hondacars.com--part of Honda's website--and Road & Track list the EM1 final drive as 4.4:1.

i looked some more and found this on his site

The 4.266 final drive is a debatable spec. If you look in a Helms manual for the 99+ Si Coupe, you will see that 4.266 is the final drive spec. Eddy Lin has found that to be false - he physically took a 99+ Si tranny apart and counted the final drive teeth which calculated to a 4.40 final drive ratio. So, yeah..it's debatable, but I believe it to be a 4.40, even though the Helms manual could be (and probably is) wrong
