Thanks Wayne!
Here's a mock up of the static ride height on coilovers at ideal height for racing geometry. We're thinking to go another 1" drop in the front since this particular truck likely won't see much racing.
At this height he'll still have full suspension travel and zero worries about frame ground clearance being too little; and no old school cutting of the floor to channel the frame either. Rolling on his 305 mm front tires it'll still clear 30 deg of steering angle too. Wicked!
