I can't speak to the sealed gear diffs listed, but I have used the ta03 ball diff. When we ran silver can motors, it was the setup to run, but I tore through it in no time with brushless. Had better luck with the stock gear diff and extra side shims on the spiders to tighten it. Lasts and stayed more consistent.

I will be acquiring a M05 in a few days.......For those who have tried a Yeah Racing 38t sealed gear diff, is there any problems using this with stock gears? The stock open diff is 39t, so why is the YR diff one tooth short? In my mind this would be loose, not mesh well, but I don't know. I see they did make a separate 39t gear for this diff sold separately, but seems this has been discontinued. Also the SpecR, and 3 racings diffs seems to be 39t, but those are hard to source now too. Maybe just going with a TA03 ball diff is the way to go...

M chassis gears are kind of loose at the best of times. Dropping a tooth on the diff doesn’t make much of a difference.

Fun run with M03 today; this car was built for TCS back in 2005 but I fitted a 17T with Novak Cyclone TC this afternoon after my Novak 610HRV burned itself out this morning. Note the inside rear wheel on cornering. The S-Grip tires from 2005 still work fine.




Where to get a body that fits an M-03M these days? Do some of the latest M-chassis bodies not fit, like the Mazdas etc?

I think the Mazda Demio is a long wheelbase. Do you need to stick to Tamiya bodies? The Protoform Europa M, Bittydesign HC-M are decent options for mid.

Oh yeah, switching to long wheelbase is not a big deal, but just want to make sure those bodies fit an M-03. The Protoform and Bittydesign fit?

They fit my M05 mid with plenty of clearance, they should fit an M03 too. The Protoform is a bit wider than normal though, so unless you use offset rims it might look a bit odd. It was designed around the Ride 3mm offset rims.

Trying to gear up for some summer parking lot racing (hopefully). Looking to get some SWEEP tires. Any recommendations on the SWEEP compounds and inserts for concrete / asphalt?

36 EXP front, something soft on the rear. I'm not happy with the Sweep options for the rear, lately I've been running Team Powers 28 rear with the Sweep fronts.

Guys,
I've left the TC scene for quite some times now and would like to get 05 kits for my kids. Is 07 any better? Also, can anyone point to a well-stocked online seller. We've don't have access to local tamiya store anymore. Thanks.
