Uprated 2-Part Brake Fixed Discs for Alcon Brakes (Pair)
Uprated 2-Part fixed discs to use with the Alcon brake set up on the Ariel Atom made of a hard anodised bell and a vented and race-grooved cast iron disc with a surface grind finish. The discs can be fitted to the front or the rear of the car and come as a pair (2 discs - Left+Right).
Two part discs offer several advantages over standard ones. As the centre part (bell) is made of lightweight aluminium as opposed to cast iron on traditional discs, the overall weight can be significantly less than a one-part equivalent.
The heat management is also better. The two-piece design lends itself to doing the whole job of a brake disc better. As the bell is not part of the rotor itself, when the rotor gets hot the heat transfer to the bell is not as great. So instead of the disc being one big piece of cast iron that retains the heat build-up over time, the rotor itself deals with the heat management whilst the bell itself can just do its own job of holding everything together.
The overall cost of ownership is also reduced. Although the initial investment may be higher, when the rotor wears out it can be replaced at a much lower cost. The bell will last a long time and the bolts normally last 5 or more rotor changes.
The bells on all Skunkwurx two-part discs are made with hard anodised aluminium which prevents it from rusting or fading from heat/light. The rotors are interchangeable. So a fully-floating disc may at a later date be converted in to a fixed two-part disc or vice versa.
The discs can be used both on the front and the rear, and on the front only for the cars with the competition or standard brakes at the rear.
Weight of asembled brake disc: Approx 4.5kg
These discs are direct replacements for the OEM Alcon discs and can be fitted without any modifications, as per normal disc installation.
