I am wondering if there is any big brake kit conversion that I would be able to run my car without spacers.
I am using BBS 18's RS-GT model

 

I'm having a 13 inch kit, using Willwood calipers, made by Precision Brakes that fits my 18 inch rims without spacers. They provide a template in advance so you can actually test the fitment before buying the kit.

 

it depends on the wheel offset & brakes you want, brakezone will know..........
