[diamond geezer]

im having 4 pot willwoods fitted soon, and was wondering if there is a way aftermarket or other wise to improve pedal feel. is there a way to upgrade or uprate the williams master cylinder?

thanks

worth looking at models with 4-pots as standard to check for interchangeablity (wow made up word?!?! lol ) megane 225???
