Are their any advantages to having a ZC tranny aside from an Si tranny? Whats the top speed on the tranny?

 

the only two advantages for a zc tranny in stock form are:

optional lsd from the factory
uses equal length axles

now if you put the Si final drive in the zc tranny, then its definatly a lot better over the Si...

 

Sounds like a plan, thanks. I definatley like the equal length axles too. Wouldn't be better with an HF final drive?
