I wouldn't discount them fully, they come from the same Taiwanese factory as the XYZ stuff. XYZ brakes are currently fitted to the MD of Brakes International Audi S4, they're also fitted to the "Bora of Win" track car over on uk-mkivs.
The Bora is capable of 15-20 laps back to back of most circuits, on track pads and 32mm wide discs, they are 6 pots.
They're not bad brakes by any means just not designed for the UK climate, they dont have dust seals which on something as hardy as some AP calipers aint a problem but on these things using them as a daily you'de be rebuilding them every 9 months.
Tony Danza's driven the Bora - PM him and ask him what he thinks
