Yes, the car has 10,87" rotors. They work ok for the street, but it's a hobby, right! And after upgrading motor, driveline and suspention I don't think tossing a few bucks into better brakes with new disc's etc won't be a bad idea. And when already digging in it why not atleast put on bigger rotors and maybe shave off some weight with lighter calipers?
Besides- I think I have got some wrong info around how to find adapters for 11-3/4 discs. I need some info on how to measure a 11-3/4 adapter.
