Years ago, when I put drop spindles on my Expedition, I had to run 18" wheels to clear them. This was fine, as I'd bought a set of Lightning wheels for it. I ran into the same issue with the spare, as we're discussing here. After much looking I couldn't find any solution for an 18" spare with that bolt pattern, other than a custom steel wheel for $$$. So I bought another used Lightning wheel that was badly curbed and spray-painted black to use as a spare. It was $30 if I recall.

So I'm thinking you could just buy a used OEM wheel that clears. There are plenty of OEM 20" wheels out there with peeling chrome, or curb rash, that are almost worthless except as a spare. With the OEM tire diameter, it should fit in the spare well. Or am I missing something?

Anyone out there do this swap so far? I purchased the callipers, assembling the rest of the items now. Posted in another Post, but will ask the same here. Anyone out there able to provide the dimensional information for the PPV rotors on the '21's? There are (2) part #'s listed and one is about $200 more than the other. I know they are '16 in.' but need to know all dimensions to try and find alternatives and confirm they will fit on the '15 to '20 hubs/caliper to bracket layout/etc. Any help is appreciated!

I'd love to piece this together as well. Any rotor p/n's yet?

I see post 6 but its the GM aftermarket system. I would think individual pieces parts would be cheaper but maybe not.

20 inch won't fit in the 18in slot I tried

The overall diameter of the spare wheel and tire should be the same as the rest of your alloy wheels and tire combos. With that I'm confused why a larger wheel will not fit in the spare spot. You have to use a thinner tire with a larger wheel to achieve the same overall diameter.

This is the part that concerns me the most. Does the spare tire area not accommodate a tire/wheel assembly that is wider (regular size tire) than the original spare? I would think the diameter of the spare and regular wheel/tire is the same.

I'm not sure that thread/post is correct.

Isn't the PPV brake kit a 6 piston front?

It seems like some websites list out the parts for the PPV package:

Looks like an alternate to the Brembo rotors.
So theses brakes are plain versions of the Brembo kit to my knowledge and the thought is these rotors would work as well? Have a ‘17 Sierra and weighing brake options in a couple thousand miles.

Description says they work with Brembo calipers. Probably best to ask the vendor.

Here is the VIN verified part number for the rotors.

84865905​


I say VIN verified because my awesome GMC House Parts guy looked up the vins on a few 2021s that they had done the tinting on.

Now can someone find non GM brake pads that aren't as much as a caliper?

Oh and sorry to bump an old thread

I had found the part number on there but went to my dealer to verify.

The pads and calipers are expensive. Each caliper was over $500.

I guess compared to Wilwood or Brembo calipers they might not be that expensive.

I did find some Dynamic Friction branded pads that were reasonably priced. I will not be home for a week and a half to verify if they fit the calipers I ordered from RockAuto.

Any of you players try to fit some of these brakes on an NBS truck yet? Is there a thread for that?
Several guys on the NBS section have done the swap,
Ask on that section and they can give you more details on the swap

I am working on it. I have all the pieces I hope. Unfortunately it will be a week to a week and a half before I can play with them.
