I'm building a 240Z into an ITS car and have a few questions before I go any further.

Do I use the stock seat mounts or should I order mounts for whatever seat I go with? (Also any recommendations on a seat?) I'm going to be using it for HPDE's for the first few times on the track so I'm going to have to put a passengers seat in also...should I just put in a stock seat with a 5 point?

Do I run a locked or limited slip rear end? I've heard running a locked (welded) rear end can break stub axles, which are impossible to find except on a parts car. I have a lead on a LSD, and while putting it in looks easy, putting it in right looks expensive.


I wish I would have just gone ahead and bought one finished looking back, but damn, I can tear a Z apart with my eyes closed now.
