My Broadfield special:
Race Technology
Wideband 02 (Left)
Fuel Level (Right)
If you ask me, why have 4 gauges you have to simultaneous glance at (which isnt going to happen while road racing) or a single cluster with programmable warning lights? You see a flash, you have 1 place to look. Also has integrated shift lights, turn signals and aux ports for boost gauge and other such features. Oh did I mention data logging? If you can afford it, go with a single cluster (race tech, racepaq, aim mxl).
