Anyone have one of these fitted?
 

Hamicad seems to be the popular option here and will actually cost you £1 less delivered to your door.

i just bought one for my k4 and they look great. a real bugger to fit. so be warned. hamicad.co.uk

Fitted one 10 months ago, no probs, good durable finish, looks great and it hasn't fallen off or cracked. Added a couple of small PK screws to keep the original undertray a tight fit to the t.tidy. This was only necessary because the undertray had been deformed by incorrect fitting (by the main dealer)into the fender reccess following a repair.

Just had a look at the Hamicad item, IMHO this unit is much neater as there are no protruding lumps of back (metal?) to spoil the lines of the r send.
