I am working on a 5 lug update on the Porsti and trying very hard to avoid going crazy with the brake upgrade at this step. One of the considerations is the abysmal pad selection for the rear callipers. I really like running Hawk HP Plus pads but can't find them for the rear. They are available for the 914-6 rear callipers but the dimensions are slightly different.
914-4 Rear  914-6 Rear  The callipers themselves are almost indistinguishable, is there some extra meat that I could remove from the -4 callipers to make the -6 pads work or could I modify the -6 pads to fit the -4 callipers? Is the pin spacing the same between the callipers? Cheers, Scott |

You're pic is the common 911 rear D31 size. You won't be able to get it to work because of the "pin" locations, not the pad size itself. After all of the grinding and shaving and carcinogenic dust and bits in your lungs, your pins won't line up.
Look for FMSI D30. If you can't find it for 914, look for the following: 1964/64 356 Rear 1965/68 911 Rear All the same. |

Now I am going to have to buy a set of R4-S's from you. Hmmm, I am sensing a conspiracy (IMG:style_emoticons/default/idea.gif) From what I have been able to read about the R4-S compound, the initial bite is not super and they don't squeal like a stuck pig. I like the squealing because people who have no clue think that the car is going to fall apart and stay out of my way and the people who do have a clue tend to give a smirk of acknowledgement (IMG:style_emoticons/default/shades.gif) and stay out of the way. On the plus side they should dust a whole lot less. Cheers, Scott |

My experience has been that the hawks work on heavier cars and are not great on light weight vehicles

It is extraordinary easy to lock up the fronts on the street now. What do you like to use on your 914 and why? |

Amazing rotor wear. Great braking I'm using golds/blues. But for the track |
