I had the Evo series gauges in my Subie when I had it. I believe I still have photos somewhere in my journal... I feel they are not very easy to read. The actual reading display is considerably smaller than the over all gauge. And the viewing angle is critical.
Other than that they are very responsive and accurate.
I've had some success making a sort of wedge that angles the gauges in my ATI pod toward me. I'll need to look more into it, but I really want to find a car with these and take it for a quick spin to see how they are when driving. Thank's for chiming in, I'll check out the journal!
