Is the RPO SPO label not on the "back-side" of the console door? If it is NOT post up the last 8 digits of your vin and I'll take care of it!

last 8 should be: R5XXXXXX

Factory build: 3.07 G44

Your car should be a white/gray coupe with a blue transparent top!

Your MPH seems pretty close

2100 RPM with a 3.07 should be close to these #'s

1st: 17+

2nd: 32

3rd: 52+

4th: 74+

THANKS MUCH!!!

I did those speeds using a 275 tire calculation rather than the 285 that was/is on your car's "original build"! Using a 285 tire spec the 4th gear is likley 75+ just a bit!! I went back and looked at the build!
