LSD not locking when turning right..
I'd imagine it's been covered, but I couldn't find it when i searched, so I'll just ask here.
Not all the time, but sometimes, when sliding to the right, the diff doesn't lock right. It gets very very annoying. I've heard this is a common problem, not just with rx7s, but with all manufacturer lsd's as well. Since I don't really feel like paying $800 for a kazz LSD right now, does anyone know a fix to this problem? I cahnged the fluid, but didn't put any treatment of any kind in the diff. Thought i'd ask before i did. Thanks.

Use a gear oil without LSD additives. That might give the diff some more grip.
What gear oil did you use?

Opinions are like........
I assumed that the owner is talking about the s4 which I presume is a clutch-type LSD and not the viscous ones used on newer models.
Sorry but you have no idea how LSD additives work. It doesn't sense anything. LSD additive is a friction modifier that causes slippage to prevent LSD clutch chatter. The goal of the LSD additive is to smooth engagement/disengagement without reducing actual holding capacity or torque capacity of the LSD. That is difficult to do. Excessive doses of LSD additive will reduce its effectiveness and is a common mistake.
If a clutch or cone type LSD is worn out, it should be rebuilt. But, if you use a gear oil without LSD additive, like Motul Gear 300 or Redline 75w90NS, you might be able to improve its holding capacity a little. You'll have to live with a little chatter. But, I doubt that an ancient LSD would even chatter.
Concerning the viscous LSDs, there are some shops that can actual refill them with different viscosity silicone oils for improved capacity.
