drop the front end

$470/pr.. wow.
i lowered my front end using the torsion bars, but i only let it down maybe 1.5" and seem to have ocassional problems bottoming out the suspension, and ocassionally will scoop up some gravel with the front of the core support on bumpy gravel roads if im not going slow enough.
i got a piece of gravel jammed in my fan pully on the harmonic balancer one time right after i lowered my car..
