it depends on goal for the car. Everyone saying they like acceleration. well at 600hp then, now 700, I can tell you with teh 3.31 on the 2013 manual, acceleration is no problem. 3.73 will be a very good mix gear. 4.10's if you dont like first and plan on moderate power. But if you plan on going crazy. 500+hp you wouldnt want anymore that 3.55's if you plan on going to the 1/4 mile alot. If you wanna do alot of street/roll races, then the lower gears work great. It all depends on you.
