Yeah....interested on this as well.

From what I am hearing 4.10s are just fine for 35s on a 2012 auto and 4.56 for 37s.

My buddy ordered 4.88 for his 2012 with 35s. Anxious to see how that works out for him.

If you had it to do over again what ratio would you go with?

That's so weird I have 4:88 with auto and 37s and I'm at about 2800 rpm's at 70. Did you calibrate speedometer? That's all I can think of unless I'm missing something.
