Are you sure that the shock is not busted. I have seen a post on here somewhere about a person replacing their shocks and one of them was faulty, this make the rear corner of their car sit very low. If it's not that, I have absolutely no idea. Good Luck.

BlackZ,
What kind of times are you running in the 1/4 with that setup. My 84Z28 sits lower in the right rear also. Getting ready to get Eibach Pro-kit springs/Tokico gas shocks/strut kit from www.groupawheels.com
Later,
Craig

I have the same problem. I was thinking that the body has twisted from so much torque, or something. I'm hoping that if I install sfcs that would help. That is if I can get them on.

MY bird sits that same way, I have put new shocks on the back and swapped springs side to side , There is no difference, I even took the spare tire out, and there wasn't any change.

Black Z,
I plan on going to CGI motorsports next year for their one day track course for $150.00.
Send me an email at craigmaners@dotplanet.com since we are getting off topic. I would like to hear more of what you do.
Thanks,
Craig

maybe that is where the import demon sits. you know the one that keeps you from beating the imports...... sometimes. it could be me but I think they are partial to civics.

It could possibly be the rubber spring cushion on top of the rear springs, both of mine were worn out, and when I replaced them it raised my rear about an inch or so. That's the only possibility I can think of off the top of my head, and a simple fix.
