Hi Road
The guy you see sat in the car is my brother who owns a tyre/exhause garage here in the UK hence tyres at cost. He re ballance and then balanced again.... same terrible vibration..... I think it has to have something to do with the weight of the 18's and the whole car is set up for puny 16's and effeciency.
Maybe there is somthing in the ECU stoppoing us changing these wheels sucessfully...
