gear swap?

i currently have 4:30's in my car. i was thinking about going to 3:73's or 3:90's(if they make em). i can't get my damn car to hook up at all plus my shifting is entirely too quick. unless i'm just a pu$$y. let me know what you guys think.

Thanks!

If its geared correctly for the trap speeds you anticipate (which is the primary consideration), then you need to put more tire under it.

how much of a tire?
