Pleased to report that I finally got my vehicle back after a major engine job was completed. I can now put some serious miles on the new STiR+ and the two other remotes (that have been repositioned to clear line of sight positions, even though the car had to be butchered to do this). We'll finally see the impact of such a re-arrangement...and I hope it turns out to be worth it the damage incurred to the 5 to accomplish this.
Still, the remotes are quite low and they're definitely not going inside the vehicle. I'll use a Redline for extreme high mounting, given the positive results I have had doing this.
I'll get video as I can. My route is to include PA, OH, WV, KY, and possibly to TN, NC and SC. Should be more than enough to allow me to follow up with my planned deep-dive review of the STiR+.
