You should have a few of the San Diego guys, especially anybody that races, drive it and have them tell you what they think.

Find a shop with a shock absorber tester.
The type where you put the car with both F/R wheels - or maybe just one wheel - on a machine that gives the wheel a push.
The graph will show the dampening = shock condition.
Worth a try.

IMO starchland has a point with the diff action / caliper sticking comments.
How long ago was the diff oil changed?
If you don't know you might as well get some fresh oil in there.
(now... we could fill another 50-100 pages on WHAT to use - and "we" actually have on this board so if you search for it you will find it)
Personally I would put a 75W-110 (if you can find it) or a 75W-140 in there.
1 quart will do, you actually need 0.8 quart or so.

Also worth a try.

Do any of the rotors get hotter than the others?

Bumping this old thread because I'm experiencing a similar issue. I noticed it after getting the car back from the shop after a small car accident. Lower control arm on the driver side front was replaced since it was slightly bent in the accident, but everything else was fine and the car was summarily re-aligned and everything checked out. I did however notice that one of my front tires has some pretty serious inner camber wear. I drove it on a stock wheel with a healthy tire, and the issue disappeared.

So with said, would inner camber wear on one of the front tires cause the car to tramline? just paranoid after the accident that something else might be off.

of course. when you hit a crown in the road did you notice it get worse? extreme rear toe will cause twitchyness as well from my experience.

From my experience, tire design and road conditions can cause tramlining. My Michelin SS's tramline in the rear on a section of concrete freeway that had rain grooves troweled into the wet concrete. They do not tramline on un grooved surfaces. My previous tires did not tramline on this section of road. I have the UK alignment on an AP2.

Yeah, I did. I figured it would be the tire. Thanks!
