9/11 Never Forget
Good info! I went from 3.73 to 3.31 and I want to go even lower to help with traction. How do the 3.15’s effect your 1/4 mile runs if you run it at the track?It really does depend on the other cars gearing and power band as well. My 60 roll with 3.73's was adequate for most cars but up against a A6 mustang of the similar power I was severely out gunned. I changed the ratio so that now I start 60 rolls in 2nd gear around 5500ish RPM and it's a monster
You can swap the carrier for a 3.15 and the ring and pinion into your current housing or do a full swap. I had a 3.15 loaded housing laying around from my 2015 so I just swapped the whole thing.
