Does anyone know how much you can legally drop the deck per UMP rules. I can't seem to find it anywhere.

G.) The maximum slope/rake of the interior sheet metal “shelf” front-to-rear is 4”-inches when measured
from the firewall to the base of the spoiler. A maximum of 2”-inches of slope/rake will be permitted in front of
the rear of the seat to the firewall and a maximum of 2”-inches of slope/rake will be permitted from the rear
of the seat to the base of the spoiler

hope this helps but i never have seen it checked

2in max is what we have been told been running drop deck for 4yrs. Hood can't contour with deck has to be straight across if its as wide as the car the back of it must be filled in
