Need some new brake discs for my B5.5 with 312mm upgrade.
GSF have two types of 312mm x 25mm discs - overall height 49.9mm vs 46.5mm and 65mm centering diameter vs 68mm
Which do I need please?

On GSF I cant use my reg plate as it doesn't think I have the upgrade, but ECP seem to say I need the 46.5mm /68mm items as it does list the 312mm option
