Ahl 4 Posted March 14, 2007 The s16 calipers run 54mm pistons, compared to 48mm 205 gti pistons. Some people run them (and the 54mm 307 setup) on the standard M/C and have no problems, though the pedal will be a little longer. Other folks prefer a larger master cylinder to shorten the pedal stroke. I think the favoured one is a 1.8 406 M/C, but you are best to do a search to find this. Theres no reason why you couldn't put it all together as is, and fit a larger M/C later if you feel the need. Share this post Link to post Share on other sites
welshpug 1,657 Posted March 14, 2007 405 uses these calipers with a 22.2mm M/C on the Mi16, but the ZX and 306 use a 23.8mm unit! Share this post Link to post Share on other sites
pug_ham 244 3 Cars Posted March 14, 2007 405 uses these calipers with a 22.2mm M/C on the Mi16, but the ZX and 306 use a 23.8mm unit! 306 S16's use a 22.2mm mc just like the 405. My ZX Haynes doesn't state what size mc they have fitted to any model. Graham. Share this post Link to post Share on other sites
