McLaren Artura Girodisc 390mm Iron Front Rotors Brakes which provide an aerodynamically efficient

which provide an aerodynamically efficient airflow path from the filter to the turbos

The IPD Plenum compliments that power by delivering additional horsepower throughout the entire power band

Power improvements will be fully realized once the factory DME makes all the necessary “adaptation” requirements which occurs after a series of hard pulls on the dyno or full throttle runs (at your local race track of course)

McLaren Artura Girodisc 390mm Iron Front Rotors Brakes which provide an aerodynamically efficientThe Girodisc system is a direct replacement for the OE disc however a different brake pad with an annulus (pad swept area) of 66mm or less must be used. This is done to keep the rotor weight at a reasonable level. If we manufactured a rotor with the same annulus as the OEM CCM rotors they would be unnecessarily heavy. We can provide several different compounds in this shape bases on the customer needs. The central hat section of the disc is made from
