If you want a cross between prostreet and protouring I offer the M/T SR radial tire that offers the width of the old prostreet tires but now have a radial construction and wheel diameters of 18 and 20 and a speed rating H with DOT approval.

That's a smart man. Spend some time looking at pix of his car, TwinSting. In my opinion, it defines a modern pro street car. The biggest problem with traditional pro street cars are the goofy old school wheels & tires. Those big rear tires bounce the car around. (Ever seen a farm tractor drive on pavement? Same thing) The front wheels and tires are only good for going straight. And the traditional 15" wheel diameters do not allow for fitment of big brakes..

So....
-Let TwinSting advise modern wheels and tires.
-Add real brakes.
-Add modern front suspension from DSE, ATS, etc. (a-arms, spindles, springs, stocks, etc)
-And dial in your rear suspension settings for the street.

Will it handle as well as a true pro-touring car? No. But you will have a Modern Pro Street car that handles, stops, rides and steers better than any traditional pro streeter--all for minimal additional investment.

The rest is open to your interpretation: Fuel injection, seats, modified (smaller) tubs, etc. I'd love to follow along if you go the modern pro street route. If you choose a full pro-touring conversion, just follow Steve Rupp's lead.

Edit: Here's another good example of a modern pro street car.

I agree with Steve, I think TwinSting is a excellent example or ProStreetTour. One of out next in house projects will be ProStreetTour. Basically a Pro tour car with obscenely big rear tires. Without telling what it is, I think Steve will really like it.

I agree it would be a fairly easy conversion with the new tires that are available.

I am currently building a tt sonoma gt and the tire that i choose to run is 30.5 tall & 11.6 wide. I needed a tire that would fill the wheel well and not look kiddy sized.

In the end to get the correct stance took a complete re-do of the chassis. But the good news is the car your looking at already has had everything done to it. So in my book if the price is right - go for it.

The same way I feel about someone who donates a kidney to a dying kid or the people who are fighting to save the Rain Forest's in South America. I think you're a great man and should be commended for this extraordinary act of humanity. :D
