Nope, these am STD Audi/Brembo/Pagid OE pads. The RS3 (and TTRS) did have an upgrade (47i6) but it's primary aim was to reduce low-speed brake squeal and while the back-plate of the brake pad was modified the pad-to-backplate 'fixings' remained the same and as mine have already started to score the brake disc, and they didn't resolve the low-speed brake squeal. Most RS3 owners will know that I've spent a long time with this issue corresponding with dealers, Audi UK, and Audi GmbH, and having evaluated a number of brake-pad alternatives am ow running EBC Redstuff front and rear on my RS3. That said, Redstuff did NOT suit our TT so that's on OE pads and all's well. Our A2 is on EBC Greenstuff and that stops very well.
Enjoy that Westfield; I was invited to manage the factory but with the owner and every member of the family in daily attendance and each carrying their own particular Westfield ball thought better of it.
