I was driving by a car the other day, and I saw that his gauges were mounted via suction cups to his windshield. I looked clean.

This has interested me. It would save me the trouble of installing the piller mount I have.

Does anyone know who makes them? Where I can get them?

I hope this answers your question.

 

... you gotta do a pretty good job with the wiring for it to look clean

 

That sounds ghetto. I mean, seriously, suction cups?
