None that I know of. Closest ratios are 3.42 and 3.73.

Had 3.73. Too much tq, along with a short tire spell BOOM. 3.55 would keep me from shifting into 5th on the long straight and not give up much power out of the corners. I'm afraid I'll be going back to the 3.42 gear. Slightly stronger and I'm now overpowering the 12.6 wide tires due to 525 tq at the wheels, a short 25.5 height tire and the 3.73, not to mention getting into the rev limiter on a regular basis and needing to shift too often.

I'm using the nt01 which I am very happy with but it is much shorter then tires of similar size.

what about going 3.73 and going with a little taller tire or do the 3.42 and add some more hp.

Why not get a rearend that can hold 500+rwtq? Stock 10 bolts aren't exactly made to do that, road racing or not.

Thx for the heads up on the 3.55. I'm going to verify they indeed have them and if so, that will be the gear ratio I go with.
