Well I had a RDX and I have a FT TC4. I have zero problems running the exact same laptimes. I will say each car drives a little differant on the track.
Ran my TC4 tonight and it started off not handling well but each heat the adjusmtents I makde each run dialed the car in. For me the car is very easy to adjust but not too many adjustments. Not saying the car is the best but it is as equal to any of the other high dollar cars I have ran and I have tired most of them. For me ease of getting parts and simple to work on.
