Changing gear ratio

[Koncrete]

what all is needed to change? I had 2.73's when I bought the car but had 3.42's installed...

Do I just go to the table and replace 2.73 with 3.42? and that's it?

Simple huh? Toss in your tires and wheels, tag the new differentiaL RATIO click on the recalculate button and save. Upload and you're done.
