*New* JL-Motoring "GTS Style" CF Sedan Diffuser
Wanted to share my experience and let everyone know about JL-Motoring's new Carbon Fiber Diffuser offering for the E90 M3 Sedan.
So I have been shopping around trying to find a diffuser for the E90 M3 that I liked enough to purchase. On my previous car I had the Vorsteiner Type 2 Diffuser which I liked, but it wasn't ever as nice as those that i've seen on the coupe. I wanted to try to find something different from the normal E90 offerings while still remaining affordable. I started looking at "replica" options since most of the name brands were priced higher than I felt was reasonable for a piece like this and JL Motoring was the first that come to mind. In the past I had ordered CF front splitters from them for my previous M3 as well as a friends' E90 M3. When I originally started my search, JL Motoring had only 2 diffuser options for the sedan (unlike the e92 m3 which has many variations), the Type 2 Style that I previously had which only surrounds the inner exhaust portion of the bumper, and a full length version with fins that were extremely small and not visible, which I really didn't like. I felt like I was going to have to settle for one or the other and was kind of bummed out. Eventually I decided to bite the bullet and just purchase the Type 2 Style diffuser. Went online to buy, and Lo and behold I came upon this new offering which I have never seen before... The GTS Style Diffuser. It looked exactly like what I wanted. Contacted JL via PM and scheduled a time to drop by their office and pickup the diffuser same-week. Link to product: http://www.jl-motoring.com/BMW_E90_M...p/bmdi9056.htm On to the pics, and I will follow up with the overall review! . . As you can see, the quality is pretty damn good for a "replica" part. Weave is clean, and the piece is solid, yet light. Quality is better than what I expected. Not 10/10 OEM, but not the typical 5/10 reproduction pieces you may find elsewhere. Note: this is a CF overlay on top of FRP, not full CF. On to the install: JL Motoring was nice enough to provide me with two single-use 3M Primer 94 sticks. This is an "adhesive promotor" that helps the double sided tape stick better to both the bumper and the diffuser. You simply crack the bead on the stick by squeezing, and rub the "brush" end along the area you are going to apply the tape. I did this on both the diffuser as well as the bumper. Here's my OCD Tape job: Test Fitted & Drilled Out Inner Mounting Holes: Note: The screw in mounting tabs are not pre-drilled on this part [see pic 2] So I placed the diffuser up against the bumper without the tape and aligned it properly to test-fit with some plastic clamps. I then drilled out the correct sized holes for the OEM screws to fit properly. Unfortunately the only part of the diffuser that didn't fit were the two outer mounting tabs. The outer tabs are very strong, so they aren't flexible enough to be flush with the screw holes, they need about 5-10 degrees of more inward angle to line up properly with the screws and be able to be drilled properly. I simply just left them unscrewed as I was confident with my tape job and think it will still hold on well. I may try to redress this and find a way to have them screw in. All done! . . Overall after going thru the install process I would definitely recommend this diffuser to all you E90 M3 owners out there who are looking for an alternative to the typical diffusers that you see here all the time. Install was fairly simple and easy for anyone patient and mechanically inclined. Weave as you can see is very good. I'd rate this product an 8/10 overall. 10/10 being OEM, and 1/10 being the diffuser that I went to pick up a couple months ago which was produced by the well known Extreme Dimensions. I opened up 3 of them to inspect before just leaving the warehouse empty handed. Fitment and weave was atrocious. All in all, highly recommended and JL Motoring was very nice, communicative and great to deal with!

Thanks for posting this...it looks damn good dude! Nice to see another option for us E90 guys.
This rear diffuser is almost perfect to me in terms of looks. I just wish the outer edge on each side popped out more like the Arkym style diffuser opposed to being pretty flat the way it is now. Otherwise, it looks great! Props to JL-Motoring...they're definitely one of the top rep cosmetic part companies out there now for their products and customer service!

I also spoke to JL about this diffuser a couple months ago, as it was a cool looking alternative to whats available at the same price point. It looks like fitment is pretty damn good, but i wish the contour of the outer part of the bumper was raised up like DJ_DUB is saying.
still waiting on a nice rep of the 3dDesign rear diffuser, as the current reps dont look good at all... |

Thanks guys.
Only minor hiccup I am having is that my aftermarket tips are a tad too big. lol. The outer drivers side tip is just barely touching the inside of the diffuser, so i'll need to space out the mounting point a bit to push the tips inwards a bit more. Other than that, all good!!

I think my search for a diffuser may be over. This one is beautiful and the price is right, so happy I stumbled on this thread. I might need to put different tips on the Borla ATAK exhaust I'm getting, so that they fit... but, that's okay. I kind of wanted to switch out the tips anyways.
Great write up man! Seeing such positive feedback about this diffuser pretty much sealed the deal for me |

Love this diffuser! My first love was the 3D designs E90 rear diffuser but not the price so I opted for the AKRM rep. This GTS looks very similar to the 3D design with it's flush fitment with the exception of the middle fin. I think I'll be pulling the trigger on this diffuser and get rid of my current. Great write-up and it looks phenomenal!

Nice write up... difffuser looks great! I might have to pull the trigger on this. This would look good with their arkym style fronts... not overly aggressive and not subdued... just right. By the way, which trunk lip is that? and are you running any side lips?
