I cant find a place to mount the rear LI units on my 997. I've seen some pictures of them mounted within 8" of each other right above the license plate but that doesnt seem very effective. I've also seen them mounted vertically on the sides of the rear license plate but I'm not sure that is safe.
Any suggestions?
Edited.
Optimum placement in green locations on the rear of a 997 or 996. US spec bumper suck for anything else.

Only place I have seen them mount is on the side on the license plate frame. A guy used some plastic cutting board material to build up the surface. This allowed him to get the heads even with the bumperetts.
I spoke with Cliff at LI and he said a vertical mount would require the high powered LI's which are just too expensive. I'm going to go with the 9500ci instead since it has a workable mount for the rear.
NOOOOOOOOO!Quote:

I would hate for you to make that mistake. The rear head on a 9500ci is worthless. It is more or less just a detection sensor. One standard power LI head has more jamming performance than all 3 ZR4/9500ci heads combined.Quote:

At 65 mphs, you will have covered ~90 ft in one second. Well, if you pass a Leo who is setup on an onramp or overpass, he would have to be able to initially aim at the outermost portion of your tail lamps and lock your speed within a second of you passing him at 65 mph. Does that not sound absurd? At 80 mph, you are covering ~117 per sec. The window of opportunity closes up very quickly.
It's far easier to lock a speed at close distances while initialy aiming at the perimeter of most vehicles. The footprint of the lidar gun's beam is extremely tiny at that point.
In your first post, you say that "the heads mounted 8" apart doesn't seem too effective." Well as long as they are level and aligned, they are very effective. You will lose some close range detection performance but that remaining performance will never be less than that of an optimally mounted 9500ci system or Blinder m27.
TIFWIW. Your money would be better spent on a LI quad and V1 combo.
On this particular vehicle, using an Ultralyte LRB and aiming anywhere within the green box resulted in JFG under 100 ft. After that, the LI was able to detect and jam everywhere on the vehicle.

OK. OK. You make a good point and I've further researched the 9500ci and I'm not liking what I'm reading. So back to the LI's... two LI's will not fit above the rear license plate without covering the license tag lights. One will fit fine (in between the two lights). Should I just get one high power LI and put it there?
FWIW... I'm going with the STI-R Plus RD.
To save money you could go with a LI dual up front and a LI HP dual in the rear.Quote:

It is mounted using existing holes, it levels and aligns both heads, and it incorporates new LED lighting which is wired into the factory license plate lamps which are partially covered. And it does all of this with an unobtrusive footprint. The lighting on that plate is much more vivid than it was before. Did I also mention how well the setup performed in my post above?Quote:

:confused:
In this picture would green work?
Yellow would be my second best (looking) location but Cliff says not to do that.
Red is fine.
Purple aint gonna happen.
Green is very low and I suspect the heat will cause damage to your system. Yellow is not advised. LOL about the purple. You sound just like the owner of the C4s picture I posted above. Red is your only option. You must have misunderstood what I said in post #12. The bracket used was created for that particular application. It was not provided by Laser Interceptor. It was a 911 specific piece created for that owner. It mounted to existing screw holes behind the plate and also to the screw holes for the license lights. And because it partially blocked those lights, it has LED lighting incorporated into it.
I thought red would be the only feasible location.
Do you have any other pictures of the custom mounting plate on the 997?
Unfortunately, no. It was a one-off piece created for that application.Quote:
