I am looking at racepack for my race car. I am thinking that for an extra 1000 bucks or so I get the ultimate dash, rather than buy a hodge podge of racing gauges. basically I am completely rewiring my car because it is going to be a full fledged race car. I have been in need of some more accurate measurements of things like temp and oil pressure and oil temp.... so I am wondering what peoples thought are.

1. ease of use?
2. ease of installation?
3. worth the money?
