did yall notice a diference?
just to give an example as to what hes talking about im running a 27" tall tire and going with 4.30 gears. it will be similar to running 4.10s with a 26" tall tire
I have 3.73's with a M6, and at 70 mph I am tacking 15-1600 rpms. I also get 20mpg around town and 28-30 on the highway. I thought with 4.10's that 1st gear is almost useless making the car a 5 speed. Can anyone elaborate.

see i like to know this too. I have 3.42s now and 6th gear feels like it studders until i am like at 70+ mphs. So i figured 4.10s would work great in my truck with the six spd. But knowing how short first gear is now, how is it with 4.10s? I mean if the 6th gear is such a dramatic change, that would mean that first gear must take a hit also.

Verdad Gallardo this would mean you have a 2.73 gear for 70 mph at 1600 rpm's.
If you have a 94 up T56 your sixth gear ratio would be .50
and a 3.42 gear will give you 70 mph at 1600 rpm's.
I have a sixth gear ratio of .50 and a 4.10 gear,At 70 mph I am at about 1900 rpm's.

Thats a question I have wondered about too. I went from 3.42 to 3.73, Huge seat of the pants difference.
I ran a set of Richmonds and had them Mikronited. The pinion ended up loosing up somehow and I chipped one tooth on the pinion. When I went back to the track with 3.42 instead of 4.10 I only lost 1 mph in trap speed.
I'm kinda glad I killed my 4.10 geared rear. While it was fun it was also quite interesting. I remember when I put my new motor in and got on it the first time, damn thing tried going sideways on a quick 2-3 shift.
Granted I'm usually broke when I buy tires so its rolling on Riken Raptors, but still it was crazy.
I didn't notice a change in gas mileage. Still could drive over four hours on the interstate before stopping for gas, I probably just shifted earlier in town with them.
