968 M030 brake cooling kit
Does anyone know the part number for the 968 M030 brake cooling kit? I haven't been able to find it in PET or at our local Porsche parts counter. Any help would be appreciated. Following on a recent thread, I'm thinking of scrapping my Cool Brake kit and going to the above.

Smokey, is the M030 different from the standard 968 brake cooling kit? I dunno if there are part numbers on the parts, but I can probably find time to look at the actual parts this week end if it's the same.
My non-M030 968 ('94) has a plastic scoop on the front edge of each a-arm that picks air up from under the car, and sends it up to another plastic piece that mounts to the strut housing... this directs the air into the back center of the rotor.
FWIW, if this is what you're looking for, I think you'll have to do some clever fabrication to mount it on a '44 (or buy 968 a-arms & struts...$$$). Both the a-arm & strut have features for mounting these parts that I'm pretty sure aren't on the similar 944/951 parts.

I actually bought a set of 968 brake cooling ducts (they are on all 968s) with an adapter kit to fit 944 turbo. I forgot where I got them ... but the adapter looks very easy to make.

Don't know the part number either but you can get them directly from Diversified Cryogenics. Talk to Bill Groschen.

Thanks for the input, sorry about the late response. Been away. What I was thinking of was the standard 968 cooling kit, and from all appearances, it requires modifications to the a-arms. I have Blazcak short steel a-arms, so I'm not trying the 968 kit now. I think the Cool Brake kit I have doesn't help much due to the serpentine tubing, and I'm going back to the original '86 951 ducting and deflector. As I go faster, the brakes seem to get worse. At Watkins Glen with the White and Black run group, I got about two laps before I got major fade and had to back off. I'm running Hawk HP Plus, so the next step is racing pads. Or stick to Mosport, where you brake much less.
Currently, I have S4's on the front and standard 951 back brakes. I'm thinking of putting back the front 951 calipers at the back to get more work from the back brakes - but not too much. I have a 33 proportioning valve, and the other option is to go to the 55(?) valve.
First, I'll see how the standard ducting works compared to the Cool Brake kit. Again, thanks for the suggestions and info.

Smokey.
You are fine with the 5/33 bar bias regulator
(S4 front and stock 951 raer)
5/55 would be too much.
With your brake set up. S4 front and stock 951 rear, you should be in good shape. even without additional cooling kit. (it certainly helps)
Sounds like the problem is not the brakes but the pads. Hawk HP pads are not up to your speed and braking. You should be able to go Full Blast for an entire 20-30 minutes session at the Glen with
good pads.

Eugene, thanks. I think I'll just change one thing at a time, so my next step will be the standard cooling ducts. Scientific method, and all that. Next, some racing brake pads. I'm thinking of Hawk Blues, but I've also heard some very positive things about Ferodo 2500's. Has anyone used those on the track?

Smokey, yep, the 968 A-arm has a tab on the front edge with a drilled & tapped hole (even with the sway bar hole), and a boss near the ball joint w. a drilled & tapped hole. You'd need these or a substitute for them to mount the lower half of the 968 scoops. I don't think the 944 / 951 arms have either of these features.
As I recall it, there's also a bracket (or two) on the lower end of the strut housing for the upper half of the scoop.
Jim, back to class.... "work"...hah!

Eugene, my mechanic says he has mounted the S2/968 cooling vanes on the older a-arms by drilling and tapping a few holes. One of the mounting holes is in front of the a-arm on that little bracket I don't have, so it probably requires an adapter of some sort. I'm going to try the standard 951 aluminum deflector and duct, and then if I still need more cooling, to add the 968 scoop. My test will be the entry to turn 8 at Mosport next weekend, slowing from 130 to 90 after the crest.
