Pro Street vs Pro Touring.

[Cojohnso1]

So what I can gather. The primary difference between Pro Street and Pro Touring? Is chassis. Pro Touring maintains a more stock configuration. Mostly rear-end setup. Where Pro Street takes more advantage of shortened rear ends to tubbed wheel wells that better support adjustable racing applications. Like 4-links and ladder bar setups. This would enable Pro Street setups to accommodate higher HP engine and transmission builds?

I hear these "Pro" terms thrown around. And not sure if there is a more definitive description? And of course. What makes them "Pro" anything?

Pro Touring is more modern suspensions, bigger wheels, brakes, modern drivelines etc.
Prostreet is geared more to street legal drag cars

But if you dont drive it professionally, what makes it "pro"?

Pro Street was a moniker given to cars ( steel bodied, wheel tubs, usually cages etc) that had a resemblance of a Pro-stocker and were "street leagal", but it is an actual drag racing class of cars with rules/specs.
Pro -touring is more of a genre/style; same as a resto-mod I think that lends itself to autocross with a dash of drag in it.
In general I dont think the prefix of "Pro" applies to most that are called that.
