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!

Features:

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:

10 ga 5052 aluminum construction

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!

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

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:

10 ga 5052 aluminum construction
Black satin powder coat for long term corrosion resistance
5 piece design to simplify installation
Slotted mounting locations to allow for mounting adjustment
