Despite plenty of conversation with the dealer and my opting for 16" wheels to add my 17" later not once did bigger brakes enter into the equation. I am not sure if my T5.1 has them and that was specd with 17" but I like the idea of bigger fronts if not rears. So how easy would an upgrade be? Is it simply discs, carriers and callipers or is anything else involved? on the other hand at VW prices that could be silly compared to a decent aftermarket set up. Any thoughts?
