I have to agree with evil my first track day i did with a Mitsubishi mirage with some run of the mill 15" aftermarket rims and some street tires i drove to the track removed EVERYTHING that was not bolted down including most of the stereo passenger seat and rear seat stuck some numbers on the doors and had a blast i then worried about a track car and am now looking at another one i can tell you now unless you strive to be a backyard mechanic or have some good friends that are mechanics it gets very expensive very fast but can be worth the time, bloodshed (from skinned knuckles) and money. IF you enjoy it.
