I really hate to spend ANOTHER $60 on just this part, but if I don't have a choice, oh well

you need tamiya wheels with this diff set.they are different.
and also aluminium knukles for front.

I never bend the hubs. but I was bend an optional aluminium rear axle =)

I would just replace your bent part for now.

Has anyone figured out a good thrust system for the foam axle diff? When I tighten mine down the diff action starts to bind up unlike the regular rubber tire diff... I've tried using the option Tamiya F103 thrust bearing and it still is bound up.

Well I got the new diff in and got it all installed when I realized what you were saying about the different wheels needed. I knew that different wheels would be needed, but I just assumed this was in reference to the diameter of the inside of the wheels not being enough. So can someone post the exact part number for the wheels needed? Thanks

yeah, most companies include a 90mm wire, which is only good in TC's. Pan cars need a much longer sensor cable

Dynamite made one that is 2200 that I'm trying out. A few mm wider so you have to lengthen the bolt down holes a little on the mini battery mount. Battery is not as punchy but it gives you a bit more run time.

Get the 150mm TQ racing wires. The best for pan cars.

I ordered a 120mm one from hobbywing. Through some research its the same as the LRP sensored cable, just rebadged. and it is $2 (plus $3 shipping) instead of $10 plus the $3 shipping.
i may order that cable just to be on the safe side
