Is It Possible?........

I think the original definition of “pro-touring” was something that had a modern feel and amenities. It has since evolved into the thinly veiled race car that can be street drive, much like most styles do. But like Darter6’s cars there is a broad range and I don’t think ultra low profile tires and full aftermarket frames are required to be considered pro-touring.

Use the same formula for the suspension and put the wheels and tires on it that you like. If you’re not chasing the last 10ths of handling, accept what you get and enjoy it. It will probably be all you need and more than you expect.
