I need a new M/C. Stock is 17mm, but it seems everyone is selling 19mm. I'll get a firmer pedal and less stroke with the 19mm, correct? Is this good or bad or personal preference?
What are the advantages/disadvantages of both? Thanks! -Jeff ----------- |

Just because, I have a 23mm master cylinder, 914-6 GT rears calipers with drilled and slotted rotors, 88 Carrera front calipers with 24mm drilled and slotted rotors, no proportioning valve, rubber lines at all 4 wheels and I love the way my car brakes. It is a firm pedal and easily modulated. (IMG:style_emoticons/default/beerchug.gif)
