Interesting fact...a bolt-on 2V, full weight car, manual, will top out higher with 4.10s than with 3.27s since with 4.10s you can run 5th out farther than 4th gear with 3.27s. Kudos to Cliffy Ks website. 5th gear with 3.27s can't be topped out due to HP-weight-aerodynamics etc...5th gear can be rode out with 4.10s due to being in the meat of the powerband.
Another reason why 4.10s are the shiz.
Huh, that is a really good point. Did not know that.
