My buddy has 4, 225-45-17 RE-11's which he is going to sell to me dirt cheap. They didnt fit well on his car. I am thinking of buying them as extra sets when my fronts wear out.

Will it unbalance or hurt performance if i run an re-11 front and starspec rear? I am at a pretty big stagger so I doubt ill notice. Even when its time to replace the rear i want to stick to the starspec because they do not make anything that wide Re-11. The 265 wide really helps keep traction with my supercharger so im not going any narrower on rear.

 

not at all. drive it carefully until you understand the limits and then have fun.

 

Those two tires are very similar in performance. I don't see any issues but I would say to find out where the limits are with the tires. You don't want to be suprised when you need the car to handle its best.
If I can help with the tires let me know.
