Where are the Auto-x car rules ???

There used to be a set of car classification rules that were specific to RMC. I remember them being different than the SCCA's. Am I missing them on the site some where

TIA

I believe RMC now uses SCCA rules when it comes to car classification.

We follow SCCA ruling on all non miatas. We also follow SCCA on miatas except we allow body skirts and any size wheels used by mazda on any year miata to be used in stock.
