On the HDK, the different.models / versions drop the body over the suspension and motor....it was called channeling in the old days (chopped and chanelled) . This effectively lowers the stance....but with the valuable ground clearance required for a car actually driven. Aside from exhaust clearance, the nutsetter is tucking the wheels/tires in far enough to allow turning without ripping the fenders off.
There are several builds with the different versions on FABO already
Versions are available depending on what you are after....all cost the same as the standard HDK.
Slammer.....-1/2"
Super Slammer......-1"
LA Super Slammer.......-2-1/2"
On my tablet now....I can add links later when I reach the laptop.
