IIRC, it is hard coded into the ECU to deploy the spoiler at 75mph.

So, my best guess to work around this is either modifying the speedometer input to trick the ECU that 100mph was 75mph (without screwing up the speedo displays in the cluster) or modify the ECU code itself.

Maybe someone else knows more and will jump in...
