you need to be a little more specific. are we talking about overlays, other small gauges to monitor things like afr, boost/vacum, oil press, fuel press. or are you talking about a complete new set of guages like what autometer now sells?
i use an autometer procomp ultralite II air/fuel guage on a single pod on the A pillar. i love it and it meets al lthe contingency ratings for all major racing organizations. id have more but i use my tuner (sniper) to monitor things when i need to. the A/F guage gives me a good heads up while im driving around. pretty much it just all come down to prefference on looks and what you do with your car. lord knows there are plenty or different gauges out there to fit your needs.
well installing the pillar was extemely easy for me. Not to sure about the dash pod one though and my car came with the white faced gauge cluster on it because it's a cobra.
actually they're not to bad at night time. Fairly easy on the eyes. Yeah, and the only reason i bought the NV series is because i did an LED light swap in the cluster to make the cluster numbers a brighter green to match the autometers. But definitely the quality of the Autometers are excellent.
The bezel pods arent really any harder than the pillars,I like the bezel pods for my water and oil cuz they right there when I look down at the other gauges.But I am also gonna add the pillar for a couple other gauges.Sorry no pics yet.
