA is on the list
The VA generation WRX and STI (2015 to 2021) picked up where the classics left off: circuit sprints, tarmac events and time attack fields carry plenty of them, with more weight and more speed than the cars our released WRX GD kit covers, and the same road calibration logic making the same conservative decisions. As with all Bosch Motorsport ABS, this is a sealed surface system for circuit and tarmac competition; it is not a gravel rally solution. The full comparison is in motorsport ABS vs factory ABS.
What a 909 integration kit would be
Across our released platforms, a 909 kit is the vehicle specific engineering around the Bosch Motorsport M5: wheel speed sensing designed for the hubs and axles the car actually runs, hydraulic unit mounting in a location we have tested, cabin hardware bracketed rather than improvised, and calibration support behind it. That is the standard any new platform gets developed to.
On every 909 kit, brake lines from the master cylinder to the hydraulic unit are made to suit the vehicle at install: 909 specifications call for Goodridge or Speedflow hardware.

Q: When could a kit exist?
A: It is not scheduled. If the platform earns a development slot we contact registered owners first, and development cars occasionally get early access.
Q: What would the kit include?
A: The same standard as our released kits: the Bosch Motorsport M5 with eleven selectable calibrations on a 12 position map switch, vehicle specific wheel speed sensing, tested hydraulic unit mounting, bracketed cabin hardware and calibration support.
Q: Can you ship overseas?
A: Yes. 909 vehicle specific kits ship worldwide. Contact us for freight to your country.
Q: Is the system validated for road use?
A: No, Bosch Motorsport ABS is for track usage only.
