Update on the brake pads...
My contact at Euro Car Parts has confirmed that the BMW fitment pad is the identical one to the 3200/4200 pad being sold by brakeparts.co.uk However, legally the aren't allowed to sell them for fitment to a car other than the model that they have the Reg 90 approval for (which makes them road legal).
Though if you order them online, no one knows what car you have or plan to fit them to...
Technically I guess it could affect insurance/warranty claims, but unless the claim arose from brake failure then IMO I'm not sure than any claims inspector would ever check what brake pads were fitted..?
So, Textar front brake pads for 3200/4200/GS for £63 a pair. Or less right now seeing as Euro Car Parts are offering 25% off all online brake part orders at the moment...
