I run the factory 11" ET62 rear rims with a 35mm spacer up front and it works fine for me, and it would also work fine with ET60's. The important question is "will the rear rims clear the front brakes with that spacer in place?" They should, but it's best to test-fit first.Considering a 2016 GT350 Track Pack that has the LMR GT350R replica wheels on it. They are +60 offset according to LMR https://lmr.com/item/SVE-177912H/sve-r350-wheel-black-19x11-15-18 . The car currently has them staggered but I thought I would buy two more 19x11's to run a square setup if the deal works out. What spacer would I need upfront for a +60 wheel or will it even work at all?
