Brake calipers and rotors from ENDLESS

Generous people at ENDLESS have sent us an additional special gift for OS-86! present


It's a brand new Monoblock caliper / E-Slit roter set. new

They have been a great help for building OS-86, and the list of their generous donations is keep getting longer...

We might as well name it OS-ENDLESS-86. bleah


Without further ado, let's install this bad boy. wrench



A decently sized OE brake kit came with stock FT-86...


But there is no comperison to the presence of ENDLESS kit.  They are in a different league in terms of its appearance and performance. good



It looks like no driving condition will break this caliper... danger


The installation went smoothly without any complication and rather quickly as well.

Both front and rear brakes has been replaced / upgraded:





Cannot wait to test this beastly brakes at a track. cardash motorsports


---Product info from ENDLESS website ---

E-Slit rotor:

"Endless racing rotors are available to suit the most abusive of racing conditions in the motorsports world. The rotors are made from specially heat treated carbon steel, and are lightweight also. They use the “E-Slit” vane technology to offer the most well balanced performance based on the choice of brake pad. They also run very cool compared to our competitors.

The E-Slit rotor is comprised 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 is   comprised 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.

The bell housing material is a rigid, lightweight, high-strength   aluminum alloy metal capable of withstanding high temperatures. It also   decreases unsprung weight, which contributes to stable braking."

Monoblock caliper:

"Four years in the making and after extensive testing  in race conditions, Endless has finally produced this caliper to achieve  their extremely high rigidity and lightness standards. The difficult  and complex manufacturing of the piston cylinders has been achieved  through highly advanced engineering. The body is made with only the  strongest aluminum material. This is the highest performance achievable  using the highest production technology and highest quality of  materials."

1st stage of mods complete

We have just finished the first stage of upgrading our OS86 test car. (Don't get confused with OS-88 sequential transmission...)

OS86 is currently armed with OS SuperLock LSD, OS Grand Touring performance clutch, ZEAL suspension kit / brake pads from ENDLESS, and a body kit from MODELLISTA. motorsports

These upgrades already made a significant difference in its performance, but still something to be desired... wrench

MORE POWER and better grip!  ...but, that could wait for awhile. happy01

Now is time to do more cosmetic upgrades(?):


OS86 is a test car and not a promotional car, so we wanted to keep its look as simple as possible.

We do have a variety of OS Giken stickers including some eye-catchy ones, but decided to stick with something subtle.


Hmmm, it feels like we are forgetting something. (later found that there was no sticker for the clutch)sweat02


This has nothing to do with OS86, but Izmon yet again found a clutch assy. just sitting on Clutch-wizard's work table:


It's a twin plate Street Master (AKA Grand Touring), and didn't look anything out of the ordinary.

But when you take a closer look: eye


It's Street Master Carbon sign03

One of our dealers is testing the clutch for us, and once the test is complete, we will be moving on to its production.

Crossing our fingers for a good test result. good


Come to think of it, we should try using the carbon disk on OS-86 clutch...

Let's go bother Clutch-wizard about it. catface

86 Clutch complete

There was this clutch assy. just sitting on the table where Clutch-wizard (CW) works his magic. danger

As you can see, there was no printing on its cover...


All of our products built for order should have OS Giken logo printed, which means this one must be a new clutch in development sign01


As usual, Izmon trapped CW and began his interrogation... think

Izmon: "What is this clutch for?"

CW: "For our FT86 / FR-S"

Izmon: "Weren't you just measuring the OE clutch a couple of days agosign02"

CW: "I already had some measurements to work with so just needed to confirm the info I received with our vehicle."

Izmon: "So is the development finished now?"

CW: "Almost, I need to adjust  the release sleeve and we will be ready to test it with our 86.  The test should give me enough data to decide the flywheel weight for an optimum inertial effect.  For now I have made two flywheels for the test: Light and Ultra-light"

Here are some pics comparing the OS and OE clutch:




After adjusting the release sleeve, it is time to install. smile

CW informed us that the clutch kit is currently called Grand Touring RE single-plate. flair

He didn't give us any more info besides its name for now... crying

Here's the installation scene:


Apply proper torque to tightening the flywheel bolts.

Then install the disk and cover.  It is best to use a clutch centering tool to have the disk centered correctly.


Izmon is pretending to help so he could have his picture taken... sweat02


All of us are interested in this new clutch so many of us have taken it for a spin. car dash


Clutch pedal felt a bit heavier with OS Clutch installed, but that is because the OE clutch pedal had such a light pedal feel to begin with.  Besides that, everything else was what you could expect from OS clutch products. good

Thanks to the reduced inertia, the engine response and engine brake were certainly improved.


There was just one person not entirely satisfied with its result... Clutch-wizard. shock

He felt a slight vibration out side of the engine's peak power range, and wishes to make an improvement.
We just hope he remembers that the clutch is using a light-weight flywheel...

Anyhow, the clutch should be available in no time. (as long as he doesn't find anything else to improve)

Reserve yours now happy01
