Difrance between MWM and USRA B-Mod

[Brayten#4]

What are the difrances between a Midwest modified and a usra b-mod. Iv seen a guy race both with the same car just not on the same night. and yes im sure its the same car. I do know he was one that was chosen to test a crate in MWM. Just curious to what changes he has to make when switching from MWM to USRA B-MOD besides tires. Thanks

I think a trailing arm rule of 5* split left to right is in place for MWM. Not sure USRA rules. Also MWM have sliders I've seen but don't know if USRA you can or not.

Anybody else have some info?? Thanks

Just read the rules I think would be best bud. I know of some MWM runnning sliders on the trailing arms and USRA I don't think you can. I think trans rules for MWM are in affect too for certain trannys.
