Endless Racing Big 4 Rear Performance Brake System w/ 3PC Rotors for E90 BMW 330i & 335i

Endless Racing Big 4 Rear Performance Brake System w/ 3PC Rotors for E90 BMW 330i & 335i

The Endless Racing Big 4 Performance Rear Brake System is a powerful and reliable braking system for any application. Featuring four–piston calipers, oversized rotors, and metallic pads, this system offers exceptional stopping power and fade–free performance. The monoblock calipers are from high–strength aluminum, and are designed to reduce distortion as well as add stiffness while on the track or road. The oversized rotors, paired with the large pads, increase necessary heat dissipation and reduce dreaded brake fade. The Big 4 System also allows for service, allowing pad swaps and caliper rebuilding with a socket and torque wrench, making installation and future maintenance easy and streamlined. This performance brake system is compatible with any 16“ rear wheel, making this system perfect for those who demand responsive and reliable braking performance. A full–scale caliper kit optimally designed for use on circuit roads, featuring increased size to maximize outstanding stopping efficiency. When combined with the 12POT and 6POT front calipers, a balanced and dependable braking experience from all four wheels are achieved. Constructed from forged aluminum, the caliper body is both lightweight and exceptionally rigid. Its outstanding heat tolerance ensures that the durability and performance remain unchanged for prolonged periods of time, even when the caliper is utilized during winding and circuit activity.

Produced with top–of–the–line materials and impeccable designs, Endless‘s calipers are unmatched in quality and retained their accuracy even in tough environments. For maximum performance, pair these calipers with RF650 Racing Super Fluid. You can trust that your brakes will be engaged and disengaged with absolute precision and reliability.

Big 4

• 4POT caliper kit for rear only for full-scale use such as circuit use Big caliper for rear that maximizes the amazing stopping power. Demonstrate reliable stopping power by making the size larger than the conventional rear caliper. In combination with the 12POT or 6POT front caliper, it creates an ideal front-rear braking balance and realizes reliable braking by four wheels. The caliper body is lightweight and highly rigid due to forged aluminum. It also has excellent heat resistance, so it maintains high performance even when used for a long time on circuits and windings.

Blue Anodized Finish

• When exposed to oxygen in the air, aluminum forms a protective layer that prevents further corrosion similar to the rusting process. This process is known as oxidation and is even more complete when anodizing is used to create a harder outer layer of aluminum oxide. Due to its toughness and long–lasting finish, this coating is often used for racing cars instead of painting or powder coating. Anodizing creates an even and strong protective layer that is highly durable.

“E-Slit” Double Shaving Effect

• The impressive design of the E–Slit Rotor derives from the combination of the long slit, which has a soft outline, and the E–Slit which is situated above it. The double shading effect is beneficial to ensure that the pad remains in an ideal state. The long slit on the rotor surface lovingly carves the pad whilst the E–Slit applies strong braking pressure, leading to further enhancement of the braking force. When the long slit disappears and the letter E can be seen clearly, it‘s time to replace the rotor.
• It is advised to change the brake rotor at least every two years even if it seems to be in good condition, as it can deteriorate over time with wear and corrosion such as rust.

E-Slit

• The E–Slit rotor comprises of a curved slit accompanied by four smaller E–Slits. The long slit helps deliver a closer shave to the brake pad, and the E–Slits help to maximize friction, thus maintaining an optimum brake pad condition constantly. It has a carbon blend comprising of a special technology created by Endless that aids in sustaining a consistent mu–level, diminishes heat cracks and maximizes the performance of the brake pad. The slits are designed to yield an ideal shave.

Cost Effective, and More On So Many Levels

• Drivers and racing teams often opt for Endless steel discs for their cost–effectiveness and selection of performance features. In addition, many individuals favor the experience and characteristics Endless steel discs offer.

Special Heat Treatment Process

• The continual and vigorous use of the rotor can generate surface heating and an incremental decrease in size, forming what are known as heat cracks. To avoid this, special heat treatments are conducted on the sections of the rotor which balance them out and reduce the occurrence of heat cracks during operation. This has led to a longer lifespan for the rotor and a sustained period of utilization without anxiousness.

Blue Rotor Hat Finish

• To add a decorative touch and to help prevent rusting, the bell cap has been painted blue.

About Bedding

• To ensure the best possible performance of a pad designed for high temperatures, it is necessary to carry out a procedure called ‘bedding‘. This demands preheating the pads prior to any extensive use, which enables them to reach the ideal performance level.
• Competitors in top tier motor racing circuits, including SUPER GT, WRC and several European tournaments, necessitate the paramount level of bed set–up.
• It is necessary to break in semi–metallic brake pads correctly to guarantee superior temperature efficiency and prolong the life of the pads and the rotors.
• How to Bed:
  • When utilizing a vehicle with a newly installed product, ensure that the rotor temperature remains between 400–500°C. Avoid pressing down harshly on the brakes. Add atari, and when the rotor temperature drops to 100°C or lower, the operation is complete.
