i just bought a GT500 and would like know what gear is better? 3.73 or 3.90 or 4.10

its mostly a daily driver and it might see some racing action but rarly.  

I would go with 3.73's from what you have said. Going from the 3.31 to that will be a nice trade off. I had 4.10's in my GT500 with a 28 inch tall drag radial. Mainly was going to use a fun toy and drag race duty.
