I mostly run STX. I just have some basic mods, intake, header, exhaust, underdrive pulley, safc tune, coilovers, rear sway bar, and various wheels and tires. This past season I ran 215/45/16 azenis rt615s on 16x7.5 rota wheels (the blackish wheels in the pics). Next season it will most likely be turbocharged and Ill be moving to Street Mod, where Ill be competeing with 450+whp EVOs on hoosiers, so this was the last season I was able to be competetive, for a few years at least.
