They're listing the standard 54606 arms on the spec sheet. Seems they're still blowing their horns about them being vastly superior to the old 2 piece versions. They're supplying stainless pins and low friction step screws. Those might help.

What I'm actually more impressed by is that RC Mart still has complete M03 kits for sale for $85. That is awesome. The black bling on the new car is nice too, I suppose.
