Re: Post Car Classing Help Questions Here!

Hi guys, i have a 2013 370z Nismo, which i know is in the STU class, but i do have Cold Air Intakes, ArT Test Pipes and a Catback Exhaust System. I am also upgrading rear diff bushing to stiffer ones, and may tune my car soon. Will that kick me into a different category?
