I have a RS4 3evo, and i know these are good basher cars, but i've also read that they can be made into decent racers. I'm curious as to what it would take to make this car perform as well as say, a NTC3 (basically, what it would take to make a evo competitive in a race). i've already got a few things down, like, adj. turnbuckles, tuned pipe, air filter, foam tires, and high-torque steering servo. how would the t-15 mill fare? or would it be wise to go with an o.s. in order to be competitive? do you think a radio upgrade is neccesary? i've had my eye on the spektrum 2ch radio just cuz i hear nothing but good about spektrum products. I'm not planning on going racing just yet, but as soon as i get the hang of tuning and can control my car well in parking lots, i'd like to try some racing just so i've got something to make it a little more exciting than just turning laps in a lot by myself.
