For those who can't live without their surfboard, ski's or kayak.  This is a very lightweight, yet solid roof rack system using aluminum crossbars fiberglassed into composite towers.  This rack system simply bolts through to attach to your hardtop. (yes you have to drill 2 holes per rack tower, but the racks can easily be removed and the holes can be capped with paint matched caps for a nearly factory hardtop look.
