rid yourself of the hideous grilles. drop it with some eibachs prokit only pay $230 at most, some people try to rip you off for even more than that. change the speakers because the stock stereo is gutless to say the least... and i don't mean wal-mart or autozone speakers. Rim and tire package will work well and be helpful with shifts of seasons... keep your stock rims and all season tires for fall and winter.. and break out the cool lightweight rims with summer tires for just that.. spring and summer. exhaust system is unnecessary as all you will notice is more noise unless you get it tuned... save your money when it comes to performance, it has enough to play with cars in it's class... tint the windows. keep the entire car clean, this includes the engine bay.. and that should be enough.
