EvasiveMotorsports Testing Out New OS Giken For FR-S BRZ
 

New OS Giken Products For FR-S BRZ

We at Evasive Motorsports is testing out and doing R&D on the newly developed OS Giken GT2 Grand Touring Clutch and LSD. The Grand Touring Clutch is the latest development to our clutch lineup and retains all the technology from our Racing Multi-plate Clutches, but with the addition of our unique “floating pressure system” to provide a smooth and chatter-free driving experience. The Grand Touring Clutches are available in single. Twin plate configurations are still under R&D. OS Giken has design these clutches and can be matched with a soft or hard clutch cover to suit the engine output. With a OEM pedal feel and the ability to hold up to 400hp [/B][B]making it suitable for both street and track cars.

EvasiveMotorsports is also working with OS Giken to work on the LSD prototype and testing out preload settings. For the final revision for consumers. We will be testing at Sonoma Race Way and Laguna Seca Race Way.

Technical Aspects OF OS Giken Clutches

-By combining a decreased disk diameter (vs OEM) with a solid design and carefully selected components, our clutch allows for extremely efficient power transfer and improved engine response.
-Our specially designed clutch cover contains a unique leverage mechanism for the diaphragm spring, resulting in a higher clamping load of the clutch disk(s) while reducing pedal effort.
-Integrated ventilation holes reduce heat generated inside the clutch system and allow for friction plate dust to exit outside the clutch system, thus increasing reliability and safety.
-Both the clutch components and the flywheel are constructed using the same specialized steel alloy to ensure similar heating characteristics across the assembly to minimize warpage and increase durability.

The OS Super Lock LSD is the culmination of over four years of extensive research and development that led to a revolutionary LSD design with the capacity to house an unprecedented number of friction plates (up to 28 plates in total). Combined with our patented lock timing system, the Super Lock LSD is able to achieve complete lock in a progressive, smooth, and quiet manner, making it suitable for both street and racing performance.

this thing looks amazing. i think it's awesome evasive is being so involved in the FRS/BRZ community.

:happy0180:

Sweet, they're the best

What's the HP or ft/lb rating for the LSD?

My FR-S wants this inside her.

Oh my that's beautiful.

We will be testing it out this weekend at Sonoma Raceway!

What's the super singles torque capacity?

Also to the guys thinking about buying one of these kits, the "rebuild" cost is extremely cheap... For down the road disc changes. I can't stress how streetable these clutches are! Even their high end kits designed for high torque/power are unbelievable in my opinion... I drove daily with a OS Giken triple disc in a 600+ hp car, pedal feel was comparable with my vehicles OEM clutch/flywheel setup.

Also, the noise always lets people know you're serious or think your cars broken lol

On my wish list.

Let us know bob! :happy0180:

Still looking for an answer.

its around the same as the clutch

-Randy

Would this LSD be suitable for Drifting do you think?

Are you guys aware of an LSD solution for 550+ crank hp?

Best is going with a like a different car diff that can handle up to 550+ crank hp. Im sure the OS Giken can handle 400 area but how long is the question.

Holy mother........ I guess the LSD ain't cheap right ?

Should be around the same price as the s2000 area!

Laguna Seca today testing the new OS Giken clutch and LSD on the BRZ.
