I'd also like to add, at the GORC a few weeks ago, my car was 100% USVTA legal (as it always has been). Darkside's was not (it was legal for that race's specific VTA rules). Some rules were relaxed for that race, and while I disagree with it, it is not my place to decide, and the only thing I can do is govern my own car.
Keep in mind, no amount of modifications, legal or otherwise, would have made my car competitive with Myron. The driver skill difference is just way too massive. The point is, if it works for a track or club, and gets people racing, that is what matters. If it works, then sharing it here might help other programs get started or do better, strict rules or otherwise.
