I'm about to start a build on a 2011 NC with the 6 speed manual and the Mazda LSD. We are pretty much doing a build across the whole car...engine, suspension, cooling, adding a turbo, etc.

I wonder what you guys think about the best single LSD for both street (mostly) and track use without regard to cost or maintenance...simply the best?

 

Os giken and Cusco. Os giken has more clutch plates than Cusco from what I know so in theory will hold a little more power.

 

I noticed the two mentioned use clutch plates rather than gears...is there any inherent reason plates are better?

 

You can tune them.

You might be able to find a quaife. They are gear based. Tomei is also gear based but don't have great reviews.

I bet you will find most people are running Cusco or os giken.

 

What are thoughts on a 1 or 1.5 or 2 way? I don't think I understand the real differences or which would be best for me.

 

Actually, looked into this myself and will be going the 1.5 route.

 

If you're looking for the OS Giken, We have them in stock with our custom tune. On sale, plus store credit. https://949racing.com/product/os-gik...ermiata-tuned/

 

I bought your NC XIDAS and something else I think...though I can't remember what right now. LOL

 

Well, complete the trifecta with the OS Giken! 😁
