The weights were fitted on later 8 pot calipers to help stop the low speed squeal that some people had on the pfl 8v.
They were also fitted on the upgrade 4 pot calipers on the 8P.
I removed mine on both the original 4 pots & the now fitted 8 pots without any noticeable difference.
Dell.
But they are NOT weights but REQUILL tuned absorbers - and 101% useless in this application - mine have stayed on the garage shelf since fitted on 23 Sept 2013 care of Audi UK/Audi GmbH
Better option for the 8P RS3 are these: Ferodo Eco-Friction Green brake pads: https://www.ferodo.co.uk/products/light-vehicles/eco-friction-brake-pads.html
So good for road use I use 'em on my TT, SQ5, AND RS3 with OEM brake discs
Why waste £s trying to solve an issue so few truly understand
Still running my own 8P RS3 since October 2011
