brakes are a relative thing......all brakes will have the ability to "lock" a given wheel on a given car...... the differences come in how well they can handle heat (think fade).... any "sports" cars brakes with proper pads and fluid will be fine on the track for DE purposes and can be for racing, with a good driver and near stock power....
Everyone is hung up on the fact that the M3 has simple sliding calipers & not a fancy fixed 4-6-8 piston brembo style brake....but the fact remains that the rotor design (two piece) is as good as they come.....14.2" doesn't hurt either.....
I haven't tracked my M3 yet...but will next month....and I intend to test the limits of the brakes....
