Yes for the Dirt Box portals there will be two options 13% and 8%. Those correspond perfectly with 37" and 35" tires respectively. But DaneJa is considering a setup from Curry and 74Weld that is 22% reduction which would allow for even bigger tires if wanted.He did mention that even though he was discussing the 4.7 inch option that had the 13% reduction....but there was a smaller portal of 3.5 inch with 8% reduction he would also have available in couple months....and if heard him correctly the 8% would match up perfect with 35" wheels.
