Carbon Fiber Trunk Lids

When BMW enthusiasts first saw the CSL trunk lid (or boot lid, depending on where you're located), installing a different trunk on your BMW has been a popular aesthetic upgrade. Enter the carbon fiber trunk. We love these because they set your BMW apart from the rest, while also saving you weight over your rear end.

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 say strongly that you are a car enthusiast, well so are we. 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.

What is an E36 M3 LTW?

In 1995, North America received a special gift: 126 production units of the E36 M3 Lightweight, also known as the "LTW." This limited-production, track-focused E36 was equipped with a range of features, including lightweight body panels, a stiffer suspension, upgraded brakes, and, notably, a distinctive style that served as functional aerodynamic enhancements.

Among its various enhancements, the exterior held the most distinctive features. Available exclusively in Alpinaweiss paint paired with an M-colored checkered flag, this car featured an adjustable front splitter and an optional high-rise spoiler. These elements not only contributed to its iconic appearance but also solidified its place in history as one of the most iconic-looking E36s to ever hit the market.

The LTW entered the states as a "spec" car; bare-bones, lightweight, and ready to hit the track straight out of the box. Alongside the track-focused vehicle came optional components separately packaged in the trunk. These included a front strut brace, chassis x-brace, deeper oil pan with a dual pick-up pump, and, last but not least, the GT rear spoiler (let's face it, it's an LTW spoiler). Interestingly, these components actually voided the warranty because they lacked DOT approval (maybe not the coolest aspect).

Overall, this package represented the epitome of coolness at the time, perhaps even among the coolest offerings directly from the manufacturer, ever.

How can Turner give you the LTW experience?

Over the years we have subconsciously engineered a full LTW package with our own spin on it to make your own LTW-esque E36. Among the upgrades, we have made an adjustable splitter kit packed with LTW styling(T#1871611), billet x-brace(T#4056343), street/track adjustable rear camber arms(T#304099), upgraded sway bars(T#359704), tubular race control arms(T#4524483), and many more suspension, engine, and exterior enhancements. The full suite of performance and aesthetic parts were not made in conjunction with one another; rather, it emerged from our enthusiast-driven desire to capture the track-focused essence of the LTW and apply it to our own E36s.

This CSL inspired trunk lid, made by Carbon Fiber specialist Carbon8, fits all 2007+ E92 3 series coupes and saves precious weight over the heavy steel stock BMW trunk lid. It also looks great, especially if you are into the naked carbon fiber look. This particular trunk lid's styling has a slightly swept up rear edge, reminiscent of the E46 M3 CSL -- which also had a carbon fiber trunk lid with an integral "spoiler" edge built into it.

We were pleasantly surprised by the fit and finish of this trunk lid, particularly at this price. The trunk lid fits as good as any other carbon fiber lid we've come accross. Some modifications and provisions need to be made to fit all trunk auxiliary components, such as lighting, trunk latch, hood shocks, emblems and interior trunk trim -- which is why we highly recommend professional installation on these (even if you're not having it painted). As with any carbon fiber or fiberglass body panel, extra time and preparation will be required to ensure the best fitment and installation. While no aftermarket body panels fit as perfectly as original OEM BMW panels, we were very satisfied with the overall quality and fit of these trunk lids. If you are mounting it unpainted to keep the carbon fiber visble, this trunk lid already comes with a clear gelcoat finish so that it is already exactly how you'd want it.

Professional installation highly recommended.

This carbon fiber trunk lid fits the following BMWs:
2007+ E92 3 Series Coupe - 328i, 335i & 335xi coupe
2008+ E92 M3 Coupe (2 door M3 only, no convertibles)

E36 M3 Street Flow Rear Diffuser

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 Black satin powder coat for long term corrosion resistance 5 piece design to simplify installation Slotted mounting locations to allow for mounting adjustment Laser cut ECS logo pre powder coat for a smooth finish Hidden hardware for better aesthetic
