Speaking from experience (see sig. 4.10's baby!), I can support the claim that first gear is
very short. The first time I got on it after the gears were in, I swear the thing revved to redline before I knew what happened. I already had the drag radials on so I don't know what traction would be like with regular street tires but I'd imagine it's a challenge. As far as highway driving, my rpm's are at 2500 going 70mph.
If you get 4.10's, be prepared to shift alot!! I hardly even use first gear on the street. If I had to do it over...I would have done the same thing
4.10's are a blast once you get used to all the shifting.
