Double check that alignment. I've had a shop give me toe out once.

First thing I would do is jack up all four and look for any play in suspension. The next step is differential. There is a good chance the rear differentials is locking up more than it should. If all checks out, last I'd do is alignment.

Alignment was done at Evasive with me sitting in the car, and literally watching the adjustments as they were being made.

I will, however, double check everything.

Look for damage/wear everywhere in the suspension, esp. bushings (note - FLCA bushings are hard to check when mounted). Diff mounts too. Then take to Darin and have him examine everything, incl. F&R subframes.

Eh, just drive it faster through the corners. The higher speed will create more rear downforce and fix your balance issue.

Seriously, check the rear toe links. I had my T1R BSK for around 10 track days and the rod ends had so much wear that the toe could slop back and forth about 1/4" each.

I'm thinking I have something bent.
They're all right handers.



Mike, does your car behave the same way in left and right handers or is one way worse than the other?

GL to both of you, hope you get it fixed quickly

It does the same both ways.

I stopped by Rising Star Motors after work today, and they did a quick check on the suspension components... and nothing is bent/snapped/loose. Bushings seemed okay. Ron did a quick test drive of my car and did notice that he could get the rear to come out rather easily (deserted parking lots are nice for some quick testing like this). I was actually hoping that something would be broken/snapped so that I could just replace it and be done with this. I was completely frustrated this entire weekend at CVR.

I'm going to try to set a late appointment at West End this week and get this sorted out; I'm supposed to be driving at WSIR this weekend, but I'm not going there with this super happy rear end.

Wow Mike that sucks! I hope you are able to get it figured out for WSIR this weekend...

blown shocks possibly? shock doesnt necessarily need to leak to be blown. So a visual inspection may not catch that.

If you push on the rear of the car does it feel smooth when you push it down or does it feel like you're breaking something loose before it starts to move?

The thing that sucks is you might not notice anything wrong because of the lack of load.


It really seems like it's a toe out issue in the rear though unless torsen diffs can do funky things.
