Should I upgrade to the optional posi?
http://web.camaross.com/forums/show...threadid=191331 This is the rear-end I want to buy.
The question I have to ask: is it nessessary to upgrade to the optional posi unit on a car with my power level? I plan on adding N20 at a latter date and don't want to do this twice.
Thanks in Advance
Andy
