SportsMaserati.com is now organising a third group buy for brake discs. Hundreds of these discs have now been fitted to members' cars, all with very positive reports. Respected independents including Autoshield and Emblem have praised the quality of the discs and happily fitted them to customers' cars.
The discs are for the 3200/4200/Spyder and GranSport as well as Ferrari 456 and 550. They are manufactured to a high specification (see below) - GG15HC grade casting, vented, cross-drilled with countersunk holes (same hole pattern as the 550). GG15HC is a higher grade casting than OEM.
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 have gone through a full development programme, are fully balanced and the hubs and outside perimeter are covered in a black corrosion-resistant coating.
All discs will carry a full manufacturers warranty.

PRICES
Front discs
£55 +VAT each
Rear discs
