I extended the wheelbase with Unlimited Engineering Racer-X suspension arms. The tires work well and get decent grip everywhere! What I really enjoy about it is the extra ground clearance, this thing just floats over rough terrain and thick grass. The rims are Proline line desperadoes, half inch offset with 17mm hex
I did have to up the diff fluid to 100k or more. I think filled the rear diff with some 100k and put a little 150k in there too.
