Like driving on ICE
Hey guys,
I have a problem with my '02 Coupe. It's just about perfect (28,000 miles), but it is evil handling going down the road in a straight line. It's like the rear end is loose and I need to correct constantly. My tires are brand new run flats at 28 PSI. The alignment is great according to Corvette Center in Newington. The shocks are stock but are quite stiff and seem to be OK.
The car is fine cornering when the suspension is loaded.
Going down the highway it's like I'm on ICE.
Any good diagnosticians out there that could point me in a direction to look at?
Thanks for any help.

Is it isolated at the rear or does the front contribute as well?
Correct to check bushings and links etc.
Plus, you might up your tire pressure. Mine wanders less with 30+ psi.
Let us know what you find.

+1. If the tie rods have any play at all the rear feels very scary. It's not easy to detect the play, it requires some muscle to pull the wheel in the front and push in the back to get the inner joint play show up.
I made a special tool out of a B-body steering centerlink so I could feel the suspension play with wheel off. It bolts in the hub and gives good leverage.
Yeah and 28psi is not enough, Goodyears will tramline with anything under 30psi.

I'd check the alignment. Could be off or the suspension could have some faulty parts.

WHICH run-flats? I have the Michelins, and they corrected all of the tram-lining of the OEMS.

I have the Bridgestone Potenzas. The Goodyear's were already replaced when I bought the car so I don't have any experience with those. I was a little fast to the keyboard

Loose Handling...
My 01 is doing the same thing. I'm going to get her up on stands this weekend and check it out and I'll let you know what I find.
There was a couple times when I had a problem getting the car (automatic) to go into reverse--as if the linkage wasn't attached; so I'm wondering if the two are related.
