u/Formal-Standard-6883

Hey all, I currently have the R5 with the standard wheel it came with. Ive recently purchased the clutch, shifter and hand brake. Im absolutely loving this setup more than I thought possible. I already want to upgrade the wheel, unsure which one, but I know id like a 13 inch wheel. Is my R5 wheel base sufficient for a bigger/heavier wheel? Or should I kick it up to the R9 or R12?
