No, that's not true - at least for me. What I'm saying is that, in the real world, the difference is not significant. It was very significant back in the 1980s, less so in the 1990s, and pretty much nil right now. The engineers and racers have learned what works with the FWD chassis and driveline orientation is not significant on the racetrack for an unlimited build or a build to a ruleset.
I'm also arguing against the "all things being equal" strawman, which again has nothing to do with the real world and is only used as engineering masturbation on Internet message boards.
