After being asked a couple of questions by potential purchasers, I've checked the spec again with the manufacturer and they're a higher spec casting than initially briefed - the casting is GG15HC, some technical info below

Technical details
GG15HC high silicone, high carbon cast iron alloy as the name implies uses higher carbon content during the casting process; approximately double the carbon content than normal brake discs. Carbon content ranges from 2% to approximately 4% and GG15HC is right at the top end. More silicone is also added to GG15HC to encourage the formation of graphite during the cooling process. These graphite flakes add "Plasticity" to the cast iron matrix and are excellent at absorbing shocks and preventing cracks.

Major advantages of GG15HC cast iron:
- The graphite flakes dampen vibrations, reducing brake judder and brake noise
- The graphite flakes conduct heat very well and therefore reduce thermal distortions
- The graphite flakes act as mini stress "focal points" for potential cracking making this material extremely viable for use on drilled and slotted discs, drawing the stress away from the machined slots or holes, preventing cracks.

The discs will also be fully balanced and hubs covered in a black corrosion-resistant coating.

Pretty good specs there! Like GG15HC that might be better than OEM spec tbh!!

..and if they're black we'll know who's in the forum when we see their cars without recourse to silly stickers on the bumpers.

Maybe if maserati sees this thread they can have an idea on how much money they potentialy loose with their silly consumables pricing

From the perspective of having worked at Volvo for years I Agree with you Jluis.
MAF is doing a great job of utterly detonating the brake disc stupidity. I ask you £500 a pair of discs for a 3200?
So what happens?
People run about on tired old discs ... not safe, not sensible, so well done SportsMaserati and Mark for providing a supply of good new affordable SAFETY devices.

What other bits of Maserati 4200 or 3200 are ridiculously expensive and need regular replacement?
