For racing, rally or street, Endless only uses the highest quality materials and design to achieve the best performance possible. These calipers will cope in the toughest of conditions without flexing or losing accuracy. Combine the calipers with RF650 Racing Super Fluid for optimum performance. Your pads will be applied and released with great precision and reliability.

Blue Anodized Finish

When raw aluminum reacts with the oxygen in the air, a hard surface film develops on aluminum which prevents further degradation. The process is called oxidation, and you can think of it like rust. The anodizing process leverages this natural phenomenon, and takes it a step further to produce an extremely hard protective layer of aluminum oxide. The result is a finish that is far more appropriate for racetrack use. Anodizing creates a uniform surface that is much more abrasion resistant than paint or powder coat.

Curving Slit Brake Rotors

Drawing out the essential performance possessed by the brake pad and demonstrating optimum brake performance is an important role of the brake rotor. Curving Slit is a high-quality brake rotor which more than fulfills this role through Endless’ unique heat treatment and the application of the Endless Blue heat-resistant coating. Also, by making it low cost, it can be used by a wide variety of users, from replacements for rotors which have worn down to Street – Circuit driving.

Cost Effective, and More On So Many Levels

  • Endless Steel rotors are more cost effective, and offer a wider range of performance options. Many drivers and racing teams prefer the feel and characteristics of Endless steel rotors.

Special Heat Treatment Process

  • With prolonged hard driving, the rotor surface will expand and contract due to heat, causing fine cracks (heat cracks), and you will not be able to obtain appropriate friction. To prevent this, special heat treatment was performed in advance to stabilize the components of the rotor itself and significantly reduce heat cracks during hard driving. As a result, the life of the rotor has been extended, and it has become possible to use it for a long time with peace of mind.

Blue Rotor Hat Finish

  • The bell hat part is painted blue to aid in preventing corrosion resistance and also can be expected to have a dress-up effect.

About Bedding

Circuit-dedicated pads that emphasize high-temperature characteristics, in order to bring out the original performance, it is indispensable to perform the work called “bedding” in which heat is applied in advance before hard driving to make a hit.

Bedding is always done in the top categories SUPER GT, WRC and various races in Europe.

Before using semi-metal brake pads, proper bedding is required to stabilize high temperature performance and extend the life of the pads and rotors.

How to Bed

  • When driving on a circuit when a new product is installed, raise the rotor temperature to about 400 – 500° C while avoiding hard braking, and add atari. After that, if the temperature is lowered to 100° C or less by natural cooling, the process is completed.

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions.
