I have a SkyPro XGPS160 GPS Receiver arriving today from Amazon. This is a skid resistant brick that can be put on any karts bottom plate and receive multiple GPS signals to provide lap timing within 1/10 of a second. It connects to my iPhone via Bluetooth and using Harry's LapTimer application we should be able to use qualifying times to set the race orders next year. I may try to find a used iPad that we can use in place of my phone to see the lap timings and details.
My early Christmas Present.
