I thought I'd share some thoughts regarding the ZR4 shifters installed on a friend's Nissan R35 GTR.
I recently tested the shifters against my Ultralyte LR B 125 pps gun and was a bit taken back by the admirable performance. I had advised my friend against purchasing these shifters (I told him to purchase LI's), but he wanted integration with his 9500i. C'est La Vie, as the saying goes.
a) Besides the published results of the shifters themselves in GOL's July 2008 testing and various other anecdotal results, I thought the shifters were not going to provide any meaningful protection.
b) The shifters were mounted in a very hidden location, quite recessed within the front grill of the vehicle (at least 2.5-3 inches). This was due to my friend wanting the shifters to be totally hidden from prying eyes. The shifters were mounted horizontally, with approximately 7 inches distance separating them. My friend's 9500i was hard wired high, next to his RVM.
c) After viewing Mem-Tek's latest CAD mockups of the shifters themselves, the LED emitters would be partially blocked by the grill work of the GTR.
d) The testing was done at night which probably assisted the output of the shifters and coincidentally the lidar gun itself.
e) The GTR was a metallic gun metal gray in color and had a front licence plate. A Laser Shield was used on the front plate. *Further testing of the Laser Shield will be done at a later time.
f) The GTR was equipped with HID lighting and as it was at night, they were activated.
g) Temperature was around 50F (10C). Brrrrr...
h) I am a qualified Lidar and Radar operator.
- Front center mass/plate shots were JTG from 850-1000 ft out (The outer limit of our testing).
- Driver side headlight shots were JTG till it reached around 85-100 ft.
- Passenger side headlight shots were PT from at 700-800 ft out.
- My friend's 9500i failed to alert to any of the lidar shots, save those that were purposely aimed at the top/upper portion of the windshield.
PS. The GTR is an extremely impressive car.
