Thinking about gears...

[Fiorano]

Right now I have 345/30-19s in the rear making my rear tire diameter approx. 4.8% larger than stock and effectively reducing my gear ratio to 2.93.

I am not running much more HP than stock (Corsa and [******] airbox), so which should I go with 3.55 or 3.73

3.55 reduces to 3.39
3.73 reduces to 3.56

How bout 3.45's?

 

[Fiorano]

With the larger rear tires, I think 3.45s would be too low.

3.55

3.55 would be perfect for you. I have 3.55's on a stock tire setup and it is a shade to high. Somewhere between the stock 3.07 and 3.55 would be perfect which is where you'll bewith your set up.
