Gauges are you a fan or not?
Not usually one for plastering gauges all over the car but I wanted to monitor exhaust gas temperatures as high EGTs can tell many stories of multiple problems I wanted it in a gauge rather than just ecu data so I could watch it in real time without the laptop being connected. We sell an adapter ring to fit a 60mm gauge perfectly in the drivers(RHD) vent : https://www.fensport.co.uk/products/airvent-gauge-pod-60mm-gt86-brz I then chose the Blitz SD 60mm Gauge as it will record peak temperatures to be recalled at the press of a button and the lighting perfectly matches the instrument cluster back lighting.
