I Ben, Sorry back to cars, all the bushes, track rod ends, bottom ball joints and shocks have been replaced at the start of the year and set up correctly, as I have not had the car a long time tire pressures are what they say in the hand book for 205x55x16 tires 34psi all round, I do know my 1985 Ur quattro runs 2 psi less at the front because at the psi in the hand book the center of the tires is run out before the outer edges, but that takes a few year of ownership before you find that out, what psi do you run?

Heh, I was taking the p with the, "if it's an english success, then it's english. If it's a scottish/welsh/n irish success, then it's british thing". I am aware it happens, London takes the credit for Manchester stuff all the time.
You say setup correctly? by whom, and by what amount?. Oversteer could be toe out on the rear, and toe in on the front. As the weight shifts onto the front outside wheel in mid corner, it steers more, turning you into oversteer. Swap that to toe out on the front, and it steers you out of the oversteer. You can check the tracking using a length of string: https://www.youtube.com/watch?v=wjZUu_d08t8 If you stiffen the rear arb, you will get oversteer. But you don't know if it's the arb, or tyres at fault. Maybe swap the tyres around, fronts to rear, etc, and see how it handles then. But you really need four matching tyres, so the conditions affect all the tyres the same. I run 36psi too, in my 80 and 90.

Agree with Ben get 4 new tyres, preferably some Assymetric 2's
you know your car deserves it.Does an S2 deserve less? Of course not. Only then can you compare before and afters. |

I run 36psi too on the quattros'. I have whiteline ARB to fit to my CQ and looking forward to the bias to oversteer, it's definitely my favourite way to slip! |

Hi Ben, We better say away from the Scottish, English, British thing because we could be going at it for days, I took the car into a place in Bathgate that did 4 wheel alignment and they set it up to the setting they in there system for a 1991 S2, don't get me wrong the car drives and handles well, If can go back to the original quattro when it first came out it had a rear anti roll bar but it was removed in later models due to the rear end of the car snapping away mid corner, I think I need to take your advice and fit all the same tires to all 4 corners, this seams the only way forward to eliminate is it tires or set up.

Tires now on order £187, will be delivered on Wednesday, now down to the garage to find a boost leak that has developed today, watch the 3D printing post I have going just now because I am printing the bungs just now to test for boost leaks.

Just a heads up with regards the "paint" on the Whiteline. I've had one fitted on the rear of my 90 for a few years. The paint isn't that great for good old British weather. Within no time at all is was looking pretty sad for itself.

New Avon tires fitted to wheels and now on car, out for a spin last night in the dry, at normal road speeds the front end is turning in quicker, wet weather to day but to much work to do, may go out latter. manufacture dates on the old tires removed from the car "4409" 44th week of 2009 on rear and "2508" 25th week of 2008 on the front, old tires may have been the problem.
