Had the 4.08 final drive installed, took a before and after video of where my RPMS were at, and are now at after final drive install... I will post that soon...

At 80 MPH I am at 3400 RPM'S before the gears I would be at 3000 RPM'S.. Gas Mileage in the little bit I have driven seems to have went down .4 around town , have not done any highway driving..

I can live with all these things just fine, maybe not for everybody but to me this was one of the better mods I have done.

As far as increased in performance it is substantial ... The car accelerates like a beast, My tires spin 2x more than they did but it is still controllable, but If i fully throttle it in first at 4k they will break lose right away, I can no longer just mash the pedal down and go... Its cooler here now so thats hurting traction too but traction is def more of an issue than it was, but like I said its still controllable.

I think this was prob the most dramatic mod I have done since I first installed test pipes and the intake in the begining... It's without a doubt faster than it was and not just by a small amount.

I can not wait to get back to the strip with some good tires... the fact it puts my car in the power band in 4th going through the 1/4 instead of just getting into 4th and the actual increase in acceleration I have now I have no doubts that this will shave .2-.3 tenths off my 1/4 mile time.

Now the question is , what is next ? Flywheel ? Try M370 out ? Go Long Tubes over my test pipes ?

I am not sure, But I am sure that I am extremely happy with the outcome of this final drive.
