hey that's actually nice that GMC dealer used actual Lexus parts! ya I agree they probably did get a nice wholesale discount being B2B.. it's crazy some of the discounts a business gets at the wholesale level!
Actually it's through the GMC dealer that I learned, caliper bolts is part of a Lexus brake job. I bought some for the next one, and they're a bit pricey. I really don't think they're torque to yield or anything. When I got the car I thought oh s*** did they use Centrics? Because they have the same cross hatching on the rotors. The Toyota part actually has a grayish hat, whereas the Centrics are black. Rotors are still on the car today, although the vanes are severely rusted
