I am going to Livernois Motorsports tommorow with a LARGE check and I want to order all my parts so once my bodywork is done I just have to install them.

The guy at livernois suggested a Eaton Posi with 31 spline axles. He said it would be about $1k installed.

My question is what axles to go with, and is the Eaton unit good enough for ~ 350rwhp? I also road race, so anyone use the Eaton at an open track event?
 
for the price of an eaton i would go for the torsen since you will see some track time. 31 spline torsens can be had for around $440. or you could get an 03 cobra diff for half the price--i run one and like it.
