I find the 3.45 to fit the car perfectly. As long as I'm in the right gear, feel like I have a fighting chance against some of the big boys on track (I always lose though
) great for city driving as in gear acceleration increases and you never use the full rev range in town (at least I don't
) and on the highway ( have over 35k on my 2011) not too busy at all as I'm around 3500 at 80... Good luck, but I love this mod
