i havent got abs, mine is a s1 rst (Mk3). i use 5.1 dot fluid. I Use it for road use mainly,may consider taking it on the track.... Why wouldnt it be suitable for the road???? its just i remember reading that the car was designed to be left hand drive and therefore they added the pedal bar etc which has too much flex on it.dont get me wrong,the brakes are good,but i feel i am not gettin FULL force that my brakes could give me!!! Plus i would get the bonus of having a much neater engine bay.
