It's, me and I think you all know what I am going to say! YOKOMO MR4 TC SD (that is the shaft drive silver one in case you didn't know). Exellent build quality, very tunable with plenty of adjustments, pretty good price with lots of good stuff as standard equipment, and superb handling. To be fair, it is a little fragile if you whack things often, but that is the only sore point. Very fast car!
