I saw that one too, and the eBay seller is highly praised elsewhere on Club126UK. As to which is "best" depends on what "best" it is you are talking about. The initial price may be the same (actually, at £225 Piotr is 15% cheaper) so one 'best' question is, how easy and pricey will it be to get new discs/pads when the first set wear out ? I don't know the answer to this, but for myself I expect my mileage and demands of braking to be so low that I will wear out long before the brakes do. And with my car being so light, almost ANY disc/pad will be good enough to offer a substantial improvement to the braking (Ladislav reckons it might even be too much improvement!). On the other hand, if you are talking about your Scooby 1800 conversion, then braking efficiency might be a much more pertinent issue, regardless of replacement parts cost and availability. The Bosch discs seem to be plain whilst the Brembos *look* grooved and drilled and so on, so one might presume them to be of higher performance spec. But whether they actually are or not, or whether that grooving is just to make them look sexy, I cannot say.
