Default OS Giken Review

Where do I start off?

Well I guess I can start off by saying, "HOLY F*CKING WOW!!!" I am utterly astonished as to how different the car responds to inputs versus when I had the OEM Type R differential in. It took everything that I had learned over the last 10 years and threw it all out the window! It took me the whole 2 days to get used to driving the car, because no longer could I depend on lift-throttle oversteer or left foot braking to get the car to rotate. The only way the car turns now is by flooring it!

So with that said, I am now going to be toying around with suspension setups that are much looser. I noticed I am able to get on the power a lot earlier, but the car still has a tendency to push even on throttle quite a bit. We began dialing it out with suspension damping adjustments, but just about when I thought I had it setup ideally. The driver side front Toyo RR had a belt shift causing catastrophic understeer on right handers. I had no clue about the date codes needing to face certain directions in order to keep the tire from destroying itself.

All in all it was a great learning experience this past weekend, definitely going to have fun figuring out the fast setup for the car!

Very interesting feedback! Is this a 1-way LSD?

That's exactly the way my car handled, even though mine is still more of a street car than anything. It still pushes, however I could get on the throttle sooner and harder than before. I wonder if tweaking the plates or ramps could further improve cornering. I must say though, the OS Giken LSD right out of the box is bad ***.

No. there's no point in tweaking these on a FWD platform. (Not that you really could anyway). The 1-way and 1.5 ways are actually rather nice, honestly.

I use a 1-way for my street honda and a 1.5-way for my circuit TA honda. (Both are Cusco LSDs)

How is the Cusco 1-way on the street? The OS G is really easy to drive on the street even without power steering.

Thanks, makes sense that it pushes a bit.

Only because of the fact that it operates partially on deceleration as well as acceleration. I only noticed a tiny bit of push, but it was in a turn situation in which the car would naturally understeer rather heavily.

Yes, but it takes a lot of time. There are so many adjustments you can make to the OS Giken LSD's.
