ive seen one person that removed the air bag from the passenger dashboard and put the gauges there, it looked pretty good but im the type of person that i like to hide my stuff and keep it as secretive as possible because it attracts attention and people talk alot of crap, i go to uti and this guy had a b16 swapped eg and he had a dash mounted tach, and there was a group of kids gathered around it cause he had his hood removed and they were talking about how he was "boosted" because he had a gauge on his dash, i wanted to smack the hell out of them cause anybody that knows about racing would have known it was a tach and you can look at his bay and see he doesnt have a turbo aha but besides the point, i refuse to use pillar gauges, cause it does attract unwanted attention and its a bit ricey
