Gearing

Don't want to be stuck between gears or on the rev-limiter a bunch so choosing the best gearing / power / weight is critical.

For the 6 Speed equipped RSX-S:

The 2002-04 final drive is 4.39, 65 mph second gear with the 25" tall 225/45-17 tire @8300 rpm (400 over stock).
2005-2006 FD is 4.76, 61 mph in second @8300 rpm (200 over stock).

The Base 5 speed RSX  also uses the 4.39 FD (with taller transmission gearing), 160hp at a lower more useable rpm than the S, and similar torque to the S also at a lower rpm. Buy in for the Base should be less too.  All USDM cars are equipped with moonroof / sunroof.

My poor math says a 23" tall tire on the Base will reach 61mph @ 7200 rpm; stock redline is 6800.
