Engines are all stock from the intake all the way to the exhaust manifolds. There are allowances for rebuilding motors to BMW factory specs. Read the Rules carefully about what you can and cannot do during a rebuild. A DME chip is also allowed which helps remove some dangerous lean spots and helps smooth out the power curve at the same time.

The spec exhaust is provided by Mitchum Enterprises. It utilizes part of the OEM exhaust and replaces the catalytic converter back with a two into one pipe and muffler.

Wheels: There isn’t a Spec wheel but there are limits to the specifications of a wheel. The wheel must be a 15×7 and it can’t be any lighter than 15.5 pounds. Some nice options are E30 m3 wheels which bolt right up with no spacer and no hub-centric ring. E34 5 series wheels are also an option but they are not hub-centric.
Tires: From the series inception in 2008 through 2012 the spec tire was a Toyo RA1. Most racers had two sets, a full tread set for the wet/intermediate conditions and a shaved set for the dry. Most racers would cord the tires while many times experiencing the fastest times just before cording. So no need to worry about out heat cycling tires like a hoosier or pure racing slick. Starting in 2013 the new spec tire for the dry will be the Toyo Proxes RR. The Toyo Proxes RA1 may still be used as a wet and intermediate tires. Once racers have experienced the new RRs, info regarding longevity will need to be posted.
