I agree. Tach on Right puts it out of the line of sight in the upper rev range. I love the 5 Gauge setup on my 1976 Porsche. Big Tach in the Center, Speedo to the Right of Center, and Critical Temp and Oil Temp/Pressure Gauges to the left, with clock and fuel farthest out. ALL Performance Cars should be this way, but Tach on left makes most sense.If not centered then I think I prefer it on the left as the important portion of the dial is closer to the center of my sight line. Have not owned a car before with it on the right but feel like redline would be too far right and not in direct line of sight.
100%. It was reference to the classic Porsche layout I meant as well.I agree. Tach on Right puts it out of the line of sight in the upper rev range. I love the 5 Gauge setup on my 1976 Porsche.

That said, is a moot point for S550's with the Digital Cluster. Between the shift light and ability to run the Tach in a flat graphic across the top of the Cluster, the Tach takes Center Stage. You can also set the cluster to give a large digital number rev counter in the center of the Tach.
Given a choice between left and right though, I would go left for the Tach.
