Rear Bike Rack for Full Suspension? I have a Giant Warp DS3 and id like to get a rear rack but am struggling to find anything decent &amp; compatible. 
is there such a rack?

You can get racks, what you get will largely depend on the load. The two styles that work are a seat post mount rack or once that clamps to the seat stay. Seatposts often have a low load limit, and can be prone to swinging around, but are generally very popular. Using on on a carbon frame would have to be done with caution - ensure a long seat post insertion.  For heavier loads, a frame mounted rack such as the Thule Pack'n Pedal is best.  

A post rack puts all the extra weight on the rear suspension, so has the advantage its suspended, but you might need to adjust shock settings for an ideal ride. A rear triangle mount is un-suspended weight, and will not affect shock settings as much.
