Alcon RC6/RC4 Big Brake Kit – Complete Car Set

This Alcon Big Brake Kit features the latest CAR70 Calipers which are beautifully machined from Forged Alloy and have been optimized for use with the BMW M cars, featuring massive industry leading 400mm X 34mm Alcon front discs and larger 380mm X 32mm rear discs, both with lightweight aluminum bells.

Both front and rear calipers feature staggered pistons in order to ensure even pad wear, the pistons are also made from a proprietary steel, a material known for having exemplary thermal resistance when utilised in braking applications. Other design traits intended to help both calipers weather the extreme temperatures generated by hard braking include unique weatherproof seals, and an internal fluid passage way that negates the need for an external bridging pipe.

As many customer will be looking to use their BMW F-Series M cars on track, the brake kit comes standard with the excellent harder wearing Pagid RS29 pads, and with further pad options available soon. The kit has been enhanced to provide the same performance as the proven Alcon Superkit.

We have tested the Alcon setup on our own BMW M4 and their similar kit on our Nissan GT-R Track Edition. We are really impressed with not just the increased stopping power but also the pedal feel from the brakes.

Caliper Features:

• Front: RC6 (CAR70) – Two piece 6 piston forged caliper Rear: RC4 (CAR69) – Two piece 4 piston forged caliper
• 6 piston design for high stiffness (firm pedal) with low weight
• Piston bore sizes are staggered to ensure even pad wear
• 7% Larger piston area on front calipers and 11% larger pistons area on the rear calipers
• Pin-mounted pads provide low threshold pressure and low noise
• Pads formulated for excellent resistance to fade at elevated temperatures
• Strong cold performance for start up and city driving
• Low noise

Disc Features:

• Front: 400x34mm semi floating disc assembly with “C” grooves and lightweight aluminium bells
• Front disc offers are 9.6% larger disc effective radius which gives an additional 17% increase in available brake torque.
• Rear: 380x32mm semi floating disc assembly with “C” grooves
• 10.6% increase in available brake torque.
• Two piece design featuring aerospace specification alloy bells for high strength with minimum weight
• Discs of unique iron alloy developed by Alcon to provide an optimum combination of bite, thermal stability and durability
• Unique crescent grooves on friction faces provide the bite usually associated with drilled discs without the attendant durability problems
• Directional curved cooling vanes for optimum cooling performance
• Alcon’s floating disc system designed to allow thermal expansion of the disc throughout its life while minimising the tendency to judder

Pagid RS29 pads are for track use only
