I am running 4:10's. Pretty much useless power on the street. Havent been able to put the stickies on because its not ready for that quite yet. I am gonna swap to 3:73's pretty soon..

im thinking about running a 3.70, maybe a 3.55 just to stay in the boost longer..

I'm m6 also for now. It's the last thing on the drivetrain I need upgraded.

I'm running a 3.89, but I have a TH400.

I did however have a T56, and thats why I put the 3.89 is in there. I will most likely be switching to a lower gear soon.

3.23 still...

Trust how does your car run with the 3.23's? I would think it would help traction quite a bit on the street. I have a fabbed 9inch with 3.25's thats going in my car.

The 3.70s in my car are perfect. M6 here.. D1SC... 600rwhp. I had 3.89s... didnt like em.

i pmed you.....looks like im gonna go with my orignal plan and do the 3.70's!

3.50's.. it doesn't give me as good track times as 4.10's would but I still manage an 11.64 on street trim and the car is quite fun out on the street.

I'm going with a 3.42 on a 408 F1a, M6. Figured it will make it more useable/fun out on the street.

3.73 on that ***.

im planning to swap out my 4.10s for a 3.73 gear once the blower goes on.

'Trust'

Honestly, not sure yet. I've only ran it once at the track, total of 2 passes, and my injectors are WAY maxed out. Before I knew, traction was still pretty worthless on the street, and the car ran 11.06 at 103 on the brakes pretty hard at the track, but not hard enough I guess. Full weight, A/C, 1/2 tank, no weight reduction.

My new injectors etc. are in and with any luck I will make a track appearance on the 20th.
