i have a 318is from the same year and it is a well balanced car, i'll out run a v6 mustang in the mountain roads where i live, none of my friends cars can match mine on the skidpad after i tied the frunt and rear struts and put the bilstein HD shocks on the car. Also with a new exhaust and better air intake plus minimal software tuning that beautifully engineered little 4-banger can scream. Remeber, this is no american peice you are driving, this is german beauty. To make it look cooler, rims and tires do a lot for a car, also might i suggest euro turn signals and tail lights, but if you put that altezza stuff on your car i will find you and smack you. plus maybe m-technics body peices. Check this place out they got a lot of stuff.
