New member considering a Z

Qwimby1

I'm not sure about his logic. I'm really only familiar with Torsens which are common in the Miatas I've been driving. I read here that the 370 lsds aren't very good. If that's the case, should I worry about getting a sport model or convert another car? What's the preferred diff in a 370Z and how much does the conversion cost? I'm not equipped to do that job myself.
