The VDO gauges look nice, but I want an oil pressure and temperature gauge in bar and °C, not in PSI and Fahrenheit. The same goes for the Autometer gauges.

For the third gauge I'm not really sure yet. I already have an AFR and boost gauge, so was thinking about an EGT gauge. But maybe that's a bit overkill as I never take it on a track and a voltmeter would be better?
