ZR3 Install on an M3. Mounting problems? Vertical?

**kalel** · 06-11-2006, 02:33 AM

Here's a follow-up to an old thread, as this one is necessary for my ZR3 install on my M3 (exact same Silver Grey as original poster[replacer_img]. All 3 heads up front

i agree, thats a very good idea. if he has an m40 and has one on the back you could also put two under the fog lights and two in the middle for even more protection

heres what i'd do with the three heads. i'm no expert tho. ask sethy about this

StealthJamal, that set-up is ideal but the fog light ducts are way too small for the heads to fit. It looks like they will, but nada. Also, the upper part of the bumper where he currently has his heads is angled at about 15 degrees so that the heads are angled up and not level. His install is 100% not level.

I am bummed on what to do about my install. It is not even close to stealth. I mounted in the exact same positions as the original post, but had to use the brackets so I could have the heads level. the use of brackets makes it look like sh*t IMO. And no, you can't get flush with the bumper.

Can I mount the heads vertical? 2 in both sides of my chrome grill??

I do agree that does look horrible. At this point is there anyway you could get a refund? I have a feeling you have been mislead by forum members into thinking the ZR3 is a good unit. There was testing done this weekend that proved the units did awful. I hate to be the one to break it to you but some forum members here live in a fantasy world. If you look in the video section even with all 3 heads up front its on video showing they do awful on a economy size Ford Focus.

There is no testing data that I know of where someone has tried to mount the recievers vertically. However with something as limited as an LED jammer I think it would really hurt performance.

Again I feel awful for you. Can you please let us know who helped you decide to go with a ZR3? Did you consider anything else? If you do happen to get a refund a single head Anti Laser would be ideal. it would be a very stealth install right under the bumper and because your car is black no one would even see it.

Best of luck.

I wouldn't go saying that it's a horrible unit, in the vids they only used one gun right and a old gun to boot! If I'm wrong here please correct me.

Thanks for the reply Staton. The ZR3 has performed well over the past few tests and by recommendations by members on this forum. I was not privey to a homemade test going on. I bought the ZR3 for $269 which was another factor in my purchase. Of course I considered something else, the Antilaser and Drive-Smart. However, their prices are twice as much, and there is too much BS to sift through to make a decision. I do not want to get this thread started on an Antilaser vs. Drive-Smart discussion because there is too much bias from certain forum members to discern the truth.

Either way, this is what I have to work with so lets proceed with helping me on a good mount. Is this the best mounting spot you can think of? How do other cars with non-level bumpers mount their heads? They must use these mounting brackets. Here is an install from my home forum that shows the same set-up.

Someone dissed the zr3 jammer same as my bel lp-905 jammer and i can tell you fron just today i had jam to gun-no reading and i went 58 in a 40 when nailed, i slowed applied brakes to slow to 50- then coasted off gas to 40, and entire time " front blocking" over and over and when i pass him he look at me and his gun and was wondering what happenned and it was great. anyways, dan these are great jammers, dont listen to the bad, there jealous or had a bad unit. i have a bel lp-904 from 2000 and there still hooked up and running. GODD BLESS AMERICA

need a real install-send email and ill mail mine to you. they didnt install correct for someone wanting 3 heads up front. i dont know how to send wout email address. then you will see.
with 3 heads, you want all 3 to fire back. you need to have them in a triangle almost in the middle. then the 2 fronts either below but closer to middle each of them. take a tape measure and as long as your front jammers are 18" away from side, your covered and in the middle is where they will usually strike first. but when 1 front goes off, they both fire but in order 4 the middle to fire, it too must be hit and since the 2 fronts werent closer to the rear(middle) they didnt all fire leaving you open. youdee have done better with that install with just 2 heads up front and the 3rd in back but hope you figured it out. mine works great. d

looks like options are limited for the BMW. Thats a beautiful car and i know you dont want to disface it to some degree. These challenges are always dificult.

I think the position of the two modules toward the outside are good, however the middle module should be level and horizontal not vertical, along with not obstructed from view of road. you need to find the way to get it right if you want all 3 up front.

If you use the 18"rule of thumb from center of each module and invision a circle you could pretty much determine the coverage and protection of your BMW's front.

Performance....
The ZR3 has worked well for me, i have had installed for 3 months now and only had 2 encounters in which it alerted and fired both front and rear (all 3 up front on my Mercedes ML320) mine was installed by Tweeters, believe me i paid for it, so was very particular as to positioning and stealth of the installation and cutouts in the grill.

When i get a chance i will post some pictures, for comments.

Take care and good luck.
