I saw the setups on Fast-Brakes.com and they look like they might. Im just wondering how good of a setup can you get and still retain the stock 15"s

 

It might depend on what 15's you have, but yeah, Fast-brakes does make some kits that are supposed to fit under 15's. If your question is specific you could always call/ email them... if not I'm sure someone around knows.

 

I want to work on the Killer sleeper setup. I really want to put them under some wheels with Hub Caps

 

as long as they're kinda wide it prolly won't be a problem. But getting steelies that aren't wide is pointless to begin with (at least for any racing applications). If you're not gonna get the wide wheels it's pointless to get the big brakes because you won't be able to apply the stopping power to the ground. Just look around for some 15x7's or so that are steelies. I'm sure theyr'e out there, you just gotta find them

 

There are a lot of cars that are 4x100 you might be able to find a 7" steelie. Good luck.
Also, spacers will do you good.

 

im pretty sure the fastbrakes setup will work
