car won't go straight
I have a 2008 right hand drive M3 imported from UK. I put new RE11 tires on it with fresh wheel alignment. The alignment reading was normal but the car has a tendency to pulls left. If I let go my hand going at 100kph, it will take 5 second for the whole car to drift one lane. I brought back to the mechanic, they have measured the wheel base, disassembled the brakes, swap the springs, new bearings, new alignment... There is no improvement. Any suggestion?
