The disks are badly warped on my ST220, so I think it might be time for some new ones. The only question is, what do I buy?

I can't remember the last time I actually had to buy disks and pads for a car, so I'm a bit unsure what to go for. This is only my every day transport, so it won't be doing any track days or anything, so I don't need anything ridiculous.

I've found genuine Ford stuff on fleabay for around £120, which I should imagine would be suitable. However, I was wondering if anyone had any other recommendations?

As I say, I don't need anything extreme, just something that isn't going to warp in no time as the last set did. I may well stump up for the Ford kit, but if anyone has any suggestions of a comparible alternative that might save me a few quid but not sacrifice quality, then I'm all ears!
