Try Horizon Hobby first. They're the distributor for Sportwerks. They pretty much have all that you'll need to get it going. And as a side note, let me know how you make out. I have a Mayhem RTR on the way and I hope that HH gives good service. I haven't found any other site that has as big a lineup of parts and upgrades yet.
I was at the local track yesterday and there were already a couple RTR Mayhems out there..The first upgrade I would suggest would be the shock towers that come off of the Non-RTR version. There was a guy there showing me the difference between the two and how flimsy the RTR towers were..
i have been lookin all over to stock up on parts as well..i have the "pro" version...
i am having problems getting my ofna hyper 8-port installed...motor mounts seem to be too "short" if that makes sense...and the slots allow for lateral movement to set the mesh, but no way to back them off any...
some spare parts are out of stock right now till april
front arms , shock collars, pro rear tower...
I have a fear amount of spares already:
1 complete diff with plastic shells and bearings, complete all screw set, 2 sets front and central drives ti.nitrit, 13T clutch bell ti.nitr., complete front suspension (not arms), extra roll barr sets fr/rr, 1 rear suspension arms set, diff gaskets set, 3x16 mm screws+ locknuts blue, 1 rodbagset, 1 complete plastic parts set (16 items), red option mediumsoft shockspring set + blue mugen soft springs, kyosho kanai blue metal cluchshoes, 8 mugen shock dustboots, 1 blank mayhem body
even my lsd is ordering the items I want to be send
you have the body surely in stock at horizon
