Suspensions, For one Quikstep is right, itll be way more fun.

Also the V2 CAI is kinda a gimmick, I havent seen any REAL dynos (other then that from the company) that proves it gives that much more HP. And if you do go cai get a bypass valve, itll help you avoid hydrolock supposedly.

Also its hard to give you a quote on the suspensions, as there is so many companys and products to choose from. Just check around.
