Has anyone here installed the ROTORA 12/4 piston brake kit on their M5.
Or has anyone installed an aftermarket brake kit? Any further comments on this? I asked this question before and most people commented that M5 brakes do just fine on the streets. And even for race track, they are also excellent.
Can the stopping power of the aftermarket brake kit be really felt as compared to the stock in order to justify it's cost?
