If you're truly into Performance then pick-up a cheap pair of like 15" or 16" steelies to run on with some slicks if you're just going to drive on the track or something comparable to slicks. No body kit, lowering the car around 1.5" (too much won't be beneficial) and if you're just going on the track get the Kazuma exhaust, or get the TRD
exhaust which is street legal and gives the most gains other than the Kazuma. Then go for flywheel, pulley, your choice of air-Intake
type and remove what ever from your car you like.
