Bottoming out in the rear?
 

I have a 95 GT convertible, and with someone in the back seat, the rear bottoms out over bumps. Is this caused by coil springs worn out, or shock absorbers? coil isolators? any ideas? oh yeah, 95K miles.

If you have the original tires and rims it's most likely worn shocks.

yep, original 17" wheels/tires...and relatively new shocks, but settled for road handlers - and I swear from day 1 they didnt seem right. do the coils wear out?

Sorry man but those are junk shocks. The coils do wear a bit, but the SN95s have so much coil that it shouldnt matter too much. With the extra weight you are hitting the pinion snubber mounted above your differential. Try to find some good shocks for the rear, and you wont have a problem.
