Dave's Evo X Build/The Life of Dave blog

[Kracka]

Changing out the brakes is a really dangerous idea considering you're still wanting it to be a street car plus have the possibility of taking it on the road course sometime. You already have some nice lightweight rotors...leave well enough alone. If you want to shave weight, a lower weight wheel and tire combo will be more beneficial anyway.

Mark Berry did the small lightweight drag rotors on his 2200 lb. Evo VIII and he said they're fine for autocross due to his car being so light, but said he'd never consider taking them on the road coarse or even a fast/spirited street cruise.
