I'm not sure about the class rules but can you run the midwest rear in a class like that since it doesn't have the same mounting points on the rear as a stock torque arm? Or is he making them different now so you can mount a stock style arm on it?

You might want to clarify what True Street class you are referring to and the rules to it, and that will help with the responses. True Street is run with many different racing organizations.

Vehicles are required to make three full passes in order to be included in the final average ET tally. All vehicles must run three passes in the same order as the first pass, any attempt to gain additional cool down time between rounds will result in disqualification. The only possible exception to this rule is the use of a parachute, if required by vehicle speed. One crewmember can be placed in the staging lanes to aid in the re-packing of a parachute; however, chute must be re-packed in a manner so as not to be disruptive to competition rounds.

During, and in between, the back to back passes, no changes may be made to vehicle other than lowering air pressure in tires. Fresh nitrous bottles, fuel, and ice may not be installed/replenished. Vehicles with air-to-water intercoolers may not add ice to intercooler tank between back-to-back passes, even if intercooler tank is located in interior of vehicle.

Well that sums up the midwest rear. I'd definately go for it since its as light as a 10 bolt but far heavier duty. I've thought that would also be a fun series to be in to bad its so far away.

The good thing about True Street is the ability to run so many different car and engine combinations. Just make sure you figure in a good cooling system, traction for the worst possible outings (running three laps with little to no track prep in-between runs will expose a subpar suspension quickly), and plenty of power! It's a fun time, I ran the class at Bradenton this year.
Good luck!
