I have long used an Escort laser/radar detector. I believe this should be one of the first things one should purchase if they are driving a high profile car such as a WRX/STI. You are noticed and you will be targeted. I get targeted a lot. Thankfully, I have slowed down to the posted limit by the time I am in range. I don't speed excessively as a rule, but why open yourself up to a needless ticket? Drive responsibly, but use an electronic co-pilot.
