I don t think so...there is a badass C-Street-Prepared miata that has ultra-drilled rotors and weighs less than 2000 lbs..... he overheats rotors in a single 50second run (ridiculous)

why is the caliper still there? calipers are heavy
Colin Chapman once said:
Simplify, then add lightness
OP....i changed to lighter wheels (7lbs per corner) and immediately noticed quicker turn-in at corners........less weight is always a good thing on cars....less weight makes you faster everywhere but power only makes you quicker in a straight line.
That explains why a turbo miata with only 170-200whp will own left, right, up and down Corvettes on a road course.
Less weight also makes you use up less brake pad
