OS Giken LSD - Any difference between US and JDM LSD?
 

Hi,

Anyone know if there is any difference between the US model OS Giken Super Lock – Part: MZ072-HA, and the Japanese D-MA202061404-S?

Track only, medium/low HP.

Cheers.

I think the Australian version rotates in the reverse direction.

Yes, I think you are correct...unless you have the special straight cut camshaft timing gear set to correct it. :giggle:

Factory Torsen vs Os Giken? About .5s per lap on any track. Over 1s on some tracks. There is a reason every purpose built road race car that is allowed to run a high end clutch type, runs something like an OS Giken.

No, Japan OS Giken (part D-MA202061404-S) VS USA OS Giken (part MZ072-HA).

I am unsure if the Japanese OS Giken LSD just has a different code, or is actually a different LSD???

OS Giken is in the process of tweaking the design a tad with some new design concepts and I know and 949 has a special setup with a slightly different tune than what OS was originally selling.

You could call OS Giken here in the US to find out. I don't know myself. The tune we sell is it's own part number, different than the MZ072 every other US dealer gets. We're currently doing some testing for the gen 2 tune.

Just pinged the guys there, "Minor Preload and lock timing difference". One assumes it could be tuned to replicate the Spec-S or any other tune.

Cheers Emilio.

Ps. How far away is your updated 'tune'?

No ETA but I wouldn't fuss over it. Only a small evolution from our current SPM tune, which is in stock BTW.
