I had my wheel changed to M Sport Wheel yesterday (done by my dealer). What happened to me was that I now have to hold the wheel a bit way to the left to have my car go straight.
Was it possible that they aligned it wrong? Would you be able to fit the steering wheel back if the line on the wheel and the line on the column were not aligned?
If that's not possible, maybe my car need wheel alignment. But if that could happen, I think I have to follow this guide to see for my eyes if the wheel was installed properly.
