Can an S5 Speedo be calibrated?
Like the title says.. For some reason my speedo is ~4mph fast.. I know it doesn't matter, but it's bugged me since I bought the car. And If the needle is anywhere under 80, it bounces just a hair (assuming gravity plays a part in that). It's the little crap that gets to me.. Don't get me started on dash rattles!!

Do you have OEM sized wheels and tires?

Yes, mechanical speedos can be calibrated.
It's done by putting a small gearbox between the cable and the gauge, the gear ratio in the box brings the speedo into the correct reading.
I had it done to my 240Z several years ago.
