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 E36.

The E36 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 E36 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.

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 our comfort zone. Our new line of add-on diffusers is a result of our 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 E36 M3 Street Flow Diffuser is the first in our line of new diffusers. Stay tuned for the E92 M3 diffusers next!

Unlock Aggressive Style with Turner Motorsport's E36 M3 Street Flow Rear Diffuser Kit & ABS Front Lip!

Achieve an aggressive, cohesive design that enhances your M3's exterior appeal from front to back.

E36 M3 Street Flow Rear Diffuser

The E36 M3 has always been a head-turner, but the rear bumper often lacks the levelled look of the front. With BMW's signature design featuring a lower front bumper compared to the rear—an aesthetic seen across generations—this diffuser brings balance by matching the rear bumper’s height to the front, giving your lowered E36 M3 a sleek, grounded look.

Designed to add a bold edge to your M3, the Street Flow Diffuser is our latest innovation in aggressive styling, specially crafted to bridge the gap between factory lines and custom flair. Each piece is precision-engineered and powder-coated in satin black to perfectly complement the M3's factory trim. Easy to install, the diffuser seamlessly mounts to the rear bumper, ensuring a flawless fit and professional look.

The Street Flow Diffuser is a new venture for Turner Motorsport, diverging from our line of factory-replacement ABS and Carbon Fiber diffusers to deliver a design that pushes the boundaries. After extensive modeling and prototyping, we’re thrilled to debut this product, with more designs in the pipeline. Get ready to take your E36 M3 down a unique path in styling evolution.

Key Features:

Bold Appearance: Complements the OEM rear diffuser with an added aggressive look. Durable Construction: Made from lightweight 10-gauge aluminum, finished with a satin black powder coat for superior durability. Effortless Install: Adjustable slots and hidden color-matched hardware for a streamlined setup. Specifications:

Material: 10-gauge 5052 aluminum with black satin powder coat Design: 5-piece layout for easier installation and maximum fitment adjustment Extra Detail: Includes laser-cut ECS logo and concealed mounting hardware Turner Motorsport ABS Front Lip - Matte Black

An essential upgrade, this ABS Front Lip brings both visual impact and aerodynamic benefits to your M3. The front lip adds downforce for enhanced handling while maintaining a durable build to withstand daily driving conditions, including road debris and uneven surfaces.

Inspired by the E36 LTW design, Turner Motorsport’s ABS Front Lip is a cost-effective alternative to fragile carbon fiber lips. Made from UV-stabilized ABS plastic, this two-piece design resists cracking and shattering, offering a matte black finish that complements the original E36 aesthetic. For added versatility, this lip can be prepped and painted to suit your style preferences.

Features & Specifications:

Inspired Design: E36 LTW-inspired look in a robust ABS form Enhanced Durability: UV-resistant construction for long-lasting performance Precision Fit: Engineered using 3D laser scanning for optimal fitment Easy Install: Uses factory screws and includes pre-applied 3M adhesive for extra security Upgrade your E36 M3’s style with Turner Motorsport’s rear diffuser and front lip combo, adding aggressive lines that turn heads on the street and track alike!

E36 Sedan LTW Spoiler:

Experience a modern interpretation of LTW styling with our latest creation. Inspired by the classic E36 lightweight, and crafted with precision by our expert engineering team at Turner, we proudly introduce our carbon LTW spoiler, setting a new standard in the industry. Carefully crafted with a multi-piece carbon design, our spoiler is not just an accessory; it's a work of art featuring a flawless glass-like finish and perfectly matched carbon weave.

As fellow enthusiasts, we understand the importance of preserving the integrity of E36s and their components. With iconic colors like Techno Violet, Boston Green, and Estoril Blue in mind, we refuse to compromise the original trunk and paint with traditional drilling methods. Instead, our carbon LTW spoiler features an innovative fastening system that requires no modifications and preserves your car's pristine showroom finish. With precision-engineered billet clamps and high-quality 3M double-sided tape, installation is a breeze, requiring only basic hand tools. No drilling is necessary.

Research and development:

We feel it is crucial to share our journey into the design and engineering that went into developing this remarkable carbon spoiler. The development of this LTW spoiler was not a quick process; it spanned over three years. Throughout this time, we dedicated ourselves to refining, testing, and making adjustments to craft a spoiler that we're thrilled to introduce to the community.

From perfecting the form and fitment to ensuring the spoilers's stability, every aspect of this project presented significant challenges. This carbon spoiler is comprised of 5 components, the base spoiler, 70mm risers, upper spoiler, gurney flap, and most importantly the mounting brackets.

Anyone familiar with carbon fiber knows the difficulty of working with these nearly 50-inch wide pieces to achieve straightness without flex while maintaining a consistent carbon weave pattern. During the initial stages of carbon testing, the manufacturing process proved to be nothing short of impossible. Issues such as carbon fiber twisting during curing, waviness in the exterior appearance, and mismatched carbon weave posed significant hurdles.

Furthermore, ensuring precise fitment was paramount. Not only did the spoiler components need to seamlessly integrate with the trunk gaps, but they also had to clear adjacent body portions without error. We underwent rigorous testing, cycling through five sets of carbon spoiler prototypes before achieving a result that met our exact standards.

Numerous adjustments were made throughout the project, including modifications to the carbon composition, bracketry, and the incorporation of gaskets between carbon layers. Our passion and dedication were poured into every aspect of this product.

Throughout the project timeline, we conducted extensive long-term testing on various vehicles, subjecting the spoiler to speeds beyond what can be publicly disclosed. When we say these spoilers are secure, we mean it. Utilizing both 3M double-sided tape and four billet brackets with a total of eight fasteners, this spoiler can be confidently installed. The billet mounting brackets are designed to fasten over the top of the factory seam sealer on the underside of the trunk for maximum stability. Near the end of testing, we decided to add an adhesive-backed gasket to the underside of the base, providing yet another layer of paint protection.

Styling:

The greatest part we have enjoyed over this project is the versatile style of the spoiler as designed. If you have read this far into our development process we can strongly say that you are a true car enthusiast. As car enthusiasts we can never leave the car alone, changing setups and most importantly styling. With the multi-piece design, the option to change up your look is just moments away with a little help from some hand tools.

Initially, we were fully committed to running the complete setup: full height, 70mm risers, and gurney flap – all inspired by the LTW look with a modern carbon twist. However, as we spent more time with the spoiler, our perspective shifted. We decided to remove the 70mm risers and suddenly rediscovered our love for the E36's original aesthetic. Without the risers, the spoiler took on a new, understated elegance, blending seamlessly with the car's overall design.

Time passed, and we began to explore other options. Removing the gurney flap toned down the race car vibe, revealing yet another layer of the spoiler's versatility. Each subtle alteration brought about a significant change in style, proving that even the smallest adjustments could make a world of difference.

Our journey with the spoiler was one of constant evolution; from full-on LTW racing aesthetics to more understated styling and back again. This flexibility was the true beauty of our creation, keeping us engaged and dedicated throughout the rigorous development process.
