I am looking at getting racer tires, but I'm not sure how hair-brained my idea might be. I have a set of C6Z replicas, but the rears are only 9.5" wide. Would this work or would I have to have too much spacer on the studs for this to be safe for auto-x? Granted this is all based on me making sure the bolt pattern is right, but everything I have researched says it should fit. I will be test fitting this weekend.
