Awesome; hadn't thought of adjusting the diff position for the taller tires; will try that as well. I like the TE37 wheel in white, so I'll order that up in 0 offset. Which foams are you using? I'm looking at the HPI pro-molded green. Since I've only run one place, I'm not sure how to classify it. Although it's carpet, it's not a virgin rug so to speak, and is often a bit dirty.
Now just waiting on some parts ... ordered new new spool outputs, ball bearings all around and new titanium hinge pins. A new front belt is going on, back one looked fine. One of the front arms had a hairline crack ... nothing that would affect handling though. I think the real issue might have been a bit of binding. Will make sure there is free movement everywhere (and also check out that front belt on reassembly!)
