Am goona try a few different setups of rear brakes on my golf. Does anyone know whether you should keep the bias valve matched with the brakes, matched with the car, or are they all the same? Surely if they just measure the angle of the rear suspension arm and adjust brake force appropriately, it doesnt matter what they are connected to.

Let me know wise ones.

If you intend to track it, keep it as close to Factory as possible. When I lowered the 2, the bias shifted rearwards, and I went through a set of tyres through flatspotting without even hearing a squeal or a howl. Stock setup is near perfect for track.
