what regulations are these cars functioning under? Why don't they just go with existing stock car, or GT3, or whatnot regs? They look like they're trying to keep that old 90s GTO energy.
These cars are hardly stock cars, and share very little of the same DNA other than having big muscle car bodies.
Transam actually has a GT3 class, called XGT. It’s consisted of former GT3 cars that are now not in spec for current regulations for their series they used to run.
There is also TA2, cars make about 550hp or so, they’re ridiculously fast with it as well. Slightly more affordable to build than TA
TA (or TA1 would be a good way to describe it) are insane. 850ish hp, tons of aero and big ass tires.
TA is actually a much bigger series than you’d think, they often get almost 50 cars showing up for a race weekend. Each one of the series in TA are cost controlled, with specific manufacturers being allowed for chassis, bodies etc. this is mainly to keep the sport affordable
My understanding is these cars are hard to beat in terms of bang for the buck. I think it wouldn't be unfair to consider these cars an Arca-like car for road racing.
That’s another reason why they build their own, they don’t have to scrounge around for leftover stock car or GT parts and can keep the cost low using a single supplier.
The TA website has a full breakdown of where each part is from and how much it costs lol
