Thank you. You have rated this product.

The BEST RX8 Limited Slip! This is the unit in our race cars. We are proud to be an authorized OS Giken dealer. OS Giken has been producing performance parts for both OEM manufacturers as well as the aftermarket since 1975. Professional racers, home grown racers, and performance enthusiasts alike have come to know and respect OS Giken, and we are honored to be able to bring these products to you.

So what makes the OS Giken differential so special? It is in the details! There are lots of differential options on the market, but here is what makes the OS Giken stand head and shoulders above the rest.

1. Lock Timing Technology "under normal driving conditions, the OS Giken LSD acts just like any normal differential. Once full power is applied, it turns into a true 100% locking unit. However, unlike other clutch type differentials, what separates the OS Giken from others is how smoothly this transition is performed. In addition, due to unique gear driven center section, the OS Giken differential is extremely responsive, allowing it to transition from lock to unlock instantly.

2. When we say 100% lock, we mean 100% lock! Many lesser differentials on the market claim 100% lockup ability, but due to their low number of disks and small diameter, they never are truly able to sustain such high lock percentages...ESPECIALLY IF YOU HAVE A BOOSTED MOTOR! Not so with the OS Giken. These differentials feature more disks than any other differential on the market, which are placed in a forged housing. This not only keeps heat to a minimum, but spreads the load over a greater number of disks, which is the reason it works so seamlessly.

3. Less undesteer = more goodness! When your Miata enters a corner off throttle, the spring inside the patended pressure control ring reacts immediately and the differential immediately unlocks. This is done so quickly and efficiently, that the car is able to turn in quicker than with convential differentials. However, when power is put down upon corner exit, the OS Giken unit immediately returns to 100% lockup, allowing for less chance for wheel spin.

4. No More Figure 8s!!! Ever wonder why some aftermarket differentials require you to dizzy yourself with endless figure 8s as a break-in. The reason is simple: "because the components used are not machined as precisely as in other units. The OS Giken unit is built to such stringent tolerances, there is zero break in required. Simply install and go. The uniquely tuned "lock timing" allows the diff to runn looser until torque is applied. This feature give the diff a super smooth takeup when exiting corners. Datalogs show it accelerating harder than a factory Torsen or modified OEM clutch type. Fully rebuildable at authrorized service centers all over the world Fully tuneable, can even be set up as a full 1 way or 2 way.

I just installed the Borla exhaust on the MX5. Sweeeeeeet! Thanks, Andy

Thanks for making this work and providing great customer service! I had a full weekend with the install, but man was it worth it. The flywheel was such a good choice. I can't believe how much easier rev-matching down shifts are. The ACT is surprisingly easy to live with, even with the engagement point very low. I'll tackle that when it stops raining. Thanks again for making this happen this weekend.
