<----Envious

well what are you trying to do, go fast in a straight line or go fast around the track?

the JDM R has a much shorter final drive, so the gears would be much closer, making it a quicker car with a lower top speed

us R has a taller FD so it would have a higher topspeed but get there quicker.

if you wanted the quickest paossible, get the 4.785 FD from the JDM R and put it in the US R.

to tell you the truth i just WANT to go fast but mostly in a straight line and on the streets.
