Hi all I recently purchased a 2011 3.8 R-spec specifically for track use. I am just wondering what the best bang for the buck track mods would be..I want to focus strictly on handling/braking. (It does have the brembos) NO engine mods. My budget is about 3-4K obviously tires are critical, is anyone running 18x9.5 wheels in the front and 18x10.5 rear? Thanks!
