ENDLESS RACING MONO4 FRONT PERFORMANCE BRAKE SYSTEM FOR VA SUBARU IMPREZA WRX STI

4POT caliper version of forged and molded Monobloc Calipers. Conducting many tests in pursuit of reduced weight, durability, radiation, etc., Endless reviewed the shape of the details time and again before achieving perfection. They also enabled installation of wheels from 15 inches as well as increasing installable wheels.

Specifications

  • Weight : 2100g
  • Size : 141mm x 72.5mm x 270mm
  • Compatible Rotor Diameter : φ300mm – φ355mm
  • Std Color of Kit : Racing Anodize
  • Std Compound for Kit : Type R / MX72 / MX72-Plus
  • Compatible Wheel Size : 15″

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.

FORGED MONOBLOC CALIPER BODY

Monobloc Calipers forged and molded through several thousand tons of pressure. 4 years after its conception and 1 year after the completed prototype it was entered into test races repeatedly and changed its specifications while also obtaining a body that is sufficiently light and hard to compete in races. The processing of the highly difficult piston cylinder was cleared using advanced special technology. The finished body was completed using an ultra-hard anodized aluminum. It is the final product of the technology created by Endless and its “never-ending challenge” as it continues to focus on quality forging.

“E-SLIT” DOUBLE SHAVING EFFECT

The long slit which draws gentle curves and the E slit which runs above the long slit are what make E-Slit Rotor impressive. The pad is constantly kept in optimal shape through the double shading effect demonstrated by the long slit, which gently carves the pad, and the E Slit, which gives strong brake force, providing further improvement of brake force. When the long slit on the rotor surface side disappears and the letter E floats up it is about time for replacement.

Also, even during the period of use, the brake rotor may be damaged due to aging deterioration such as rust and corrosion, so it is recommended to replace it at least once every two years.

Specifications

  • Material : Steel with Special Carbon
  • 1-Piece Design
  • Slit Shape : E-Slit
  • Special Heat Treatment

E-Slit

  • The E-Slit rotor consists of the narrow curved slit incorporated with 4 smaller E-Slits. The smoother shaving of the pad by the long curved slit and the increased friction provided by the E-Slits maintain optimal brake pad condition at all times. The rotor material consists of a special carbon blend, an Endless original technology, facilitating stable mu-levels, decreasing heat cracks and extracting 100% of the brake pads performance. Slits are designed for optimal shaving.

Cost Effective, and More On So Many Levels

  • Endless Steel discs 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 discs.

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.

ULTRA-HARD ALUMITE CALIPER BODY

Ultra-hard alumite is used for the caliper body of our monoblock series. A tough ram coat is used for the rotor bell housing. This makes it possible to significantly delay the discoloration of alumite even when used under high temperature conditions when driving on a circuit.

HARD ANODIZED FINISH

The finish is a hard anodizing, which is the preference under track conditions. 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.

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.

I’ve never loved a bar of soap so much.
Scent: Unscented
For starters, I suffer with severe sensitive skin, Eczema (which also has a huge gut health component) - however I’ve been struggling pretty bad the last few months. In my search to find more natural and nontoxic options, I stumbled upon castile soap - I’ve been using it to wash my dishes, clothes, skin. Finding out that the alkalinity of the soap can destroy sensitive skin barriers (even with diluting). I think it is been the leading cause of my skin dryness. (Despite lathering up with things like organic Shea butter and castor oil). I was getting very frustrated and very stressed and I found this family owned company. I’ve always wanted to try more tallow products, and know how amazing honey and castor oil is for health and rejuvenation (inside and out). I figured what the heck this is a pretty decent price. When I say I do not want to stop using the bar so I mean it like it is now becoming a struggle for me to get out of the shower because I want to keep blathering up because it feels so good. As a bartender and someone who hates having dirty hands - I really hate washing my hands, despite how much I feel obligated to do it. I’m contemplating bringing a bar of soap With me wherever I go so that I have good soap to use 😆. I’m about to buy some from my mom and try other products. I will update if my skin issues have subsided (in a month or so I reckon). I am getting an Eczema patch on my stomach/torso area, my inner thigh to my knee, and back of legs as well. As well as for the last month despite how much dry skin I take off my face, And how much castor oil I rub in - even with a moist appearing face - the flaky skin pokes through. I immediately felt soft skin upon using this product on my face. Normally, I would test out a small area, but with only a few ingredients I was like screw it. I ran out of soap and it’s either that or using watered down castile. Please give this a try. I cannot attest for the scented versions. Also, I saw someone say that it burned their eyes? Castile burns my eyes - this, does not. (And I probably scrub my eyes harder than I should post makeup remover - which is a balm - and just on the eyes).

Great first impression!
Scent: Unscented
This soap was delivered last night, so I used it first thing this morning. So far, I am very satisfied. It has almost no odor—which I like. It created a good lather and left my face and body feeling soft and clean, but not dry. The natural ingredients mean it’s actually good for my skin! It seems to be a great value. The only improvement I can suggest is to make the edges a little softer (more rounded) because it’s quite square to be rubbing my underarms (and other delicate areas). If new details are warranted, I’ll edit this review
