I have a 2006 GT. During the summer, I run Toxic 20" Defiance rims, but since I live in Missouri, I need to switch back to my stock polished 18" Bullit wheels for winter. Here's my problem, I'd really like to get some bigger brakes all around, like the 14" Brembos off a GT500, but apparently nothing works with my stock wheels. Can anybody give me some advice on what to do, like kits that do work, or if spacers fix the problem or anything that you've done that works well. Thanks for your help!!!
