The purists aren't going to be happy but all going to plan, I'm hoping to run the Haltech IQ3 Street display.
I've chopped into a spare facia to get an idea of how I'd make a flat area for the panel, plus create space for other gauges such as eboost2, start button, etc.
After doing the mock-up in cardboard plus putting some photos to scale on it, I'm happy with how it would look.
I'll now get an aluminium infill made with the intention to glass it in then blend in and refinish as close to factory (in black) as possible. I'll back mask and do some chrome highlights around the border etc. The original warnings (park brake and so on) I'll probably leave dead as the IQ Street has them incorporated.
