ok I looked at alot of posts on here and some say this, some say that, I dont like to do reposts of things out there but I am just going to ask this for I can get the answers im looking for. I am thinking about getting new gears for my 2009 4.0 v6 Premium Coupe auto mustang. I already have CAI, duels, and tuner for it and people say this is the next best mod to do (this is my daily driver year round). I know there are the 3.73 and 4.10 gears so which ones should I get. next is the lsd, I know what it does but is it important and should I buy it? and last should i just upgrade to a 8.8 rear end instead of having my 7.5? I am looking for more get up and go from my mustang so is this going to be worth it for me and am I going to be happy with the results? also how much money am I looking at including labor and what is the cheapest yet effective way to go? Thanks! (also one more thing i forgot to mention is I have traction control on it so is this going to mess with it at all?) :help:
