944 rear brakes
I have a set of early 944 rear brakes and I want to up grade from the single piston calipers to 4 pot calipers. Does anyone have an idea if that is possible? The rotors I have are 289mm by 20mm I was told that these are not wide enough to use brembos. Is there a rear rotor that I can use with the early hub and still retain the e brake?

You will need the rear rotor from a 944 turbo (299mm x 24mm) as well as the matching 4 piston brembo caliper.
You will be using factory Porsche parts so you will be able to retain the ebrake assembly. Hope this helps. Sandeep

I am using the 20mm thick 944 discs with 968 4 pot brembo's. I will space the calipers out so they sit central over the disc, meaning I will have an extra 2mm gap on each brake pad. I am assuming that as long as I keep the pads & discs in good condition & don't let them wear down excessivly this will be OK.
I know others have done the same as me. IS this OK? Anyone running on the road have any feedback? Or should I go with the turbo rear discs too? (my front end is using early discs with brembos because the late discs are too big diameter)

That will work but you must keep an eye on pad wear, for if the pad gets too thin, there is danger of the pad falling out.
For safety's sake, get the proper rotor to go with the caliper. Sandeep

I had a Porsche shop tell me that the Brembos will stress the thin discs too much and crack them, so go easy on them.

out of interest, are the 24mm thick 944 turbo discs the same as the early ones except being thicker & 10mm larger diameter? Are the offsets etc the same?

Yup. You do not want the pistons falling out of the caliper either.

Hi
Boxster rears use 292mm, 20mm, ventilated rotor, Im using Boxster calipers on my car with 289 x 20 rotors, the Boxster caliper is radial mounted which makes it very easy to adapt. Steve C

Hi
Im getting some Boxster S calipers soon. I have said this before so I hope I dont bore everyone. Im going to get some Boxster S rotors, have a hub made to fit it onto a stock spindle without any track increase and mount the rotors on these. Then I will just have a alloyblock style adaptor made to bolt the caliper to the stock beetle stub axle. Steve C

Hello Steve,
Have you got a list of all the rotor dimensions for the various Porsche models? Alas, they use different bearings and spindles, right? By the way, which part of Down Under are ya at? Sprint.
