AP1 vs. AP2 Gear ratio

[DMC_S2000]

They say that AP2's first four gear is closer than AP1...but when I tested it on a gear calculator...the AP2 is slightly longer... try at John Maher Racing: Gear Ratio Calculator or at http://www.f-body.org/gears/... Im sure of the tire size that I've input for AP2 but is AP1 really got 225/50 R16 rear tires when I input it in the gear calc the results are insane...I mean the results were LONG gears...I just based the AP1 in Gran Turismo 4...I'm pretty sure that the gear ratio in their is accurate at real life...right?...but also when I watched a video at youtube.com named "F20c vs. F22c"...I saw Keichi Tsuchiya and another pro racer testing both...I really saw that the gears of the AP2 is shorter! but at the gear calc I saw that AP2 is slightly longer!
(speed in redline)
Gears-------- AP1(GT4)-------AP2(gear calc)--------- AP2 (based on the video)
1st-------- --71 kmh--------- 72 kmh----------------- about 60 kmh
2nd ----------110 kmh--------112 kmh-----------------about 94 kmh
3rd-----------151 kmh-------- 155 kmh---------------- about 123 kmh
4th---------- 191 kmh --------195 kmh---------------- about 160 kmh

If somebody really knows the truth please tell me...tnx...

I instructed a guy in an AP2 at at Laguna Seca a few months ago and he was redlining 3rd gear at about 75 miles per hour. My AP1 redlines 3rd gear at about 92 miles per hour. I've hit 120 miles per hour in 4th gear when it touched the rev limiter. I'm not sure about the other gears.
