Here are some quick pictures. Overall the weave is good enough for what I paid for... cant expect perfection. One thing I noticed...there are no holes along the bottom of the diffuser. On the factory one, it looks like there are a series of screws holding it in place. Is there any good DIY's on this forum for this install?

Try to match holes of your stock one.

Yeah, I guess maybe fit the new diffuser, then mark where the holes need to be drilled so that it screws in properly to the rest of the underside plastics, then whip the diffuser back off and drill them. Either that or copy the hole locations from the old diffuser and hope that the new diffuser sits on the bumper in the same way.

Yeah this is what I will have to do. Shouldn't be too difficult. Thanks!

What's with the weird part in the middle? Was it made for a trailer hitch extension or something? Mine doesn't have that.

Quite a few seem to have that semi circle cut out. Not sure why.

Just an update on mine, I tried installing it the other day but, as a few have mentioned on here, the tabs were too thick. Gonna trim them down and try again this weekend.

What brand is yours? So yours has tabs similar to the stock one? Mine had those metal prong things that I had to bend once the diffuser was mounted to the bumper (which required me to remove my entire bumper cover...)




I will post install pics and the process I had to go through tonight.

Mine is from ScopioneUSA. They are not metal tabs, but they are supposed to mimic the plastic tabs on the stock valance. The problem is, they put too much resin/clearcoat on those tabs, making them too thick to go into the slots on the bumper.

That sounds like a pain in the ass. I suppose it's not too hard, but still... lame.

SO.... I installed my diffuser from Mod Bargains. .......

When I got the diffuser, the first thing I did was inspect the weave and hold it up to a light. The weave is far from perfect, but like I said, you cant expect perfection with these diffusers, thats why the OEM BMWP one is so expensive.
There are a few spots where the light shows through, but that is not such a big deal, since it is on the bottom of the car.

This diffuser has metal tabs on it, not the plastic ones on the Scopione and the OEM. These led to my first major issue.....



So I began by taking the stock diffuser off.



I quickly realized this job would be much more involved than I had planned. Those metal tabs need to be bent down once you mount it on the bumper cover to hold the diffuser in place. The problem with that is the tabs are so long that they hit the metal bumper of the car, and it was impossible for me to bend the metal tabs down from underneath the car. This is hard to explain and I was not able to take any pictures.

So my only option was to install the diffuser onto the bumper cover...off of the car. Great. Started by removing the tail lights and un screwing everthing underneath and in the wheel wells.



Removal of the bumper took me hours. I had no idea how the plastic tabs worked at first, and I did not want to pull to hard and break anything. The sides on the bumper cover have 4 clips. The only way to undo them is to slide the bumper cover backwards and pull it out. Once I figured this step out, it was easier and eventually came off...I did break one tab but it did not affect the fitment when I re installed it.



So now was the time to install the diffuser. It did not fit well...at all. I ended up having to Dremel the edges on the drivers side. Also, there were not any holes pre drilled so I did that as well. I didnt take any pictures of these steps, its pretty straight forward. Just keep grinding away and bend it until it fits in there. I ended up making it work, but it is still not perfect. The passenger side has a small gap. This photo also shows off the quality of the weave around the corner.



And a picture of a couple of the holes I had to drill, while under the car.



And 5 hours later...THE DIFFUSER IS ON THE CAR!



Now all that was left was to just screw everything back together under the car. The diffuser is solid as a rock. When I try to move it, it moves the entire car. Here are the final pictures, also showing off my newly installed LCI blacklines. Im still thinking about de-badging her.





I love how the Active Autowerk exhaust fits perfectly with this diffuser. It stuck out too far with the OEM one.



So the question is; was my trouble, the bad weave, the not perfect fitment worth the money saved off of the OEM BMWP diffuser? Im not so sure I can say yes. This was a major pain in the ass that took 6 hours of my day. By the sounds of it, the Scopione is the way to go, even with the tabs that you might have to sand down. At least you dont have to remove the bumper cover... I do love the way it looks, and I'm very happy the direction of the weave matches that of the BMWP spoiler. Well I hope this post helps some of you out if your on the fence of what diffuser to buy.

They may not be on eBay at the moment but they still have a website... And the best fit/finish of all the "cheapies"...
