I can't say for sure Paul but if you have used your registration or vehicle details for finding the pads then those should be the ones. Eurocarparts are usually pretty good at that sort of thing.
Might be worth trying some of the traders on here though like; The Cougar Store, Torqen, Tarmac Sportz, Clark Motorsports etc as they're usually pretty good on prices. Just send them a PM (private message).
Clark Motorsports for example seem to be cheaper on OEM Brembo front pads providing they're the same: http://www.clarkmotorsport.net/website/webshop/productsSearch.asp?searchBrand=Brembo
