GiroDisc 380 mm high-performance brake discs (2-piece) for Dodge Durango 6.4 SRT and Jeep Grand Cherokee 6.4 SRT

The 380 mm GiroDisc "Demon Performance" brake discs are a direct replacement for the original brake discs of Jeep Grand Cherokee SRT from 2011 and Durango SRT both with the one-piece brake disc from the factory and with the 2-piece performance brake discs. No modifications are necessary.
The front brake discs weigh 10.6 kg each compared to 15 kg for the original ones.
This reduction in rotating and unsprung weight by around 4 kg per wheel enables faster acceleration and better chassis response.

The center section of the brake disc is made from 6061-T6 aircraft aluminum, which is sourced exclusively from the USA.
The disc is made from cast iron, cast in the USA and machined from start to finish specifically for GiroDisc.
The brake discs have a curved wing design that was developed in racing and acts as a centrifugal pump to push cooling air through the discs.

The friction rings and the cup are mounted on floating bearings, using 12 high-strength threaded bolts that have been cadmium-plated for long-lasting corrosion resistance. These bolts take the load of the braking operations while maintaining the axial and radial clearance between the cup and the friction ring.
The bolts are fastened with grade 12 bolts and hardened washers. To prevent the brake discs from making noise when cold, they are mounted with noise-dampening spring washers on the rotor side, which allow the brake disc to expand when heated, but prevent the rattling and noise associated with floating brake discs. This floating mounting also allows the brake disc to center itself between the pads.

If the GiroDisc brake discs need to be replaced due to wear, this does not require completely new brake discs.
It is sufficient to replace the friction ring, which is available separately. This reduces the cost of brake wear in the long term.
