Here is my plan...unless someone can make a better argument.
So I now have my billet front hubs, so I am going to be running M calipers with Pagid orange in front. With SC vented rotors. For the rear I can either run stock 4 rears or put the stock 4 fronts on the rear. With mid performance or stock pads. Remove the stock proportioning valve and place a T? or leave proportioning valve? Parking brake will be removed regardless because of roll bar interference with hand brake mechanism. Will be running stock 4 bolt Fuchs with "R" rated tires. So give me your best shots, suggestions etc. (IMG:http://www.914world.com/bbs2/html/emoticons/rolleyes.gif) |

T or adjustable valve. The adjustable one is preferred, because you can fiddle the balance if you find it's got too much rear bias. But, according to a number of other people around here, you shouldn't have too much rear bias...

"T"
Easier to bleed the brake system. Firm petal. Set bias with brake pads. Also go to 19mm master cylinder. Ken |

Too much rear brake. Porsche didn't go with that much brake on the rear (42mm pistons) until 1984. They coupled it with 48mm front pistons at that time (and a first for a 911... a p-valve).
I would use: M-Calipers up front as stated. 19mm MC as stated. Leave the P-Valve in place "Narrow" Rear M-calipers with 38mm pistons (off a 68-69 911 or later ones, 70-83 with the spacer removed) on the rear. This would give you the exact same configuration as a 914-6 (w/o the parking brake of course) |
