ALC Front Brake Kits - Alcon 2009+ Nissan GT-R R35 412x36mm Rotor 6 Piston Caliper RC6 Front Axle Kit - Sky Blue

The factory Brembo brakes on a Nissan GT-R (R35) do a respectable job for everyday street use, but the R35 is a heavy car. When you start throwing serious horsepower at the VR38DETT engine and hitting a road course, the stock front brakes get hammered by extreme heat almost instantly. Under repeated hard deceleration from high track speeds, the stock front rotors quickly develop stress cracks, the pedal gets alarmingly soft, and brake fade kicks in hard. The ALC Front Brake Kit featuring Alcon's massive RC6 front axle system (Part Number: BKF7059ZG05) completely cures these high-heat track issues. This kit swaps out your tired front setup for a massive pair of 6-piston forged aluminum calipers finished in an eye-catching Sky Blue paint, running massive 412x36mm two-piece high-friction rotors.Alcon builds this front system specifically to survive the heavy weight and high speeds of the GT-R platform. The RC6 caliper is forged from high-strength aluminum in a two-piece design that completely eliminates structural body flex when you slam the brake pedal down hard. Instead of standard steel pistons that transfer intense heat straight into your fluid, this system uses staggered stainless steel pistons that act as a thermal barrier. This configuration keeps your brake fluid significantly cooler, preventing a spongy pedal feel during long track sessions. The massive 412mm rotors drastically increase the surface area available to dissipate heat, allowing your performance brake pads to maintain flat, uniform contact for brutal stopping power every single time.

Features and Benefits

Forged 6-Piston RC6 Calipers

These high-strength calipers are forged from premium aerospace-grade aluminum to resist structural twisting under extreme clamping forces. The ultra-stiff caliper housing provides a highly precise, immediate pedal bite that gives you total confidence when braking deep into corners.

Massive 412x36mm Two-Piece Rotors

The oversized two-piece rotor configuration separates the lightweight aluminum inner hat from the outer iron friction ring. This setup allows the heavy-duty disc to expand naturally under intense thermal stress, preventing the severe rotor warping and steering wheel shake common on track-driven R35s.

Staggered Stainless Steel Pistons

The internal pistons are constructed from premium stainless steel to insulate your hydraulic fluid against high brake pad temperatures. Their staggered sizes prevent uneven pad taper and wear, maximizing the life of your friction material.

High-Temperature Motorsport Internal Seals

The calipers are built with specialized internal pressure seals derived straight from professional motorsport. These seals handle extreme racing temperatures without degrading, drying out, or leaking fluid like standard street boots.

Pin-Mounted Pad Quick-Change System

The calipers use a race-proven pin-mounted pad configuration that makes trackside maintenance incredibly quick. You can swap out worn track pads for street pads in a matter of minutes without unbolting the calipers from the front hub assembly.

Vehicle Fitment Matrix

This premium front-axle big brake system is engineered as a direct high-performance upgrade for the following sports car platform:
Year RangeVehicle MakeChassis ModelDrivetrain Group
2009 – 2026NissanGT-R (R35 Platform)3.8L V6 Twin-Turbo (AWD) (Front Axle Only)
Critical Wheel Clearance and Barrel Note: Because this kit upgrades your front setup to massive 412mm rotors and wide 6-piston RC6 calipers, wheel clearance is tight. While this kit is designed to fit under many aggressive 18-inch track wheel setups and most factory 20-inch wheels, variations in wheel barrel shape and spoke profiles can cause contact. We highly recommend checking your specific wheel spoke clearance template or using high-quality hub-centric spacers to maintain a safe operating distance between the caliper body and the wheel spokes.

Frequently Asked Questions (FAQ)

Will this massive 6-piston kit throw off my GT-R’s factory front-to-rear brake bias?
No, it won't. Alcon specifically engineers the internal piston bore sizing of the RC6 caliper to work in perfect harmony with the factory Nissan GT-R master cylinder and rear brake bias setup. The total hydraulic volume matches the factory brake system parameters perfectly, meaning your factory ABS and vehicle dynamic stability control systems will continue to function exactly as intended.
What is the advantage of using stainless steel pistons instead of standard aluminum ones?
Aluminum transfers heat incredibly fast, which means the extreme heat generated by your brake pads during track driving travels straight into your brake fluid, causing the fluid to boil and your pedal to go completely soft. Stainless steel has a much lower rate of thermal conductivity. By using stainless steel for the pistons, Alcon creates a highly effective thermal barrier that keeps your brake fluid cool and your pedal firm.
Can I run this front big brake kit with my stock factory rear brakes?
Yes, you can absolutely run this kit on the front axle while keeping your stock factory rear brakes. Because the system is engineered to preserve proper factory brake bias, it integrates smoothly with the stock rear setup. However, for maximum balanced performance on a road course, we eventually recommend matching this kit with a set of upgraded rear pads and high-carbon rotors to handle the overall increased stopping capacity.
