had the same problem, car was all over the road giving no confidence and braking was quite scary. was one of the steering rack bushes i think its called. poly´d it and was fine

later had a new set of toyo t1-r fitted on the back and i was back again, no responce from the rear making highspeed lane shifting very unstable. have always used the toyo´s but something must av been wrong with this set, went back to originals and traction was fine again.
