Endless 6POT / S4R Front & Rear Performance Brake System with 1PC Rotor for GR Subaru Impreza WRX STi

Endless 6POT / S4R Front & Rear Performance Brake System with 1PC Rotor for GR Subaru Impreza WRX STi

The Endless 6POT/S4R Front & Rear Performance Brake System for Subaru Impreza WRX STi Hatchback is an ultimate upgrade for those who demand race–inspired braking performance. This system includes four–piston calipers and two–piece rotors for superior stopping power and improved fade resistance. The calipers are constructed from lightweight aluminum for reduced unsprung weight and improved brake cooling. The rotors feature a cross–drilled, slotted, and vented design to increase heat dissipation, reduce brake fade, and provide superior performance in wet conditions. This braking system is designed to provide superior stopping power and improved handling, making it the perfect upgrade for serious track and street performance enthusiasts. The 6POT caliper ensures robust braking power even in cars that are highly modified with a powerful engine, and is the optimal choice for street performance sports cars fitted with a powerful engine.

For their racing, rally, and street applications, Endless ensures maximum performance from their calipers by only using the highest grade materials and designs. Their products have undergone stringent tests to guarantee that they can endure even the toughest of situations without compromising precision or dependability. To get the most out of your calipers, pair them with RF650 Racing Super Fluid for superior control when braking, with your pads engaging and disengaging with accuracy and trustworthiness.

Blue Anodized Finish

• When aluminum is exposed to oxygen in the atmosphere, it begins to create a protective film on its outer layer. This is called oxidation, which is similar to corrosion. Anodizing takes this natural occurrence and strengthens it, forming a strong layer of aluminum oxide on its surface. This gives it a smoother and more durable finish, making it an appropriate choice for applications that require sliding tracks. Anodizing offers a more consistent finish that is more resistant to scratches than paint or powder coat.

“E-Slit” Double Shaving Effect

• The E–Slit Rotor is extraordinary, largely due to its lengthy slit, that delicately forms smooth curves, as well as the E slit located above it. The double–shading effect produced by the combination of the long slit and E slit maintain the pad in top–notch quality. If only the letter E is visible and the long slit on the rotor has disappeared, it is a sign that the rotor needs to be swapped out.
• It is recommended to change the brake rotor at least every two years, even if it appears to be functioning adequately, since rust and corrosion, as well as other signs of wear and tear, can cause it to weaken over time.

E-Slit Rotors

• Created with the user‘s needs in mind, the E–Slit rotor boasts a lengthy curved slit plus an additional four smaller E–Slits in order to give an incredibly soft shave. The long slit paired with the extra friction of the E–Slits stops the brake pad from losing its shape. Manufactured using Endless‘ exclusive carbon–blend, this rotor allows for the highest mu–levels, reducing the chance of heat cracks and ensuring the brake pads hold their best performance. Every detail of the E–Slit rotor has been carefully thought–out to guarantee the best shaving experience; its design is truly remarkable.

Cost Effective, and More On So Many Levels

• Endless steel discs are widely used among racers and drivers due to their cost–effectiveness and range of performance benefits. Furthermore, the sensation and features that come along with these discs make them even more attractive.

Special Heat Treatment Process

• The regular and prolonged use of the rotor can cause a buildup of heat, potentially causing small cracks (heat cracks) due to the surface of the rotor expanding and contracting. To combat this, a pre–treatment process to reinforce the rotor parts was conducted to lessen the chances of heat cracks when the rotor is used at higher speeds. This has increased the rotor‘s estimated lifespan, giving customers with more peace of mind when utilizing it for a prolonged period of time.

Blue Rotor Hat Finish

• A fresh coat of blue paint has been applied to the bell to not only fend off corrosion, but to give it an aesthetically pleasing look.

S4R

• Endless has created a cost–effective 4–piston caliper that does not sacrifice braking power, even when it is situated at the rear of the vehicle. Competitors like Racing 4 are more expensive and are meant for users who have front brake calipers, but those on a budget can now rely on the more affordable Endless caliper kit. The caliper is built with a forged body, designed to be space–saving yet maintain the dependability for which Endless is renowned.

About Bedding

• It is essential to ‘bed‘ circuit–dedicated pads that are specially made to be heat–tolerant in order to get the most out of them. This refers to heating up the pads before subjecting them to prolonged, intense usage.
• Competing at the highest level of motorsport, including SUPER GT, WRC, and other races across Europe, is a testament to the caliber of a professional racer.
• It is essential to perform the appropriate “bedding–in“ procedure prior to utilizing semi–metallic brake pads in order to guarantee maximum high temperature performance and elongate the service life of the pads and rotors.
• How to Bed:
  • Before introducing a new part into a circuit, make sure to warm the rotor to a temperature between 400–500° C, avoiding any sudden slowing down. Afterward, the atari can be put in and let the rotor cool to a temperature of 100° C or lower, completing the process.
