I realized that about your pic, but can't a dual caliper setup work well sometimes? I know that for moderate track 911s caliper piston pressure is far from the limiting factor, but what about the 956s or 962s that had dual calipers?

No, the issue w/ brakes is always heat not torque

Anyway I guess there was something about the picture that made the rotors look odd.

It appears that they are the 951 352 041 91 rotors & Hopefully the smaller caliper in my picture above. There are several versions of the small caliper, 993 rear 30/34 version is best for that app.

Makes sense in my experience, but I wonder why (some?) 956es had dual calipers? I think they had moved away from it by the 962. I tried to find a photo of the dual caliper setup but didn't have luck.

You're probably thinking of clam shell coolers like this

geez, I saw a big Benz or something recently with a dual caliper front setup...

There were some experiments, decades ago like this 908

But again unsuccesfull from a packaging(they are hard to find room to mount) and thermal management perspective

Some cars use a separate caliper for parking brake, like Carrera GT

But a line lock for the existing caliper is easier and lighter.

Yup. I think it is the S65 AMG... I'll try and dig up some more info.

Maybe not... the are called "Twin sliding Calipers" and it's the CL65 AMG...

"With their filigree spokes, they offer tantalising views of a brake system, the like of which is not to be found in any other manufacturer's products. The system in question is the AMG high-performance brake system which sets new standards for stopping power, sensitivity and resistance to fading.

In keeping with the innovative approach typical of AMG, the front brakes of the CL 65 AMG are equipped with twin sliding calipers. A world first, this new technology combines the advantages of a floating-caliper brake – lower heat transfer to the brake fluid and significantly enhanced comfort as a result of the way the brake pads are located – with the performance of a large fixed-caliper brake."

Sounds like a potential reprise of the Audi UFO fiasco

I'm thinking of a genuine dual caliper setup like that, I would have sworn that they used them some on the 956, but I could be mistaken. In any case, the setup was not successful enough to become popular! Thanks for the info Bill, always interesting to hear from you about brakes :)

this thread gives me wood

Just pictures, Keith is going to have to answer the questions... :)

Aaahhh, what a tease! Give us the scoop off that lap-top you're looking at; tell us about the hp and torque. :eek:

Insane... must subscribe... must....

Keith, any updates?

Fell in love with the Mexico as soon as I saw it!
I've been trying to contact Becker to find out if I can use the navigation here in the US, but they never get back to me. Can you please let us know about the nav? Can it be used in the US? I really want one of these for my Porsche

Yawn... and old thread awakens. :)

Becker never got back to me. After a series of emails and a few phone calls I give up....

The older Becker maps on CD will copy but the format is wrong.

Navteq does the maps for Europe and the US. http://www.navteq.com/

I have not found the right person at Navteq to copy the maps to a CF card in the correct format. If Navteq is listening perfectly happy to pay. :)

As far as the non-audio portion of the build, after an extended pause, car should be off to e-coat soon. Hopefully some updates soon from Keith.

Well, guess I'll go with something like the JVC Kameleon or something that won't throw off my retro interior. Thanks

Would be interesting to hear the Compression ratio and Duration numbers.

Hi,

What kind of ITB's are those?

Thanks,
Dave
