Hi All,

No doubt everyone will be interested to see some photos we've just received in the last few days from Project Mu in Japan, of Project Mu's new replacement brake disk rotors for the R35.

It's a very neat setup for use with the factory calipers, with disks the same size as the factory disks. The disks bolt to the car using the factory brake hat and fasteners.

They can also be bolted to the car using a custom hat as shown in the photo at the top of this post.

How is the performance of the disks, they look a little basic, no slots....can understand the no cross drill but no slots.

On a car like the R35 I would do away with the cross drilling but definately keep the slotted rotors....any ideas on why this design was chosen?

Slots optional?

Hi Gibbo,

The photos were sent from Project Mu in Japan and are of the unslotted version - a slotted version is also available and the version with slots is what will be supplied in Australia.

Though the unslotted versions do not look as high tech as the slotted versions, they are the same casting used in both the slotted and unslotted versions, and they are a very serious advanced design disk - more info on the design is below.

The unslotted versions of these disks are run by some teams in Japan, but the Australian market demands the slotted versions as the slots help clear gases under use etc.

So the ones supplied to Australian customers are the version with slots.

Designwise, the Project Mu replacement disks for the R35 GT-R are Project Mu original castings from Project Mu's 380 mm Big Brake Kit (photo above), with different mounting details to allow them to be attached to the factory R35 GT-R brake hat.

So they are an advanced design, curved vane, 48 vane disk. They have an advanced core vane design resulting in very high heat transfer qualities. The slotted version have 8 slots in the rotor surface.

The performance of the 380mm disks used in Project Mu's 380 mm Big Brake Kit is very good indeed - as mentioned above the R35 replacement disks use the same Project Mu original disk castings as in the 380 mm big brake kit, with different mounting details to suit the R35 GT-R.

You can find more info about the Project Mu Replacement Brake Disks / Rotors for the R35 GT-R here - they are available now ...
