This i what i finally decided on for gears:

Get 4:10's if your NA

Get 3:73's if your superchargered...turbo'd...or on the bottle

 

What information are you using to make those rules up? I think n20 cars LOVE 4.10's.

 

I would say that 4.30's are great if you are staying N/A. With a built motor and some suspension work (and tires) they would be great on a nitrous car as well, in my opinion.

 

Here's an odd question. After installing my Fidanza aluminum flywheel I've noticed that my car isn't so torquey anymore on the bottom end. On the flipside, my top end pulls much harder and faster than before. Question is knowing this does that mean my car would pull better all around with adding gears like 4.10's or 4.30's?

I see people saying those gears give you great low and midrange power, so if my car is super good up top now, it will basically even it out then right?
