I have an 01 CL-P with 18x7.5 axis mod with a +42 offset. Now i want to get a Big Brake Kit and i dont think it will fit with my rims and i think some ppl mentioned wheel spaces so my questions are

1. Do wheel spaces hinder performance in any way at all.

2. Do i really need the BBK cos i just got the legend calipers and also got Comptech brake lines that i was going to put on as soon as i got back to ATL.

PS, i drive 120mph daily to exercise my car.

Thanks
George
