3D Design Quad Carbon Fiber Rear Diffuser BMW Z4 E89 35i 2010-2015
$1584.00

If you're looking to take your BMW Z4 E89 35i from just another car to something that really stands out, a rear diffuser is a game changer. It’s not just about looks—though let's be honest, the 3D Designs Diffuser does add a sleek, custom vibe that perfectly complements the Z4's curves. This piece is designed to cut down on air turbulence when you're pushing the pedal to the metal. At higher speeds, that means less drag, which translates to better stability. You’ll notice your car feels more planted, and it makes use of the horsepower and torque you already have, rather than fighting against the wind.

Now, let’s talk about what really makes this diffuser shine: its carbon fiber construction. We all know that weight is the enemy of performance. The lighter this diffuser is compared to the stock parts, the better your acceleration, throttle response, handling, and even braking will be. Plus, it helps with fuel economy—who doesn’t want that? Carbon fiber is a staple in the racing world for a reason. It’s not just light; it’s incredibly strong too. That unique weave pattern is something every car enthusiast recognizes, and it adds an undeniable flair to your ride.

And if you’re worried about the carbon fiber look not fitting your style, you can always paint over it to match your stock finish. Just a heads-up though: if you go that route, make sure to clear coat it. UV rays can be a killer over time, and you want to keep that diffuser looking fresh.

This diffuser is specifically designed for the 4-tip exhaust setup, so it fits right in with your existing setup without any hassle. If you’ve got a BMW Z4 from 2010 to 2015, this is definitely worth considering.

  • Features:
  • Lightweight design for improved performance
  • Durable carbon fiber construction
  • Fitment:
  • BMW Z4 E89 35i (2010-2015)

So, if you're ready to enhance your Z4's performance and style, the 3D Design Quad Carbon Fiber Rear Diffuser is a solid choice. It’s all about making your ride feel as good as it looks.

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.
