I did the MRR 755 on the stock tires. I Sam going to use the Black Tridents with winter tires. I have the z51 with the front lift and dropped the front and rear 1 inch. the dealer did the work for me since it was in there for a leak in the transfer case. They lowered it, put on the new wheels and aligned to factory setting (not track). No rubbing and it sits right... the combination of lowering it and the MRR wheels changes the stance for the better. There is no rubbing at all. It is the way it should come from the factory. If you dont have the front lift and the Z51 package it is very easy to lower the car. If you did do the front lift look at Cicio Performance, they make the parts for the front drop. Total charge for lowering it, installing new wheels and alignment was $472
