Haha must suck at times, but don't get too sad... you have a KB 
I went with 3.73 even though I'm basically stock just cuz I didn't want to shift so often. I think most ppl on here would agree with 3.73 for a twin screw. But if you are on the track a lot, getting 28" tires would "extend" the gear, like teej said.

Don't listen to these guys. Drop the gear unless you're gonna run a 28" tall tire. Dropping some gear will help with traction as well as give you more pull in 4th at the top of the quarter. People should know by now that 4.10's and blowers, especially twin screws, don't mix.
I mean sticky tires and lower control arms are definitely a good thing to add, but there's more to your setup that just tires and lca's won't realize.

That's the dumbest thing I have heard all day.

You go right ahead say what you want. Anyone thats been on here this long should know the rule of thumb is that you should run 4.10's or higher with n/a cars, 3.90 or lower for centri cars, and 3.73's or lower for twin screw cars. You dont need 4.10's in a twin screw car at all. You get the instant torque at any rpm so its not like it has a power band or anything that you have to get up into. whether youre at 2000rpm or 5500rpm, you'll be making the same amount of torque pretty much so its kinda pointless to have all that gear and have you top out your car at 110 at the top of 4th when you could be topping out at 140 and getting traction to get there in a timely manor. I'd bet you would even say that 3.55's for a turbo car would be wrong too...
But seeing as I know nothing at all and you are all-knowing, i guess none of that is valid info.
