Like Bill B, I am using VDO Vision gauges, but have chrome bezels. I was very impressed with the electronic speedo - it takes a feed from a range of sensor types (mine is just the standard Porsche G50) & you can have any set of gears / wheels / tyres - to calibrate it, all you do is enter calibration mode by starting the engine with the button pushed in, push the button at the start of a measured km or mile, push the button again at the end & its done. Mine was only 1 kmph out at 100kmph when checked against my engineer's fully calibrated setup.
All in all, good quality German engineering at a reasonable price.
Kind Regards,
Peter D.
