Has anyone tried to see if the ZR1 carbon rotors will bolt up to the GT-Rs wheel hubs? I know the bolt spacing is different, but maybe if you separated the disc from the hats? This could be a cheaper option than a 15k CCM upgrade?

Completely different animal from the 15k CCM AP/Stillen brakes. This could be a more expensive option when you have to replace the ZR1 rotors which are many times more fragile than the nearly indestructible AP/Stillen ones.

+1 look at the comparo thats highlighted in this thread http://www.nagtroc.o...mic-brake-kits/
you will notice that the more expensive CC kits are worlds better than the zr1/brembo kits, they are getting refreshes to help any issues that they may have had prior, but price keeps going up.

the problem i see with the gtr brakes is the heat and needing to cool the brakes down. the pads will last longer if you keep the rotors cooler which is hard to do on this car. there is no perfect brake cooling setup on the R35 yet got a thread with some info tho http://www.nagtroc.o...g-new-for-2010/

regardless i think it would be great to get some R&D on the zr1 brakes for the gtr. i think someone suggested it wont work, i cant confirm that.

Where do you source your ZR-1 rotors?

I had to do some modifications:
- new bells for the rear discs
- modification to front and rear back plates

The front disc are Ferrari California disc, only mod to make them fit is the diameter of the centre hole.
ZR1 disc will also fit. but you have to modify the calipers to fit the wider discs (36mm)

Weight saving is about 7kg (15.5lbs) at each rear corner and 5.5kg (12lbs) at each front corner

Interesting stuff... I wonder how cost-effective this would be on our cars.

I've read the OEM carbon ceramic rotors simply won't hold up on the track and that some ZR-1 owners who have used them on the track had some issues doing such... That's what I read anyway...

Amazing - but what are we looking at? Are these the Spec V calipers and the ZR1 discs?

Ferrari California disc & OEM caliper painted correct? The disk is 390mm just like the 12 & 13 disk I believe.

Make sure everybody notes that these are the SpecV Calipers. Because the SpecV rotor is bigger than the stockers, we KNOW that the either the caliper or the knuckle on the SpecV is different (and the general consensus is that is likely the caliper).

You will either need the SpecV caliper or a spacer to make this work.

I've heard of people going through pads but not many rotors

Wik:
The front brake rotors are similar carbon ceramic design as those employed in the Ferrari FXX track car, the difference being a diameter reduction from 15.75 in (400 mm) to 15.5 in (390 mm) for added wheel clearance. The front calipers are Brembo 6-piston units.
Rear calipers are Brembo 4-piston units. The rear brakes are 15 in (380 mm) carbon ceramic rotors, originally employed as the Enzo Ferrari's front rotors. Same as those used in the BMW M3 GTS.

Both front and rear pads have twice the contact area of the Z06's, as well as the addition of brake pad wear sensors. The brake master cylinder, booster, ABS unit and system controller are now sourced from Bosch in place of Delphi.

As a result, the ZR1 will stop from 60 mph (97 km/h) in a current production car record breaking 96 feet (29.3 m).

So its not actually ZR1 Brakes?... I was expecting to see ZR1 calipers and ZR1 rotors?

Unless all these cars use common rotors and different calipers.
