I've been searching all around the internet and all of this forum and cant find a thread that explains the differences in between the true street class and the sfwd class. And if there the same just call me a jackass lol. But other than that i'd like to know the differences and qualifications and rules for both classes. Thanks

 

AFAIK, True Street requires exhaust to have a muffler and exit under the car (no hood exit) and are limited to a 67.9mm turbo. SFWD allows a 72mm turbo, hood exit exhaust, slightly larger tires (25" vs. 24.5"), and the car can be lighter.

True Street Rules

SFWD Rules

Basically if you build a car to True Street rules it can run in SFWD but will probably have a hard time being competitive. A car built to the limit of SFWD rules will be too light and have too large of a turbo to run in True Street.

 

yep^^

 

MIR rules true street exhaust can go anywhere.

Exhaust: Muffler(s) are required unless vehicle is turbocharged. Exhaust may exit anywhere

 

yea depends on where the true street class lives. Might as well go by the northern version.

 

Ok cool thanks for clearing that up guys i was starting to wonder if they were being considered the same class now or what
