Default 3100lbs,LS2,cam, 150shot..what gears?

Ok my 350z(ls2) weighed in at 3100lbs even the other day(within 20lbs) I have the MN12 t56, a 238/240 cam,headers and ill be spraying a 150shot at the track. I have 28" tires. I currently have 3.50 gears and have the option of going with 3.90s or 4.08s...do you think im good where im at or should I step up to the 3.90s..or higher? Car is mostly a street car but will see the track at least twice a month over the summer.

How high do you want the rpm to be through the traps? I would at least stay with the gears you have in there for now to see how the car runs. Bob

3.90 ratio most likely depending on your trap speed. I assume you would be in the 124-128 range?
