Way Motor Works has the GP2 Belly Pans in stock. We ordered these so long ago that we jumped for joy when we finally got them this week. If your wanting to make the underside of your R55 R56 R57 R58 R59 flat and get some protection for your engine this is the ticket. And being made of a fiber reinforced plastic the GP2 Belly pan is significantly lighter than an aluminum skid plate. I don't have many available so order fast.
