The rear bumper that I received from Umnitza didn?t have the PDC holes drilled at all. Not only did my body shop drill the holes but they also took the little 2? or so PDC stands from the original bumper and plastic soldered them to the rep bumper. It took some extra effort but it turned out great.

The guys at umnitza are a bunch of idiots working there. I had a month long arguments via phone and email with "Tim" who doesnt have the slightest clue whats going on half the time. And then when you get on the phone with "Matt" he starts arguing with himself on the phone.
I have a e60 LCI, i paid for the full m5 kit and paid for fogs. they sent me a non-lci front bumper with no fog lights capability, no mesh grill and the head light washer bracket was too small to fit the housing on the uminitza front bumper. (At paypal checkout i put a little note on the comments section capaitalized "NO PDC, FOG LIGHTS CAPABLE, LCI")
If these idiots at umnitza only knew what it is like to live in a city where there is no access to a truck to get your bumper from the greyhound location to your body shop.
So ironb i feel your pain and next time think twice before buying anything from umnitza idiots.
Trinity all the way

I just recently bought a Umnitza M5 Body Kit. I'm having a local body shop paint and install the kit for me. Today they started the process of installing the new kit. They had no problem installing the front bumper. On the rear bumper they are having trouble installing the pdc sensors for the rear bumper as the holes are too small to fit the sensors from the oem bumper. The shop is looking into a solution for fitting the oem sensors since they can not just drill a bigger hole and pop them in. Also please be careful when ordering from Umnitza as they sell these bumpers as one fits all approach and obviously this is not always the case.
We acknowledge that the size of the holes is a problem, though it is a small one (pun kind of intended) and if you need further assistance - we'll be happy to discuss the remedy with the shop.
One very very important point here is for everyone to make sure the shop doing the work is test fitting and pre-fitting all parts prior to painting. If there is any mistake made on any shipment, we will be happy to work it out with you but we cannot do so when the bumper is painted.
That being said, see comments below for further validation that it's not as big a deal as the shop may be making it out to be. In the end, the bumper will fit perfectly and look very good and I will be happy to talk to the shop to help you make it so

When I ordered my m5 rear from Umnitza they told me that the hole would be too small, but wouldn't be hard for a good body shop to modify. My body shop just made the holes bigger. I'm pretty sure, from what I remember, that the sensors are just held in by friction from a snug fit. I also have an 07 550 and my body shop didn't have a problem modifying the bumper. Hope this helps.
The rear bumper that I received from Umnitza didn?t have the PDC holes drilled at all. Not only did my body shop drill the holes but they also took the little 2? or so PDC stands from the original bumper and plastic soldered them to the rep bumper. It took some extra effort but it turned out great.

Thanks for all your responses the shop is working through the issues. I will update the this thread once they have arrived at a solution. It would be nice if there was a disclaimer about the pdc fitting issue so I could have forewarn the shop before painting.

I finally got the bumper installed. It was not an easy task since the holes had to be enlarged after the bumper was painted. Currently one of the middle sensors will give a false reading. I will have to take it back to the shop to fix that. I'm feeling 50/50 on the exhaust tips right now. I'm thinking of switching them to dual ovals on each side. For the diffuser section has anyone done a mesh insert?

I had PDC issues last year with the Umnitza M5 rear. The hole in the bumper wasn't as issue in my case. The sensor would fit but all the readings would be flatlined like i'm about to hit something. At first I thought it might be reading the edge of the holes. This was NOT the case at all. These BMW sensors do have a left and right if that makes sense. They must go in, in a particular way. Umnitza's PDC brackets that hold the sensor are turned 45 degrees causing the sensors to instead read left and right, read up and down. the sensors are then reading the ground which causes it to give that "false reading". What I had to do was cut off the two tabs that hold the sensor to the bumper. I then rotated the sensor to the correct position and used so epoxy to keep them there. The flaw in this resolution is if I were the change bumpers I don't think i could remove my PDCs from the Umnitza M5 rear. Major design flaw in Umnitza's M5 PDC rear

And Yeah I'm not feeling the exhaust tips much, too much gappage going on there, other than that the kit looks pretty good.
