Factory ZC LSD
 

I have an opportunity to buy a ZC tranny with factory LSD for 250 + shipping. I was planning on putting a Quaife in the si tranny that's in the car now. The Quaife would be $695-895 depending on which Si tranny I decide to use (35mm bearings or 40 mm bearings) The ZC motor is getting built and boosted this winter. What would you guys do? How do you think the factory LSD compares with a Quaife? Is the fatory LSD more like a Phantom grip style or Kaaz, Quaife style?

I dont think many of us have ever seen a D-series LSD diff, they are very rare, and only found in the ZC trans. If they are like B-series lsd's I am sure it will be just fine.

I would kill for a LSD. You have the oportunity to make the best transmission if you combine the best features of both transmissions. You need to combine the Si final drive (ring gear) and fifth gear with the ZC gear set. You end up with a transmission that has the lowest final drive and the closest gear ratio. Go for it!!!!
