I have a problem with the 951, the rear tires rub the fender. I have read the archives and most of the problems seem to be based on lateral loading, my rubbing occurs in the vertical axis, mostly during acceleration and when people are riding in back seat.

My question is could the torsion bars in the rear wear out allowing the body to rub against the tires under acceleration? I have Koni yellows on the rear, they seem fine when I do the bounce test for the rear. Also from the previous owners receipts, they were installed only about 40k miles ago, shouldn't they last a bit longer? Do I need new shocks, or can I just take out the konis and adjust them and reinstall?

I also have a weird steering problem, where it seems to get harder to turn the wheel after the wheel is turned a little past dead center. Also turning left is easier than turning right???

Anyways thanks for any help in advance.

What size wheels and tires are you running? And what kind of wheels?

either get lower profile tyres, raise the rear ride height, or roll up the drivers side fender, as I have done. The 86 and 87 951s have a square lip in the fender, whereas the 88 and later cars the fenders where pre-curled at the factory.

Apparently this only happens on the rear driver's side, because all porsches of that vintage have thier rear driver's side wheel stick out a bit further than the pax side rear wheel. (This is what have been told by a body shop guy that has put a lot of porsche's on the body jig to line em up, and measured them..)

Also check your alignment... adding a bit negative camber to the rubbing wheel might cure it. The fronts are definately out of alignment if the steering doesn't feel right.
