Handling
I recently purchased a 2002 Coupe W/63K miles. I have noticed at highway speed a yawl - car wants to drift or grab the road (concrete) left and right. When de-accelerating car moves left and right. Is this worn tires, look about 1/2 tread left? The car was upgraded with brake calipers and I have noticed a spacer on the front hub, could this be a cause of the issue? Good Year R/F air pressure between 30 - 35 lbs. Not sure where to take car for inspection, Help Jacksonville, Fl.

Most cars with wide front tires will do this. The runflats, so I've heard, make it even worse.
My car, as well as my previous SS Camaro, would follow the grooves in the pavement too. The wheel ruts on some interstates are pretty bad and I have to really focus to not let my car veer into another lane.
Supposedly, the lower your tread, then the worse this becomes.

All of the above. Check to see if you have the stock tires. Spacers should be for different rims i would guess. A lot of stock corvettes wear the tires on the inside bad. I would have an alignment or have it checked and ask them to check the play in the steering too. Cheaper than replacing the tires. I have seen tires that look great on the outside edge and are worn out on the inside.
Tire pressure should be 30lbs Cold.

The side to side movement on road grooves is called tramlining. Like a previous poster stated most cars with wide front tires do this. The Run Flats do make it worse. I switched to non RF's and my car rarely does this any more.

I dumped the runcraps and no more tramlining. I bought the GY GSD3's.

No runflats on the Z06, but I still get tramlining on my Michelin PS2's. But, it's not bad, but it was better when they were new. I have 30,000 miles on mine, but still have at least 1/3 tread on the fronts (back were sequentially replaced for free due to punctures). I don't do many burnouts.

I experienced the same conditions with the car tramming as it would go down the road, with my OEM, 20,000 mile 8 year old G/Y RF tires. I replaced them with new Michelin Pilot Sport A/S ZPs (run flat) tires and have no such problem any more. The new Michelins cured the problem, 100%.

the car i bought was road raced and as a result the suspension was set up for the track...the former owner had a few degrees of negative camber set into the suspension..when the tires were a few pounds low on air (after it sat for 1 month and it was 10 degrees out) i took it for a ride...the car was all over the road... lesson check the alignment and air pressure..

I had a similar issue with my 2001 C5 when I first bought it. A friend told me that the OEM runflats were the problem. So at 29000 mi. I replaced them with Goodyear F1 GS-D3 tires and it was like I got a new car. The tires were definatly my problem and the new Goodyears completly changed the handling of my car for the better. It now handles and responds like a true sports car.

Im going to try coilovers
I have added larger tires and it will do this sometimes. I have been looking in to pfadt coilovers. i have heard they can eliminate some of what we are getting.
