Designed to be a direct replacement for the factory slave cylinder, this setup is a simple bolt in affair. Well as simple as it can be, some of those Audi engine bays can be a bit cramped! Kit will include new stainless steel lines that adapt to factory hard lines where applicable. The bore diameter is the same as the factory bore so you won't notice any pedal difference there. We made the push rod adjustable as well so you can dial in your throw and add a bit more if you want to adjust the pedal engagement and disengagement point.
