I'm eventually going to install these as well, and have done a bit of research. It is not advisable to install all three up front:

First many users of the ZR3 that I met with in the past also mounted their rear laser jammer to the front figuring if two heads work well, three heads would be even better. In mentioning this to the engineers they related that the two front laser jammers are designed to operate at a different pulse rate than the one rear head and that because of this the front jamming effectiveness could actually decrease if all three heads were placed in the front. Not one to miss a challenge, we actually took some time to test this at our new testing facility and yes, in some situations we did notice a decrease if jamming when all three heads were all placed in the front.

OK, I am glad you guys are discussing so many options but I thought laser jamming is a federal crime and is punishable in all states now. Has something changed in the last week?

Or is everyone just playing chicken with the leos?

EDIT: nevermind, I was thinking Radar Jammers.

At the same time, you should also realize that the ZR4 is typically considered to be a "less powerful" jammer - look at any and all independent testing, and you'll see that its performance, although what I would consider to be "ticket saving" in the real-world, absolutely pales in comparison with just about any of the laser-diode based jammers, and is even much less capable than its main competitor, the other LED-based jammer that's just as well-known, the Blinder.

In-truth, since the rear head of the ZR4 offers so little true, real-world protection, I would instead advise you to bring it forward, to supplement your jammer setups' frontal aspect. Place it over your front plate area, center-mass - allowing critical reinforcement there - and also, at the same time, this should allow you to further displace your "front" jammer heads more outboard (while still respecting the critical "18-inch rule" per all hardpoints and total coverage area), for better overall protection.
Thanks for the feedback everybody but this guy 'blai4754', why did you respond? It's guys like you that have cooled me off to this forum. I asked for certain feedback and I guess you haven't heard yourself talk enough today and needed to share a little with folks that can't just walk away when you open your mouth. I've already purchased the piece, I think that's pretty obvious by the way I phrased the post, maybe not entirely, but still. Why rip my choice with such enthusiasm? I just asked where to place the shifters and you take off tearing down my purchase choice. You go to lengths to post a link to a review written 4 years before the ZR4 was even produced, I think that shows where I'm coming from and where your coming from. I'm sorry if I'm wrong I really am.

Radar jamming yes because it's controlled by the fcc laser no fcc doesn't regulate light frequency.

Actually I never tore down your purchase. I was responding to Morricus' comment about not placing the rear with the two front shifters. I got intrigued when he made that comment and was curious if it was true.

Furthermore, what I gave you in my previous post was quote (word for word) from the forums... not my words.
LGT+WRX very informed opinion at 03-05-2009, 12:58 PM if you had taken the time to read through that page never mind the entire thing. By the way, 2009 was less than 3 years ago. And the ZR4 is still popular product at a reasonable price.

I have the ZR4 laser shifters if you haven't noticed with my 9500ci so I'm not sure why I would tear down my own purchase? I offered you advice on where I placed my ZR4 shifters and if you look through all my posts or even participated more on this forum, you would recognize I never ever tear down anybody's purchases.
I read through all 6 pages before responding while at work doing all of this on my cellphone.
If I get ripped apart for providing my opinions through research on my own time I won't give you anymore then...

Unbelievable.....

I really don't see where blai4754 was attacking your purchase. I can see how you could be turned off by this forum on occasion, as sometimes members seem to pile on anyone who makes the slightest mis-informed comment, but I do not believe this is one of those times. Just one car guy trying to help another, or at least offering a valid opinion regarding your original question.

OK. I just asked one thing and got a whole lot of other negative stuff really unrelated to the specific question. I've asked for opinions before and respect anything anyone has to say, but this was a simple tech. question. Anyway, let's move on, thanks.

The key to mounting the shifter receivers is they need to have an unobstructed view and mounted level. That is why when they are mounted in the rear they are mounted on the license plate. Cops are trained to aim the laser at the tag in the rear and the same for the front if the tag is center mounted. The cops are looking for the area that will provide the best reflection back to them.

For me the hardest part is the unobstructed, which means the receiver must not have anything in front of it, including grille mesh. On an Evo X I think that could be the 2 intake ducts in the center bumper cover.

Got everything mounted yesterday and it turned out great. I trimmed slits in the grill mesh for the heads, I need to post pics cause it turned out super. Also, I called beltronics about mounting all three heads up front since I know of some who do that. Beltronics said not recommended since they are phased differently and that it would reduce effectiveness. I was wondering is this essentially the $2000 set up some places charge for the installed system, is that system just a 9500ix with the zr4 shifters? I got my gx65 and zr4 shifters one on craigs list the other on ebay for $670 combined new in the box. As was mentioned earlier by another member, the Blinder shifters do perform better according to testers, but I'm pretty happy with this bang for the buck system.

Pics?

Did you move the third (rear) shifter to the actual rear of the car? if so, where'd you mount it?

thx ahead.

Good info. Thanks if you are still on this forum.
