3D Design Quad Tip Exhaust Carbon Fiber Rear Diffuser
$1695.00

If you’re looking to take your BMW to the next level, the 3D Design Carbon Fiber Rear Diffuser is a game changer. This isn’t just some flashy add-on; it’s a serious piece of engineering that can help your car handle better at speed. When you’re cruising down the highway or hitting the track, the rear diffuser works hard to cut down on air turbulence. That means less drag and more stability—your ride feels planted, and you can actually feel the difference as you push the pedal down.

What’s cool about this diffuser is that it’s not just about performance; it also gives your BMW that sleek, custom look. The design flows perfectly with the lines of your car, enhancing its overall aesthetic without looking out of place. If you’ve got a 4-tip exhaust, this diffuser fits like a glove, making your rear end look sharp and aggressive.

Now, let’s talk materials. This diffuser is made from carbon fiber, which is a big deal in the car world. It’s super lightweight compared to the stock parts, which means better acceleration and improved throttle response. You’ll notice your car feels more responsive when you’re driving. Plus, it’s strong—carbon fiber can take a beating while still looking good. The unique weave pattern is something that car enthusiasts recognize and appreciate, and if you’re feeling adventurous, you can always paint it to match your vehicle’s color. Just remember to add a clear coat to protect it from UV rays; you want to keep it looking fresh for as long as possible.

This rear diffuser isn’t just for show; it’s a smart upgrade for anyone serious about performance. It fits perfectly on the BMW 4 Series F32 M Sport 435i (2014-2015), and it’s also compatible with the BMW 428i (2014-2016). If you’re ready to enhance your ride’s performance and style, this is one upgrade you won’t regret.

  • Lightweight for improved handling and performance
  • Carbon Fiber Construction for strength and a killer look

About 3D Design

Founded in 1998, 3D Design is a Japanese-based performance and styling company focused on BMW models. 3D Design was established by a knowledgeable team with extensive experience and proven technology through participation in various races across various categories, in both domestic and international circuits. 

3D Design’s philosophy is to strive for perfection and accuracy in everything it does. It takes pride in placing a lesser focus on the time and cost of developments, which is reflecting in the brand’s quest to build the most attractive and efficient tuning and aerodynamic parts for the niche BMW performance market. For the last 20-plus years, 3D Design has remained true to its mission to develop products that are beyond industry standards and customer expectations. Each and every product that bears the 3D Design stamp is full of racing spirit and was manufactured with a focus on drivers and what they demand for their vehicles. 

What Does 3D Design Offer?

3D Design’s core market is aerodynamic components such as carbon diffusers, bumpers, splitters, and spoilers. All of its products are manufactured in Japan and adhere to stringent guidelines. 3D Design develops and produces high-quality, reliable automotive parts for a wide range of applications – for use on the streets all the way to the circuits. Every single product is made with the end user's desires and needs in mind. 

For example, when developing its suspension systems, the company’s prototypes undergo repeated rigorous testing on the streets and the windings of race circuits to ensure its quality, durability, and performance. When 3D Design developed its urethane spoiler components in 2004, they were built to the highest degree of accuracy possible. No cost or time was spared in order to achieve such a high level of perfection. What’s more, eco-friendly materials were considered for the end of the product life cycle as well. 

3D Design offers a plethora of unique styling components for every single BMW series. In addition to aerodynamic parts, 3D Design also manufactures wheels, springs, brake pads, pedal kits, exhaust systems, high-flow intakes, professional gauges, and several other accessories. All 3D Design products feature ultra-high-quality manufacturing and superb fitment for maximum performance benefits and longevity.
