Questions on down grading brakes 4 piston to 2 piston.
Will I need to buy smaller rotors? I have a 5 lug 4 piston caliper setup currently. I'd like to swap to the smaller 2 piston calipers so I can fit skinny race rims up front. What all do I need to do this properly?
Thanks....

I presume for drag racing, he wont have to worry about brake fade/heat issues like autocrossers would.
As long as you have the correct BIGGER single piston calipers you will be good * base model S4 single piston will be smaller then the 4 piston calipers etc* .. just make sure you have the single piston brake lines too because the 4 piston calipers have a hardline on them and the singles do not. then should be good to go

I use FD 4 piston calipers and run a 8 pound 15x4 skinny. They need some spacers and didn't require any grinding. When I'm driving around town and at the autocross I don't have crappy brakes either.
