I have a '92. I have two friends that have pretty fast cavvy's (one's a girl with the old sports model its like a 91 or somethin, real fast for a cav. The other is a newer convertible, also nice, lots of money in it).
Mine however has just been stereo worked, no real go. Im about to sell and get somethin new. Anyway, Ummmm...i had a link to some older cavvy options....
www.cavalierperformance.com is where i go.
I found this one too but i havent had time to check it out:
club.jbody.org
Hope these helped
