Looking for anyone who has experienced the same issue -
R53 manual with Quaife diff fitted. 16 inch wheels and 205/50/16 tires.
When letting off the throttle it pulls sharply to the left, and applying a good amount of throttle it pulls sharply to the right!. if your following, the car, you can see it move about the lane.
I have had alignment checked twice, all is good, can't see anything loose or feel loose, pretty much poly bushed all round.
Would a cheap brand of tire be able to cause this? Recently bought a 2nd set of genuine wheels with nankangs on them as road wheels.

Thanks All
