Why 944?

[markd@mac.com]

I just finished flipping through 11 pages of 944 axle information and I haven't found a nice reason to upgrade. What am I gaining by going for a 944 conversion over stock type 3 IRS with Porsche pattern (5x130) CB Disc Brake conversion? This is on a early swing axle squareback that will be getting a 2056 Type IV conversion with 16" wheels.

There are a number of benifits to the P-car parts over CB's disk brake kit, but the differences may not matter if your plan is to use your Type III as general transport, and not a rice killer, auto-x, or track car.

Stronger forged rear hubs from the 944 vs. the cast steel Roto-Hubs from CB. The 944 stuff includes vented rotors, a little bit better caliper, and you can find it all in a junk yard for low $$$.

Nothing wrong with CB's stuff, just that 944 stuff looks stronger, and was designed for better performance, IMO.

That's kind of what I gathered. Plus a wider track for the wheel conversion. Thanks Yeti. Anyone else have anything to add?

P-parts all the way. More pad surface, vented rotors, thicker pads (less frequent changes), OEM quality vs aftermarket, proper hub center, lighter and sexier.

Also, the price of the P-car stuff will be about equal to the aftermarket.

38mm piston cup in the 944 caliper will give you more rear bias that is very wanted and can really be used in a rear-engined car. You will still not lock-up ever.
And the 944 caliper bracket is a nice alu part!

Look up the piston cup diameter of the CB caliper... Then you will understand

Wally,

What is the rear piston diameter on the CB?

This is a definate benefit as well.
I think those with experience with the subject, know to value this added bonus of the P-rotors with the centering ring at the rear
