Well, welcome to racing my friend!... To me, on-road is about the track... even if you are making your own in a parking lot. I would recommend a brushless setup for sure, but just remember throttle control. I am currently running a 3300kv & I never get more than 1/2 throttle on my straight away. Plenty of speed.
Most importantly, Enjoy it ... let me know if there is anything I can do to help. Have fun & welcome.
