I tried to keep that in mind when I put my gauges together. My car is a dd and is never tracked. I'm def. going to do gauges on the dash in my s13 because the car will be abused quite a bit more and like you said earlier they need to be clearly visible. The one I worry about most on my ka-t car is oil pressure. My boost controller doubles as a boost gauge and records spikes and max boost and it is clearly visible on top of the steering column in giant digital blue numbers. So technically the A pillar boost gauge is only used for vacuum; I have thought about deleting it... The wideband is kind of in a shitty spot but I was def. not drilling holes in my perfect dash, sticking a holder on it or running a triple pod for that matter. I run an Enthalpy tune anyways so I don't even really have to look at it. It's more for peace of mind. K.I.S. (Keep it simple!)
