Hard driving in an R33 GT-R quickly shows where the factory hardware begins to struggle, especially during longer stints. The Endless Racing Big 4 Rear Performance Brake System fills that gap with a package engineered for stability and precision. This kit elevates R33 Skyline brakes with forged aluminum construction, larger diameter rotors, and pad compounds shaped by real motorsport development.
Endless tuned this system to work cleanly with its 12POT and 6POT front calipers, creating four wheel balance that feels natural on circuit entries, mid-corner, and corner exit stabilization. Drivers who cycle between street, touge, and track days will appreciate the consistent release, direct pedal feedback, and the way the brakes stay predictable as heat climbs.
A rear caliper takes a beating during repeated laps, but strength matters more than size alone. Endless builds the Big 4 calipers from forged aluminum, a material that keeps rigidity high without adding unnecessary weight. At 3486 grams, the caliper body stays compact yet strong, holding its shape under load so the R33 Skyline brakes deliver the same consistent response every time the pedal drops.
The anodized blue finish does more than complete the look. Anodizing creates a hardened surface that resists abrasion, corrosion, and heat far better than paint or powder coat, which is crucial on hardware constantly exposed to brake dust, debris, and elevated temperatures. Each kit includes pad compounds such as SSM, TR, MX72, and MX72PLUS, giving drivers options that match their preferred heat range, bite, and durability.
Rotor compatibility spans 355 to 370 mm, and the system fits most 17-inch wheels, though actual clearance depends on wheel brand and barrel design. With calipers this wide and robust, wheel selection becomes an important part of dialing in the ideal R33 Skyline brakes setup.
Rotor tech is where Endless separates itself. These R33 Skyline brakes use the company’s E Slit design, a combination of long curved slots and smaller E-shaped slits across the rotor face. The curved slit gently reshapes the pad surface to prevent glazing, while the E-slits raise friction and reinforce bite. As the long slit wears away, the floating E pattern becomes a visible indicator that replacement is due.
The rotors are built from a special carbon steel blend unique to Endless. This material resists heat cracking, keeps friction levels stable, and handles temperature swings more gracefully than typical cast steel. Each rotor also undergoes a heat treatment that stabilizes the internal structure before it ever sees a car. That step reduces the formation of heat cracks, helps the disc expand more uniformly, and lengthens rotor life.
A blue-painted bell hat finish ties the styling back to the calipers and adds corrosion protection, which helps the rotors maintain a clean appearance on exposed R33 Skyline brakes.
Endless emphasizes bedding because it directly affects performance at temperature. New pads and rotors should be gradually brought up to roughly 400–500°C through firm but not extreme braking. After reaching temp, the system should be allowed to cool naturally to about 100°C. This process stabilizes the pad surface, reduces uneven transfer, and sets the brakes up for consistent response.
Dry weather is recommended. Bedding in the rain can prevent pads from properly forming their transfer layer, which affects performance during hard driving.
