Help! After waiting weeks, my new Ferodo brake pads arrived in time for my 1st DE day of the year (this coming Thursday). I went to change them on Saturday to bed them in, and discovered they sent me 993 pads! The 993 rear ones will fit my front calipers, but obviously not my rears. These calipers are the single pair piston ones that were replaced in the 92 model. My Ferodo contact is apologetic and is scambling around trying to find the right sized pad for me, but cannot find the part #. I checked locally at a Hawk dealer, so we could use the # to cross reference the right Ferodo part, but their info is incorrect: they list the part as HB170 and that it can go on front or rear ie it's basically the front pad that can on the rear of a 993. I can understand why the dealer made the mistake.

What I need is the part # for *any* after market rear pad for a '91 964--Ferodo would be ideal, but once we have the # of another manufacturer we can track down the right part.

Another question: if I can't find the pad in time, is it wise to run with race pads just in the front? It would obviously bias the brakes to the front and encourage oversteer, but would it be noticable for a track day?

Thanks in advance for any help!

Chris,

This isn't exactly what you asked for, but the Porsche part no. is 964 352 949 01 for the double piston rear brakes. It's 964 351 939 02 for the 4 piston brakes (same brake pads front and rear on 4 piston brakes). Perhaps this extra info will help.

FWIW, I remember reading that it's VERY hard to find an aftermarket brake pad for the double piston rear brakes on a 964. You may have to find a manufacturer that you can send your old backing plates to so that they can put their brake compound on it.

Good luck!
Drew 92 C2

If you can't put matched rears on, I'd recommend street pads all around.

Chris, the track pads on the front with "regulars" on the rear won't cause oversteer whatsoever...what it MIGHT cause is for your ABS to work overtime IF you're into threshold braking.

MY best guess is that you're NOT??

What I mean is that is you're quite aggressive with your breaking, of course, your fronts will have more "grab" than the rear, causing potential lockup in which your ABS will kick in. The other possible "sensation" you may experience is the rear end swaying a bit as it won't brake as hard as the front.

These are both manageable issues during a track event, especially if you're in the Green or Blue group...if you're Solo or Instructor - well, then you're likely out there with the "hot-shoes" and BETTER have your braking situation under wraps. <img border="0" title="" alt="[Eek!]" src="eek.gif" />

I dunno what group you're in or how much experience you have, but if you're a "green-grouper", go there with what you have.

I have ran track pads up front and "regulars" in the rear at about half the tracks I've ran due to costs and just plain testing out various theories, etc.

Keep in mind I have Big Reds up front, so I've even ran street pads up front and track pads in the rear. Also, keep in mind that I have updated the rear with four-piston calipers from a '93 C2.

The "regular" pads last MUCH longer than the agressive compounds and cost half as much.

Pagid, Hawk and I believe even Carbotech carry pads for the rear of a '90/'91 C2.

Have fun at your first track day of 2003...and KTRSD!! (Keep the Rubber Side Down!) <img border="0" alt="[burnout]" title="" src="graemlins/burnout.gif" />
