Just got a beautiful 90 coupe (70K miles, ride control, six speed) last week. Spent a few hours changing oil/filter, brake fluid etc.. What is the best way to raise the back of the car with a floor jack? Autocrossing for the first time this weekend and want to check out the rear suspension etc. prior. I'll need a new exhaust system soon. Any recomendations. I would like something not to loud but with better than stock flow. Also, any suggestions on headers? The l98 could use some help in the power dept. so a three angle valve job and porting are on the list of future projects and I'll need headers to increase flow. Any suggestions are welcome.
