Hi everyoneSo the latest with the car is changed from 19" to 18" alloys, now running 18" x 8J with 225/40/18 tyres on Eibach sportline springs which hopefully soon I'll change for Eibach pro-kit (it rubs ever so slightly at the moment sometimes). Anyway the problem I'm having is at high speeds even though I'm holding the steering tight and in one position, the car feels like the wheels/tyres themselves are moving. The best way I can describe this it's as though they are wriggling around a little or creeping. Another symptom is that although it isn't windy at all when I go round a bend on the motorway the car suddenly moves one way or the other exactly the same as it feels when you get hit with a side wind on the motorway all of a sudden.I've had a good google around and searched the forum. To eliminate the common causes the wheels have had their balancing checked and I've taken off the part-worn winter tyres that were on the front and replaced them with quality brand new tyres. The wheels aren't buckled as they are brand new.I guess the only other thing I could try is a full suspension setup but it only makes sense to do this once I've had the springs changed as this will throw the geometry out again and I'll have just wasted my £££.Any ideas?
