That's a real bummer. I've fought with going 3.73 or 4.10's for my car and I was leaning towards 3.73's before and this confirms it.

That RPM seems super high. I was only around 2500 RPM at 120kmh on my stock T45 w/ 4.10s IIRC.
What size tires are you running and how was the speedometer calibrated?
The rpm will be accurate at if actually doing 60 mph.rpm guage will always be accurate.
If your speedometer is off how would you verify you are actually going 120kmh? RPM would be accurate regardless of indicated speed yes.
Based on this calculator you should only be turning 25xx rpm

At 60mph (gps measured) the rpm was at 2500.
Sorry, I neglected to mention that I was using a gps to determine actual speed/rpm.
