Default LSD / Final Drive for racecar advise please

...Looking For Some Helpful Advise...

I have a '99 SiR (EM1) track car (B20/B16 Frankenstein) that I use to compete in Time Attack events. Recently during a test day, my S80 Type-R differential failed inside my stock EM1/B16 transmission.

I'm now looking to upgrade to an aftermarket LSD, and a 4.7 final drive. I'm leaning towards either a Gear-X OR a MFactory MFactory Competition Products - Performance Driveline Components final drive.

But I'm not sure which aftermarket LSD I should be buying. OSGiken is a contender.

Reliability is top priority, followed by Cost, as these parts are not cheap. The car sees no street driving, and is a dedicated track car with just over 200whp. Any advise, and where to source these parts is appreciated.

Thanks in advance!

You never stated what fail in the itr transmission, what your end goal is, but if you're looking to beef up synchrotech might have you need for synchros. As for FD's....well one makes it inhouse while another uses multiple locations...
