Jim, it's adjustable everything apart from top mounts! TCA's are rose jointed and the only bushes it has got are polyurethane. It has got a Quaife ATB diff and to be fair, this issue has only started since I had it apart for the engine so I think it just needs a geometry check. I've been around the suspension at the front and nothing has any play in it.
I got Danny at Adrenaline to set it up years ago and it was a hell of a lot better. Pulled straight under hard acceleration. before then it was an absolute pig. Now it drives straight but pulls like a bitch under hard acceleration. I think the diff is being unsettles slightly too. I had to fight it up the strip at Pod last week end but it still pulled straighter up there than it does on the road. If it's raining it's totally impossible to keep it straight. I'm talking 3rd and 4th gear too!
