O.S. Giken "DualCore" LSD

I actually am pulling my 1.5 OSG LSD to send back to them for a rebuild and setup change. Ever since going to stiffer springs and sticky tires like RE71RS, the inside wheel spins so badly in corners and curbs, it's not even worth driving anymore at the track. Not sure if it's all my car setup/power, or a combination of high wear when I first installed it and didn't have a diff cooler for a couple track days, and only had a Z1 diff cover (which are absolute garbage BTW, they actually increase oil temps because they don't adequately lubricate things inside like an OEM one does with the rounded interior). Trust me, everybody should ditch those and just use the Nismo cover, which I did switch to, in addition to a cooler.

Regardless, the LSD needs adjustment.

The idea of a Wavetrac sounds great, but the lack of lock on coast/decel still bothers me. Who knows, maybe they still work great on track. Not having to run a diff cooler certainly would be nice, and make diff oil changes a helluva lot easier.
