I'm just waiting for Sai to get back to me on this one guys, once I've found part numbers and I know they're right I will list them here and try to get this thread sticky'd.
The correct part number is PFR85-915 for the ibiza beam. Then you just ask for the black compound.
Retail price is 31.62 per side. I think the black compound is 5% more iirc.
