Disc hairline cracks... - GT-R Register - Official Nissan Skyline and GTR Owners Club forum

So, couple of questions....

How much of a worry are the hairline cracks that seem common on the OEM discs?

Has anyone succeeded in getting them sorted under warranty?

Can you feel them with a fingernail?

The brakes are a wear item and consumable.

The best bet are aftermarket rotors.

Appreciate they are consumable, but surely there has to a certain performance expectation. Cracking must be a fault, it's not 'wear', it's a failure.

Sounds like running with them is ok, mind you tempted to get some better ones from GTC.

Any claim against the warranty will result in Nissan saying " You have cooled them to quickly" and sight some kind of track action or participation in 30-130 as a full data download will be looked at.

Launch the oem rubbish and go aftermarket. Be aware that even though the pads may look like there is loads left it is not always the case.

All I can say is read and digest the following :
