Have you rechecked your air pressure in your tires? As everyone said check alignment as well but if its just slight issue of going to the right it could be just from the way the road is. I also know when i had my stock tires and wheels my car would pull somewhat but with my different wheels and tires it doesnt do it so much anymore.

 

machiii in sf will send you to faxon garage. they do good work.

 

Ya I run 35F/33..Im gonna try and up it to 36f/34 and see where it takes me...wheels dont shake so its not balancing..
