If you're a BMW F90 M5 owner, you know how important it is to get the details right. That’s where 3D Design comes into play. Since they kicked things off in 1998, they’ve been all about creating top-notch suspension components and killer aero parts that really make your ride stand out. They’ve expanded their lineup over the years, adding lifestyle accessories and interior bits, but their heart has always been in performance and style. Trust me, these guys know their stuff.

Now, let’s talk about their Carbon Fiber Rear Diffuser and Rear Under Splitters. This set isn’t just about looks; it’s about precision and performance. We’re talking fully prepreg 2x2 twill carbon construction here, which means it’s not only lightweight but also super sturdy. You’ll notice the flawless carbon weave that 3D Design is known for, and it fits snugly onto your M5’s rear bumper, giving it that aggressive edge without compromising on quality.

  • The set includes both the Rear Diffuser and Rear Under Splitters (part numbers 3108-29011 & 3106-29011), so you’re getting a complete package.
  • Installation is straightforward; you’ll get all the hardware and instructions you need to get this beauty mounted up.

Just a heads-up: if you’re used to the hands-free tailgate opening feature, it won’t work with this diffuser. But honestly, the look and performance boost you get from this upgrade is totally worth it.

In terms of fitment, this is designed specifically for the BMW M5 from 2018 to 2023. If you’re rocking one of those models, you’re in luck. You’ll clear the 35s with just a bit of trimming, making this a solid choice for anyone looking to enhance their ride’s stance and performance.

So, if you’re ready to take your M5 to the next level, check out the 3D Design Carbon Fiber Rear Diffuser Quad Set. It’s all about the details, and these guys have nailed it.
