I did get a reply from Sean at Lucky8 regarding the OEM steels and the rear caliper swap.

Here is the information they provided.

It seems they are not able to answer my question.

Thanks @GavinC for the contribution to the community!! That is GREAT news to hear. I'm now motivated to swap mine. I'll spare everyone the old, balding, fat guy - so I won't model my conversion when it happens...

 

Those tires look great on the steelies, any details on them?

 

They are 35" tires in this picture.

Other work was needed to fit those bad boys but I did clarify with Sean that if keeping 32" tires, only the caliper swap was needed. Just like with the Tuffants.

 

Oh duh no wonder they look so burly lol

 

No worries Grouse. Happy to add something small to this great trove of info. It's Sean at Lucky8 who deserves all the credit. He was gracious enough to reply to my questions. Really top notch stuff from him and the Lucky8 team.

I've not even got my Defender yet (October 2021 is the eta) but have been geeking out tremendously on this forum and elsewhere. Learning a lot from y'all.

Plan is to get the steelies, calipers, fit some 255/70/R18 KO2s and hit some local trails in the fall.

If the KO2's behave well on snow, I plan on selling the OEM 20" alloys with the factory Adventure tires to recoup some of the costs.

@GrouseK9 If you do the swap, let us know how it goes. Any tips or pointers would be most welcome.
