a little something for the auto-x guys

ok. number 1,i am not building a full honk race car. i have polly bushings in the rear and i can't go lower because the tires will hit without major bodywork. i plan to run firm feel upper arms.
i am about to start on a car for full honk road racing and maybe intimidate some porsches!

Question for wracks71 or autoxcuda steve, speaking of building a full tilt road racing car, what class would you be placed in if someone was running the complete RMS front and rear suspension system? is that like full modified, and is it worth competing in to that extent? please school me.
