you should only notice about 300 RPM's higher with 56's than 30's depending on your mods.

with stock trans and tires, you will be at redline in 4th gear before you hit the 1000' mark on 4.56's

RE: 4.30 or 4.56 Gears ?

What kind of rpms is your motor turning? Is it an aod or a t5? With 4.56's your going to have to be pulling some really high rpms, probably 6500-7000 or your going to be topping out before the 1/4. Where are you trapping now with the 4.30's? It better to keep your car in your power band then it is to over spin it.
