There's something about a High Kick Trunk Spoiler that makes an E46 Coupe look even better! Going off of our design from our original Carbon Fiber High Kick Spoiler, we have developed an ABS High Kick Trunk Spoiler that transforms the look of your E46 coupe, all while keeping budget constraints in mind. Constructed from impact and UV resistant ABS plastic, this light and durable spoiler provides a sporty style that's sure to set your vehicle apart from the rest, without the high price of an equivalent carbon fiber spoiler. Installs with no drilling, cutting, or any permanent modifications! Included are two pre-mounted double side adhesive strips for easy installation onto your trunk lid. Simply clean the surface area of the trunk, remove the backing from the already attached high strength double-sided tape, line it up, and press firmly down. We recommend doing this in a warm environment as it will better adhere to the trunk. Features & Specifications: Designed and engineered by Turner Motorsport in-house using state of the art 3D laser scanning and CAD technology for precision fitment. Mimics the design of our carbon fiber version as closely as possible for similar styling. Accentuates the OE body lines throughout the outer edge of the spoiler Utilizes 3M double-sided tape for a strong bond to the body Made from lightweight, vacuum-formed gloss black ABS polymer that is enhanced with UV-stabilizer

Our unique and carefully designed front lip for the E46 M3 focuses on enhancing the car's aesthetics while preserving its natural beauty.

This aesthetic piece was crafted to stand out from other options available on the market by incorporating design elements that draw inspiration from the stock bumper but reimagines them in a way that sets it apart. Rather than overcomplicating the car's body styling, the goal was to seamlessly integrate the front lip with the existing design. This approach aims to enhance the car's body styling rather than overshadow it.

This versatile design is suited for both track use and everyday driving on the streets. Our E46 M3 front lip was designed to strike a balance between uniqueness and performance oriented aesthetics, while complementing the car's existing design. This is a clear cut choice front lip for someone looking to enhance the look of their M3.

Once you see your M3 with this front lip from, you will no longer think the front end is complete without it. Rounding out the near perfect car, this front lip completes the front end by filling out the open space underneath and sets the stage to enjoy the timeless body styling incorporating a curvature that compliments the front bumper.

Features & Benefits:

Motorsport styling
Enhanced lowered appearance
Installation hardware included
Crafted of UV stabilized ABS polymer
CAD designed in-house for precision fitment
Designed to fit with both the factory skid plate and the Turner Motorsports upgraded skid plate
Installation:

Mounts to the bumper using factory hardware combined with self tapping screws, plastic specific rivnut and hardware for securing the center posts. Requires drilling the underside of the bumper.

The E46 M3 CSL sparked a lot of interest among enthusiasts about the "high kick" look. But what about those who want the aggressive, high kick look without having to replace the entire trunk? We found ourselves scratching our heads, especially unsatisfied with the add-on CSL spoilers you can find on the market.

We took it upon ourselves to CAD design an aggressive, high kick spoiler that pays homage to the CSL trunk, while flowing perfectly with the simple, yet aggressive body lines of the E46 coupe. The carbon fiber is hand laid, with a beautiful gloss finish that will match well with any other carbon fiber accents on your E46 coupe. Our high kick rear spoiler will instantly give your vehicle a more aggressive look.

These replacements are easily installed and dramatically change the appearance of your vehicle. Our body colored reflectors are actually the same original reflectors that currently sit in your cars bumper, but are painted the exact color of your vehicle by a CERTIFIED PROFESSIONAL REFINISHER, so that they blend in perfectly with your bumper. No glue or adhesive of any kind is required to install these reflectors, they simply snap into place into the same holes as your originals.

Note: Paint will match the color of a brand new vehicle painted in that color. On certain colors, exposure to the sun will slightly change/fade the color of the vehicle, especially with older vehicles or vehicles in warm climates. Foroff road use only!

These reflectors fit the PRE-FACELIFT (2000-2003) Coupe and all E46 M3.

IF YOU DO NOT KNOW YOUR PAINT COLOR : If you open the hood you will
find that on one of the shock towers, probably passenger side, there will be a
black label, on this label will be the color name written in German along with
the paint code number at the bottom. Only the numbers before the / are required.
This is your paint code.

Aero upgrades are undoubtedly one of the most visually striking enhancements you can make to your vehicle. A carbon fiber front lip, in particular, is a popular choice that instantly elevates the car's appearance, making it stand out from the crowd.

However, this bold aesthetic upgrade has its challenges, especially when navigating uneven roads or steep driveways that can potentially damage the expensive carbon fiber. Luckily, Acexxon offers a solution to safeguard your valuable lip from scratches and more serious damage, allowing you to fully enjoy the upgrade without worries.

The Acexxon kit comprises five 18-inch strips that securely attach to the underside of your lip using pre-installed 3M double-sided tape. Three of these strips feature a smooth end, seamlessly blending with the front lip's leading edge. The remaining two strips are designed with contour flex sections, ensuring a precise fit around the lip's curved contours. Compared to other kits, Acexxon's design minimizes trimming requirements, needing only the trimming of excess material at the lip's ends for a flawless finish.

Key Features:

Includes 5 strips Each strip measures 18" in length and 1.75" in width Thickness of 5.47mm Equipped with pre-installed 3M tape for easy installation

The GTR Designed E46 Carbon Fiber Hood is an aftermarket upgrade tailored specifically for the E46, combining both aesthetic and performance-enhancing features. Crafted from premium carbon fiber material, the hood offers a blend of lightweight construction and high strength. Carbon fiber not only enhances the visual appeal but also reduces overall vehicle weight, which can lead to performance improvements such as enhanced acceleration, handling, and fuel efficiency. The GTR design cues add a bold and aggressive aesthetic to the E46, giving it a more track-inspired appearance. The carbon fiber weave pattern further enhances the visual appeal, adding a touch of sportiness and sophistication. Features heat ventilation. These vents can help dissipate heat more efficiently from the engine bay, reducing temperatures and potentially improving engine performance, especially during spirited driving or track sessions. Beyond its visual impact, the hood's design may also contribute to improved aerodynamics by reducing lift and increasing downforce at the front of the vehicle. This can enhance stability at higher speeds and improve overall handling performance. Key Features: Material: High-quality carbon fiber (Fiber-reinforced Polymer and Glossy Carbon Fiber Coating) Precision Fitment: Designed for the E46 chassis for seamless integration Lightweight: Carbon fiber lightweight designed Aerodynamic Enhancement: Improves airflow and downforce for better stability Sleek Design: Adding a cooling factor to keep your engine temperatures down We encourage customers to seek professional installation since equipping these products will require the removal of parts currently installed, to better secure fitment to your vehicle.

This is a high quality reproduction of the Euro-only model E46 M3 CSL style front bumper cover spoiler. Unlike the stock E46 M3 style bumper, this CSL style has no fog light openings, and a single duct on the driver's side that can be made to function as a cold air intake inlet/duct. The bumper is made of polypropylene (PP) plastic, just like a factory BMW bumper covers. It also features pre-installed carbon fiber lips, very much in keeping with the factory CSL part. Best of all, this CSL-inspired bumper is available for only a fraction of what a real CSL bumper would sell for -- the BMW dealers themselves are forbidden from ordering genuine CSL parts anymore, making the "real thing" even harder to come by. This bumper comes as shown, primed ready to prep and paint. Includes US license plate mount (bumper is pre-drilled to accpet the license plate mount). The screen for the intake hole is not included but can be added from the options below. Professional paint and installation is highly recommended.

This M3 CSL style bumper can be used on the following BMWs:

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 E46.

The E46 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 E46 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 E46 M3 Street Flow Diffuser is the first in our line of new diffusers. Stay tuned for the E36 M3 and 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

This CSL inspired trunk lid for 1999-2006 E46 3 series Convertibles 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 across. 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:  
1999-2006  E46 BMW   Convertibles 323Ci 325Ci 328Ci 330Ci

When the E46 M3 CSL was released, one of the central talking points of the vehicle was the cutting edge weight saving technologies that were utilized in its construction. The CSL was most notably distinguished from the standard E46 M3 by its various lightweight components. The largest of these is the carbon fiber-reinforced plastic (GFP) roof panel, which weighs over 13 pounds less than its conventional steel counterpart. Many enthusiasts sought after the BMW OEM roof to add to their vehicles, but the part was and is to this day only available to those with a CSL vin #. As an answer to the E46 M3 clients, RKP is proud to introduce the RKP E46 M3 carbon fiber roof panel. Their carbon roofs are constructed by hand at a local facility specializing in components for Grand Am, Time Attack, and various hill climb and formula car classes. Each roof has great fit and finish and saves a considerable amount of weight over the standard roof panel.

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.
