Update,
I've had the discs on all round for over a week now, I must say, big improvement in the braking , feels much firmer under the foot and the car pulls up much shorter with the same foot pressure . I can't hear any change in noise what so ever, The stock VW setup is great and very well done, though you don't realize how soft it is until you do the upgrade.

Brakes and sway bars all sorted... now the motor
