okay...for a factory 914 /4, the front calipers (piston area wise) are 1.61 larger than the rear....(42mm and 33mm)
for early 911's (up to '84), the fronts are 1.6 larger from '84 to '89, the fronts are only 1.3 times larger than the rears....then the ratios vary from 1.4 to 1.7 until the arrival of the 1st Twin-turbo, that car has calipers that have piston areas 2X the size of the rears !!!!! I'm just wondering what combo people have successfully ran.....it's interesting to note that the standard Boxster front calipers if bolted to the front of a 911, the Boxster piston area is only 1.05 larger than the standard 911 fronts.....seems like a darn near equal swap, except for the bigger pads you get with the Boxster calipers (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) |
