Supastox - Racing mods

[whittaker52]

Hi All, sorry if this has been covered before, I had a scan through, but couldn't find anything.

I'm planning on building a Supastox over the winter, and i'm just looking at getting all the parts together that will get me started (indoor circuit) racing. Initially i'm planning on setting the car up as a 21.5 2S blinky race car - purely out of convenience with parts I already have - speed passion stock esc etc. Motor-wise, i'm kinda limited as there don't seem to be many stock 21.5t motors out there, but so far, the lead contender is the hobbywing xerun quicrun 21.5t 3650 stock motor. I had been looking at the speed passion V3 21.5t motor, but with adjustable timing, and no real way to lock at zero timing, it seems to be out?

I've read the guide that's on the GT12 facebook groups and that's clarified a few points, but I wasn't sure about a few things.

I'm planning on going for bearings all round - are there any major benefits over using ceramic bearings over just not metal shielded bearings, other than long-term wear? The bearing kit is about 3 times the cost for ceramics, but if it'll lead to better running, then I'd say it's worth it.

Ball diff seems to be a must as well, so that's certainly on my shopping list, as is the wishbone socket ball upgrade, but what about the wishbone upgrade that's available? is that worth building in too?

Are there any other things I should consider doing too?

Thanks in advance for any advice.
Best Regards,
Oliver
