I know it is Friday the 13th but I did it anyway. I just installed my new Blizzak's mounted on 15" Borbet Type E wheels. I used the bolts that came with the package from the Tire Rack. I though everything went great but when I started the car it would NOT MOVE!! It was just like it was bolted to the floor. I swapped the new bolts for the factory 5 spoke bolts and now the car runs great. I will contact the Tire Rack and get new shorter bolts with the conical shaped seating are for the Borbet Type E's but my question is DID I DAMAGE MY A4?? I did not move the car at all I only hope when the bolt bottomed out it didn't bend anything.<p>Any comments???<p>Roy M 2.8q Tip (With new shoes)
