HIT REDLINE Laser Interceptor is by far the best.
Down Under In Australia I have it on my WRX and X5.
The WRX has a V1, Laser Intercepter, Radio Scanner and Veil. I travel over 1500Ks a week and YES I do speed. If I didnt I would be dead by now, from going off to sleep.
When you speed you stay awake and alert. (I havent had a car accident in over 25 years).
I have mounted my LIs on the X5 in the same place as you but used a wireless cheeta setup.
FYI Ive had what the call in the game a Jam To Gun with the X5 on a Laser UltraLite 2020. So it seems a good place to mount them.
