If you drive a 200SX, maybe, as they dont handle or stop very well. Doesnt work for anything though, a MkIII MR2 for instance - why would you want to do the handling and brakes first on one of them, they are perfectly good already.
Theres also the noise aspect that you get from exhaust, induction, decats - its a good thing but doesnt fit in any of the above categories.
Oh, and Abbey dont hold the fastest jap car in Europe at all, dont know where you got that one from. and the foreign language, and the bedroom cowboys, what actually are you on about?
