I have a 1973 914/6 conversion with 2.4 L engine(being rebuilt now), and I am running the Alloy "S" brake calipers up front. I am looking to upgrade the front brakes. Boxster calipers are cheaper than the Big reds and a bit smaller as I would like to run a 17" wheel or smaller.
Anyone have the boxster calipers installed? Which rotors did you use? Adapters? I have an old set of Bremtek calipers that I might use if I can find some seal kits for them still. New to these forums, but love all the stuff on this site...especially all the racing pics |

"Upgrade" in regard to 914 brakes is bandied about quite a bit, here's my take on it.
Real upgrades actually consist of increasing the heat sink and/or cooling capicity of the brakes. Another is increasing the mechanical advantage of the rotor vs the wheel/tire. The former is straight forward by adding a vented and/ or thicker rotor. The latter is a bit tougher. You need a larger diameter rotor, a caliper with more clamping force/pad area, bigger wheels, a larger master cylinder. Both of these add weight.....and the worst kinds, unsprung and maybe rotational weight. If you track your car and have you've turned your 914 into a 2500 lb sled some of the above is a good plan. The original poster needs none of this, IMO. The S caliper set up is light/vented/ and designed to stop a 300-400lb heavier car repeatedly. The soft pedal ever allows better modulation of the brakes. (IMG:style_emoticons/default/biggrin.gif) If you're tracking it the most I would do would be to add some racing pads.....but those suck for the street. Big wheels have a similar weight problem. I use the S set up also. Works for me. Attached thumbnail(s)
