You can just rotate the motor away from the waterfall

Can't you just index the front piece on them? To get the tabs towards the rear?
Just an idea.

Can some of you please share how you are running the front end of the buggy in terms of Axle spacers and overall front end width? How many spacers between your axles and bearings if any? I've noticed that my JC Inverse wheels will bind if you are running the narrowest setting. I think I could run them with .5mm shims on the outside between the axle and the bearing and with the Kyosho stock wheels I can run them all the way flush.

Follow up question, are there other aftermarket wheels that can run in the narrow setting? AKA or JC Mono perhaps? Thanks in Advance!
