Anyone on coils without fender mods fit a 20x10.5 in front and 20x11 in the rear? If so what offsets would you recommend? Bout to build another set of wheels and trying to get as much concavity as possible without any fender mods

 

There is a great calculator and visual aid here: https://www.willtheyfit.com/

Plug in a few different offsets to get as flush as you want.

For example, for your rear, a 20x11 with a +35 offset gives you 18.7mm more "poke" towards the fender, which is about the perfect middle ground between a 15 and 20mm spacer that seems to be commonly used on the stock wheels in order to make them sit flush with the fender!

In this size, your 11in wide rim would also be 6.7mm closer to the suspension as well, so you'll want to verify if you have enough room.
