I have n 07 with 355's Was going to go with 410's or 373's but with the blower it would be pointless for the change. if you are staying NA the I would recommend going with 410's.
I have 3.73s and like them. My car came stock with 3.31s. If you get the gears, you should also get a handheld tuner like SCT or Diablo to adjust the speedo for them or your speedometer will be off a bit.
you also have to understand the higher the gears the quicker you'll be off the line but you will lose your top speed. If your only interested in your 0-60 time then you will be very happy with a higher gear ratio. If you do a lot of highway driving and enjoy driving 100+ then you may want to stick with stock or 3.55
3.73's arent worth the money.
But 4.10's are! If your going to drop a few hundred in the rear, make sure you will notice a difference. You will love 4.10's, and notice a difference. Then get a cam next. Because gears and cam are an awsome combo!
