wheel fitment issue

Unfortunately, wheel offset and brake clearance are 2 different measurements. The design of the spoke face plays a role as well. Have you tried a spacer?

Started my big brake upgrade today. I knew I was in for trouble but I like challenges. So I have the stock 17" Z71 rims.

In order to get the calipers to fit I had to grind down the ridge on the top of the calipers, as some others have done, and I needed a 1/4" wheel spacer.

I don't care for wheel spacers but 1/4" is minimal so I felt OK with that. I used a single 2mm stainless washer to space the caliper. The caliper is not centered on the rotors, it is offset a little back, which allowed me to get away with using a single 1/4" wheel spacer.

My brain went a little crazy at first, but after some thought I do not think the caliper being slightly off-center matters. The pistons on the calipers will extends and contact the rotors, and the pressure on both sides should be equal.

I was worried about the wheel spacer, so I took some measurements with a digital caliper and I calculate that with a 1/4" wheel spacer I lost 15% of my thread engagement.

So I am running 85% of my threads on all 6 lugs. A little worrisome but not enough to deter me. Maybe I will get longer studs, but for now I am up and running.

Road test went great, brakes feel great. Next time I hitch up the boat I will see if it was all worth it.

tried using a 1/4" spacer which was not enough. 1/2" clears the caliper but I lose to much thread on the stud. The back wheels have no clearance issues just the front
