Hey whatsup... heres the story ya'll I've got a 1990 bottom of the line Camry

hehe... no power steerin', no a/c.
I got enuff dough to get a new car but i just got my licence and i dont wanna crash a new Xpensive car.
So i was just thinkin of spiffin up this camry abit...
- I was thinkin 17' Lenso Concept Five rims, now cuz its not power steerin i was wondering wat MAX tire width i could get without it being to hard to steer?
- I was also gonna lower it abit, but i dunno nothing about that so any advice ya'll can give me'll b TOPS
Sorry ya'll... almost dun

- Also i was gonna get a straight through Xhaust dun... i know it'll sound alot better but do ya'll know wat kind of performance increase i'll get?
(btw wats the MAX speed supposed to be for this model... cuz i cant seem to get it past 130kph)
If u's could give me sum help here that would be kewl... And if u's think of ne thing else i could to supe up my CAMRy just tell us... THANX
