Well im not sure what u have, i forget what my numbers where when i had the stock gear, but i kow u dont have 10's

if u was in my situation right now what would u get. 4:10's or 4:30's? if i ever race we usually do it on the highway from a roll sometimes we'll do it from a stoplight but they usually wont cuz of cops. when we do it on the highway i usually shut her down at 110 when i raced the mach 1 i shut her down at 120 and was still a steady car length behind it and he kept that one car length the whole time

To be totally honest with u, i havnt taken mine above 90 since installed my gears, and that was about 5 months ago, so im not sure at what mph i top out..........but if i were u i would just go with, 4.10s u wont regret it......u will pull soo much harder in every gear
