im gonna get some rims maybe 18' or an offset 19' in the rear and 18 in the front. will 3.73 gears be good?? somebody told me the bigger the rims the higher the gears. idk

 

Size of the wheels has nothing to do with a need or want for changing your gearing. Your overall tire diameter does.

 

^^^ correct, so long as the tire is in the area of 26 inches tall then your close to stock. as far as 18 or 19 in rims,,,, not something i like the looks of, places the car off the ground to far. 17 is the biggest i would go with but thats me looking through my eyes. its all about what you like. there are many pictures on the net you can look through to get a better idea of what you like. 373 gears are nice and is what i will be going with in my 12 bolt when i get the cash to get it.
