D.8.c. No part of the car, except for the exhaust system and suspension components, shall be lower than the lowest part of the wheel rims.

I read this to mean that chasis rails can not be lower than the lowest part of the wheel rims.

I had not made the connection that this could pose an additional limitation to the 5" ride height rule. I need to go back and measure mine as I could see this occuring while still meeting the 5" ride height rule. I had only checked ride height and made no measurements with regards to this rule previously.

Continually coming to realizations of what the rules mean to my car's preparation.
