Sounds like we have a similar electronics set up

I need to get track tires though. I bought Proline switch 2.2 tires and T4 rims for my 10T, for an all terrain type fun tire, and I thought about getting them for the track also, thought I am not sure they would do that well though.

Ususlly track conditions are un preped, clay with a light to medium dust, with the exception of race days.

So far on my other R/C's what I have been most happy with is Hole shots, though I havent found them for the sc10 yet.

I know that rear rims from the J82 / T4 conversion work in the rear, as they are off set enought to still fit under the body.

Do you know if there are any other standard 2.2 wheels that will fit properly under the body, that can use a standard 2.2 truck tire, rather than the sc style rims that come with the truck.
