A rotor change (larger diameter) and master cylinder change would likely be required (the 6-piston caliper is going to need a larger bore MC to deliver more fluid volume), but you should still be able to pull of this swap fairly inexpensively if you are already running C5 brakes, and you can definately piece it together from scratch for a reasonable price-- my hunch is you can do it cheaper or on par with a Baer PBR Track kit.

I still can't find the darn thread I read a few days ago; hopefully someone else can dig it up soon. There was a lot of good info in it!

C6 info here and here.

Do the right thing and take them to the track!!

This is our choice of brakes for the ATS track cars:

Those are the AP Racing 6 piston racing calipers, with the full floating 14"x1.50" slotted 2 pc rotor. We are planning on running this on our new tall AFX spindle, as it bolts up with zero mods. The skunk works car gets all our cool new products to get some hard numbers for you guys. The new Baer 6 pot, and the new Zo6 6 pots will also bolt right up to either AFX spindle. Hell, Wilwoods do too. Any brakes from a C5/C6 bolts right up to our new spindles.

This may give you an idea of how large these fockers are in person:

The 1st gen brake market just got more interesting.......

Brake choices
 

Tyler this thread just got taken to a much higher level of need (in my case) Just curious how much would a brake package like that run. Not that I need it I am just wondering.... :hail: :hail:

PM about the price. ATS is an AP Racing dealer, we can hook it up.
Tyler

LOL which one of you is the "model"....clowns! :thumbsup:

Those are siiiiiiiiiiiiiiiiiiiiiiiiiick.

I think I dig the idea of the pieced together ZO6 setup...especially if as said above it can be done for about the same coin as a Baer PBR kit.

So seriously.....there's no wierd funny business required (ie home fab'd brackets) to put the rear on an older rear end housing?

The one above is Shane, the Lead Engineer here @ ATS.

He's actually making fun of me:

I love these brakes. That is a 16" wheel back there.

Bahahahaha! Thats rich!

What is the provision for a parking brake with the ZO6 stuff?

It uses a drum style parking brake that sits inside the 'hat' area of the rear rotor.
Tyler

Tyler I thought you were going to photoshop in larger breasts....man I'm so embarassed! My modeling career is in shambles now thanks a lot.

I love those brakes but don't think they would clear my 17" wheels.

Just like the Eagle Vision TSi and the Intrepid TSi models...

I'd be interested in seeing how large of a brake I can fit behind a 16inch rim... My car won't notice a difference from a 13 inch rotor to a 14 inch, especially when they are cooled correctly!

Hmmm, Now I have to think....

-Matt

They come in 13" diameter too Clint. We can do 13" all the way to 15.5".
Tyler

Matt we currently have Baer's 13" Track kit on our development car with 16 rims. Slight "massaging" of the caliper was required but not much. They sure fill up the rim nice! I will try to post a pic tomorrow from the shop computer.

Someone mentioned the need for a bigger master cyl. to push enough fluid for the larger calipers.
Can anyone identify an appropriate unit for that?
Is there an easy swap candidate?

I have C4 13" inside my Vintage Wheel Works 16" rims using a 1/4" spacer. Get alot of compliments on how it fills the space. Haven't tried any caliper massaging. Tyler - any pics? I'd like to shed the spacers.

No. Unfortunately there is not an easy swap candidate.

The best sizing is different for both, front and rear. The front needs a 7/8" and the rear needs a 1". Bummer that no one makes a cast unit that has differential bore sizing. Now there is an idea for a product.....

Never fear, we have an answer to that too. We have a product on the horizon that will facilitate differentail bore sizing for independant front and rear needs. It will even be bias adjustable........

Rick, Tyler is talking about my 67.... same wheels and same brakes and they still use 3/16" spacers. But they are only needed when the pads are fresh and full thickness.

I am working on that as we speak. The rear package is a differential bore, four piston, 13" set-up. Ill let it out of the bag when I have everything finalized.

Should I just start signing over paychecks to you guys?
