Paragon Performance Brake Discs for Jeep Grand Cherokee 6.4 SRT (Front Axle)

Due to the high vehicle weight and the lack of effective brake cooling, premature cracks on the standard brake discs of the Jeep Grand Cherokee SRT are not uncommon after use on the racetrack or under heavy use.
Paragon Performance brake discs can be an effective solution to this problem, while also improving pedal feel and brake control.

The Paragon Performance 2-piece brake disc offers superior braking and cooling efficiency optimised for track use. The directional ventilation fin feature achieves suction and turbulence and directs cool air through the brake disc to improve heat dissipation and increase resistance to cracking under tough track conditions.

The rotor is made of CM-250, a special high carbon cast alloy that ensures optimum bite, thermal properties, high temperature strength and durability.
The rotor rings are heat-treated to relieve stresses in the brake disc and thus prevent deformation and vibration.
They are then turned with a state-of-the-art CBN surface treatment to ensure better running-in with new brake pads.

Vibrations are reduced as the lateral runout of the brake disc is kept within 0.03 mm and the balancing is within 2 grams.
All brake discs have undergone rigorous quality control and testing to ensure that they are fit for purpose.
The two-piece design allows thermal expansion of the brake disc while minimising deformation and ensuring centring of the brake disc to the brake pads.
A slotted brake disc improves braking stability by maintaining a clean contact surface and dissipating the heat and gases generated when the brake pads come into contact with the brake disc.
Slotted brake discs have a decisive advantage over bare brake discs in wet or rainy conditions, as they prevent the formation of water films between the brake pad and the brake disc.
The two-piece Paragon Performance brake discs weigh less than most O.E. brake discs while maintaining thermal load capacity and improve handling by saving unsprung mass.

The aluminium pots are CNC machined from lightweight 6061-T6 aerospace grade aluminium and then hard coated / hard anodised black to provide a non-conductive protective layer. The black hard anodised pots are first hard anodised and then dyed black. They are equivalent in terms of performance/durability.

The black hard coating/hard anodising in accordance with Mil-Spec (MIL-A-8625 Type III) does not discolour in extreme heat. The black hard coating/hard anodised surface is harder, thicker, more wear-resistant and scratch-resistant.

The black hard coat/hard anodised finish provides a thick hard coat that offers greater corrosion resistance and low maintenance durability. A black hardcoat/hard anodised finish holds up better when exposed to ultraviolet (UV) light, which is even more important if the vehicle is frequently parked outdoors.
