when i had just some basic bolt on with my car years ago i had 3.73 and i like them alot. i didn't think they were to much. 3.73 are a good gear if you have a t-5. i you have a good tire out back and a good suspension you should not have to much of a problem. i dont think you are going to see that big of a difference between the to gears, when it comes to traction.
