I need to know if the "Wilwood 11.75" Race Brake Kit" from Webb Motorsports will fit under the Kosei K1 racing 15x7 wheels. Wanted to make sure before ordering up my new wheels.

I'd email Randy. I believe he runs Kosei's on his car too. Even if he doesn't, though...he should know since he sells them.

 

It should barely fit. Most likely you'd need a thin 5mm spacer for the fronts.
Most of the larger 16" and 17" stock rims will fit without a spacer.
The SSR Comp 15x7" rims need a 5mm spacer because it's just barely enough room.

Talk to Randy. He runs Kosei K1 Racers but in 17x7.5" size.

 

Where would one go about getting these 5mm spacers?

 

can't tell you about the kosei but i just installed this race kiit with SSR 15 X 7 Comps. The rim fit without hitting while car was on stands but there was no space at all between the caliper- it wasn't even 1/32". I got 5mm spacers and they work fine with no issue (probably could have gotten by with 3mm). Got the spacers from Randy Webb who got them shipped from H&R. You'll also need 5mm longer lugs or studs.
