The OS factory survived unscathed in the recent catastrophic events in Japan.

WolfGTI received one of the first production GT series clutch kits for the R53MINI.






No flimsy stamped steel body and plastic sleeve here.

 

The obvious differences between OS Giken and the brands you mentioned nazrin are price point, materials, and construction, except for CM’s FX600 twin-disc, which has comparable ease of use, similar construction, and an equal price to match. As mentioned earlier, OS Giken STR clutches are user friendly on the street while maintaining plate pressures and friction materials needed for high power output MINIs. A CM FX400 4 puck disk or ACT G6 race disc offer increased clutch performance, but compromise easy clutch engagement characteristics.

No, not overkill, your MINI is no longer at a stock power output level, increased torque places increased demands on the clutch. It would be a shame to lose some of its potential through a slipping clutch. An OEM clutch is adequate in the majority of circumstances and can be nursed to function well at the thresholds of abuse, but when you want or need it to perform extraordinarily, it runs the risk of failing to deliver.

In response to that question as it pertains to an LSD, it makes a great deal of difference in a front wheel drive vehicle. I have a Quaife ATB differential and I’m very pleased, I feel the power being delivered to the road during drives out of corners, and I get a kick out of two wheel burn-outs. However, it seldom rains here so I get to realize the benefits often; an ATB differential is limited when one wheel loses traction completely, in the wet it’s less effective (the spinning wheel continues to spin robbing power from the opposing wheel, an open differential is even worse). Given your location I would assume the environment is wetter than mine, this is where an LSD like the OS Giken pays extra dividends, traction is available precisely as needed. Also, the OS Giken Super Lock LSD doesn’t contribute to understeer like an ATB differential does. You can live without an LSD, but once you have it, you’ll wonder why you’ve denied yourself the pleasure.

OS Giken GT Clutch Preview

OS Giken has two versions of a new clutch kit for R53 and R56 MINIs soon to hit the streets, Models GT1CD and GTS1CD. The same heavy duty clutch cover as previous versions, but now the pressure plate is attached to the cover to reduce noise and smooth out engagement. The clutch disk is the same durable metallic material as before, ensuring longer life than OEM, and greater resistance to overheating.

The GT will have a dual-diaphragm spring for increased clamping pressure and is recommended for applications up to 400hp. The GT pedal will be a little stiffer than the GTS and current STR, more like a typical race clutch.

The GTS will have a single-diaphragm spring and is recommended for applications up to 300hp. Pedal feel is more like the STR, which means it is just about perfect. Reports from the prototype owner have words like "love" in it, and he states it is easy to drive in traffic.

MSRP is $1790.00 for each model.

 

I installed a GTS clutch kit in an R56 recently. It is undoubtedly a race clutch, but maintains good street manors. Backing up a steep grade is fairly easy to do without bogging. The noise level is somewhat muted compared to the STR, it lacks the metallic ringing tone, although as most single mass flywheels do, it shares the characteristic wooden rattle at idle. Unlike typical race clutches, pedal effort is light, much like stock.





OS Giken R56 flywheels now have a timing notch for locking the flywheel when changing camshafts or removing the head.




OS Giken was quick to implement the design change after feedback from MA member btwdriver (Brian Wisler). OS also increased flywheel thickness to match OEM; stock flywheel bolts are now a direct fit.

 

OS Giken has launched a new website, OS GIKEN.
