Don't forget to price the disks in, these are around 90 + vat each for the solid items from Seat, or 350 + vat!! for the genuine Brembo drilled items.
Pads are not cheap either, well over 100 + vat for the Seat Cupra items or around 90 + vat? for aftermarket items, like ferodo or green/red stuff.
Best to source the complete package imo, with all the things you need including braided hoses. I paid 750+vat for my Brembo GT junior kit, fitted at AmD, but this was a groupbuy price from a few years ago.
