I contacted my local ProComp dealer interested in buying these wheels
He called me back with the price of $80/wheel (great discount through a friend) but said he had some bad news. He said that the 2011 Titan Pro4-X has calipers on the rear wheels that are different sizes. Specifically, the left rear caliper is larger than the right rear caliper and, therefore, the wheels wouldn't fit on my truck.
Can anyone verify this? Anyone ever heard of this before? Any ideas around this?
Thanks for your help!
