Rear-end vibration at 90 mph

I was driving on an interstate (traction control OFF) at 70 mph in 6th gear. To pass, I downshifted to 5th and accelerated to 100 mph. When I eased off the gas, the rear end started to shake and vibrate as if I had 2 flat tires. I slowed down and pulled off the road to look at the rear tires. I turned off the engine and examined the rear end. The tires were OK. I found NO problem. I restarted the car and drove another hour under similar conditions without a recurrence of the problem. It seems to me the problem (ABS? Traction control?) was under computer control and when I restarted the engine, the computer was rebooted.

Has anybody out there experienced similar problems with the Z06?

Smokewagon,

First thing I'd suspect is a concrete section of road with drainage grooving; that surface will create vibration and control issues induced by rapidly changing directionality impulses. I got a lot of that on I-80 in IL and OH during my post-delivery treck home to MD.

Catches ya by surprise. Feels like one or more flat tires. Doubt it's mechanical.

c4c5Specialsit, You're the man.

But the symptoms smokewagon described are provoked whenever a C5 is driven over a concrete road section with serious drainage grooves. The grooves seem to give the meaty C5 or Z06 tires conflicting directionality input that feels like severe vibration accompanied by a sense that a tire has gone flat.

This has happened to me a dozen or more times with the Z06. In each case the symptoms disappeared once blacktop returns.

Just more input.

Smokewagon,

Your additional facts eliminate my theory from further consideration. Back over to c4c5Specialist. I'll be following the thead. Good luck.
