Well fixing to get one of the last pieces to get this thing back up and running. I thought I was all set and was going to go with a 3400 billet 911 buuuuut after doing some reading on here I am having second thoughts on needing a billet cover on it. I am trying to free up some weight and rotating weight is worse so with my mods looking for high 10's do I need it? Any thoughts here would be appreciated.
