You have any tire and spacer recommendations based on the above setup?

305 is a very large tire, I doubt any spacer will be needed in the rear. Front can probably use a 10mm, measure beforehand to be absolutely sure.

Aim for a tire with a rounded sidewall (ie: Toyo) or you may need to dial in some camber in order to prevent rubbing under load.
