Not for TCS as much in this car (but probably still in very low grip situations), more for VSC on the RS. It'll use all the brakes to try to stop something bad from happening.I'm not sure if they are the same as the ST on the rear, the pics of them just look very standard OEM with the sliding caliper so I assumed (probably wrongfully) that they were ST gear. Maybe a different sized piston in the caliper? All speculation at this point I guess! Also re: braking as part of traction/stability control, does the FoRS utilise braking to achieve stability or traction? I was under the impression it was all done with the clutch system.
