closed the deal last night for 2 pairs of 4-piston calipers for $200....designed for 22mm rotors, but I see no reason why they won't be okay with the 911 20mm rotors...now to go break into someones garage and get a pair of the billet 4-lug hubs
now back to the rotors.....PP has the fronts for $48 and the rears are $72 each...I guess one good thing is that one normally goes thru front rotors faster than rear rotors...we shall see.... |

Mike, the 20mm rotor will be fine with a 22mm capable caliper.

because while the fronts are relatively shallow, and bolt to the hub, the rears are fairly deep, and incorporate a fairly thick and concentrically machined brake drum for the parking / e-brake.
i think i'd take advantage of the thickness differential to run some of those titanium pad insulators, but that's just me. 911 rear brakes have the "opportunity" to do a bigger share of the work since the back is already a lot heavier to start with ... |

my 964 front brakes rotors are designed just like the rears with the deep offset hubs....you can hardly tell the difference between the 2 just sitting on the workbench (I've only had new rotors and pads for 1 year...just too lazy to change them (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif) ) |

thanks Paul....
speaking of rear rotors.....someone made a big-brake kit using 930 rear rotors on the front.....heavier than using an aluminum hat bolted up to a rotor, but less parts to deal with and simpler..... |

I actually found them cheaper at El Auto Parts I just didn't look down the screen far enough. (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif) $49.68 each with free ground shipping for orders over $50. But, if you want them you better hurry. A quick look direct into WorldPac inventory only shows two in stock. |

i thought we were talking about 914-compatible 911 vented rear disks ... anyway, the point is the same - there's an additional machining step, and it occurs not only in a different plane, but it must be concentric with the hub centerline. |
