I havn't posted before so I'd better introduce myself before I post a question.
I'm the proud (and rather paranoid) owner of a '94 Supra twin-turbo. I've had her since April last year and although I've had a few problems she's been utterly awesome.
.....apart from one aspect.....
THE HANDLING
Before my Supra I had an FTO which went round corners like it was on rails and felt good at all times. The same cannot be said of my Supra.
Ever since I got the Supra I've not liked the way it handled at all.
It feels like it follows every camber change in the road. Sometimes it's like it's trying to pull you into all sorts of places on the road. Under braking this seems to be rather worse. At high speed on a good road surface it feels fine. It's B roads where it feels just terrible. It's very difficult to drive quickly because you're always having to correct the steering.
I didn't set about trying to fix this straight away after I bought the car as I wanted to do some research into the problem and also fix a more fundamental problem in the one of my front wheels was warped and a rear flat-spotted. Now I have nice new wheels, running on 2 year old Eagle F1s.
Also, I've been told that Supra's are sensitive to being lowered and also to running larger than standard wheels. My suspension is about 1 3/4" lowered and I have 18" wheels. (Standard wheels are 17s) The only thing is that I know of dozens of other Supra owners who run the same setup of even lowered further or have larger wheels and none of them complain that their Supra is trying to kill them all the time. In fact most say the handling is awesome.
Now that I've sorted out my wheels I recently had a full suspension geometry setup done by a local motorsport garage to try and finally resolve my problems and they pretty much didn't change much apart from saying that I had 3 degrees of positive camber dialed in at the front. (Which apparently is bad) This they changed to be about 1 degree of negative and claimed this would radically change the handling for the better.
Now the turn-in is much better and once you've committed to a corner the handling is great. But the twitchiness and pulling with the camber is still there.
I'm reluctant to go back to the garage who did the suspension setup without more information and perhaps a suggestion as to how to fix the problem because I took the guy out in the car before he did the work and he couldn't see any problem with the handling. In fact he described it as "Supra-like".
What I'm seeking is to understand what is making my car handle in this nervous, twitchy and highly irritating manner.
Thanks in advance.
