What I mean is, has anyone out there raced against themselves
where they bought a new car, set it up, and timed their runs on a track. And then do the same exact thing using their old car? And then keep refining each car to make it continuously beat the other? Any heartbreaks from realizing that you were faster in your older car?
Seems to me like it would be a nice thing to test out. Especially, say, when you go from a TC4 to TC5. Or an HPI Pro4 to a Hot Bodies TC? I.e. - going from shaft to belt?
Anyone out there had enough time on their hands to actually do this?
