Dramatic exits come standard with this carbon fiber upgrade. The multi-piece Dinan rear diffuser spotlights the rear of the car and creates a new "floor" that visually appears to make the vehicle lower and more aggressive. Despite the diffuser encompassing the exhaust exits, great care was taken to ensure enough room was supplied to accommodate even large tipped exhausts, like Dinan's own. Additionally, the diffuser adds wrap arounds to each of the rear quarters that allows a harmonious and uniform visual continuation with the Dinan front lip and side skirts for a perfectly matched cosmetic solution. Features: 2x2 gloss twill carbon fiber manufactured to be impact resistant, durable and strong Clear coated for maximum UV protection and fade resistance Includes 3M double sided tape and mounting screws for easy installation with a clean fit and finish

Seibon - Corporate Logo

Part#: RD0105BMWE46M3
Special Order: No Guaranteed ETA
$ 720.00 USD
$ 720.00 USD

Founded in 2003 Seibon Carbon excels in delivering premium quality carbon fiber products to those with discerning tastes. The process begins with the best carbon raw material manufactured in either USA or France; in fact it is the same stock that can be found on high performance racecars, battleships and satellites. Supporting race teams is one of Seibons' specialties and you will see their work in many different platforms and racing types. Drivers such as Michele Abbate in her Scion FRS racecar, Fredric Aasbo in his Formula D Scion tC and even team RS-R in Asian Formula D all rely solely on Seibon to get them to the podium.

Using single piece construction, the carbon is laid inside of a mold instead of being wrapped around it. This allows for a much stronger piece in the end and allows much greater control when the resin is applied. Areas such as door hinges, hood latches and window regulator mounting points are reinforced so as to add strength and longevity through repeated use. Application of the resin is then accomplished using proprietary techniques that allow for a much more uniform coating than most competitors and yields a product that is lighter, since there is no excess.

Finally the product is finished with a glossy clear coat this resists chipping and cracking and gives a glossy wet look. Inspection of the finished product is then performed to ensure there is no weave distortion in tight corners or complex bends.

Features:

  • Proprietary methods to lay wet carbon for a stronger and lighter product
  • UV resistant resins, even a weathered part can be wet sanded and brought back to original finish
  • Panels are 70% lighter than stock as opposed to competitors which come in around 50% lighter than stock.
  • No black paint is used to hide imperfections along detail edges and creases.
  • Partnered with SCCA and Formula Drift bringing their top quality fit and finish to the competition environment.

This item fits the following BMWs:

Enhance the rear of your BMW M3 G80 | M4 G82/83 with the new VR Aero carbon fiber rear diffuser. Carbon fiber diffusers have been a popular upgrade for many years on almost all the BMW M3 variants. Its a great way to further accentuate upgraded exhaust systems and give the M car a more stout look.

VR Aero set out to achieve perfection by delivering precise fitting carbon fiber that requires no modification to install. The elegant 2x2 (3K Twill Weave) will grab your eyes and draw you closer to the glossy finish that shows the depth of the weave.

ECS Exclusive Proudly Offered at Turner Motorsport!

Add-on diffuser to deliver a true motorsport look to your M3. Fastened seamlessly to the bottom of the rear bumper giving a platform to show off your exhaust and complete the rear end of the E92.

The E92 M3 is an amazing looking car right out of the box but a common BMW issue is the height of the front vs rear bumpers. As far back as the E30, the front bumper is much lower than the rear bumper and the E92 M3 faces the same issue. With this problem the front bumper is always super low to the ground and the rear bumper looks in-complete. The ECS add-on diffuser is a unique option for balancing out the rear bumper with the height of the front bumper for a full and complete look. The E92 diffuser also features an optional center fin design to dial in the aesthetic you prefer!

Give your M3 that wild style that stands out from the crowd, and obtain a nice balanced look. This is just the start of a new line of Street Flow Diffusers diffusers that are a must have extension of your awesome ride. The diffusers come powder coated in a sleek satin-black finish, are a blast to install and fit seamlessly against the rear bumper for a professional looking install every time. The Street Flow diffuser attaches below your factory rear diffuser and exhaust of your choosing to fill out the rear end for a nice full and aggressive styling profile.

Lets take a trip together down a new and unique path. Over the years ECS has designed factory replacement ABS and Carbon Fiber diffusers for all different models of BMW's. For the factory replacements ECS focus was to take the oem characteristics and add a twist and really bring out a more aggressive look with a direct replacement diffuser. For their new line of diffusers, us as car enthusiasts wanted to design a set of diffusers that really pushed the envelope and stepped outside of the comfort zone. ECS's new line of add-on diffusers is a result of the engineering team and fellow enthusiasts spending time study the M3 chassis, modeling different designs, testing prototypes and making changes to get a final product that we are extremely excited to offer. The E92 M3 Street Flow Diffuser is part of a new line of diffusers. Check out the diffusers in the line-up including the E36 and the E46 M3 variations!

Features:

Optional center fin included
Adds an aggressive aesthetic in addition to the subtle factory rear diffuser
Lightweight and durable 10ga aluminum in satin black powder coat to blend with the factory trim color
Installation is secure and simple with ample adjustability built in for perfect fitment
Design:
