    Perfect for Carbon Fiber Enthusiasts. I already have several carbon fiber upgrades on my type 42 R8 V8, and this diffuser was the missing piece. It matches perfectly with other CF parts, and the quality is exceptional. If you’re a carbon fiber enthusiast, this is a no-brainer!

    Looks Like a Supercar Now! After installing this Scopione carbon fiber rear diffuser, my 2010 R8 V8 Coupe looks even more exotic. The quality is OEM-level, and it gives the rear end a meaner, more aggressive stance. I highly recommend this to anyone wanting to upgrade their R8’s aesthetics and aerodynamics.

    Great Quality, But Took Some Adjustments. The carbon fiber finish and build quality are top-notch, and it definitely gives my 2009 Audi R8 V8 4.2L Coupe a more aggressive look. However, I had to make some minor adjustments during installation to get the perfect fit. It wasn’t a deal breaker, but I expected a more seamless installation for the price. That said, once installed, it looks fantastic and really enhances the rear end of the car. Would recommend, just be prepared for a bit of tweaking if needed.

    Absolutely Transforms the R8 – A Must-Have Upgrade!

    I’ve been modifying my 2009 Audi R8 V8 Coupe for a while now, and this carbon fiber rear bumper diffuser from Scopione is easily one of the best upgrades I’ve done. From the moment I unboxed it, I could tell the quality was exceptional—the carbon fiber weave is flawless, the clear coat has a deep gloss, and it just screams premium craftsmanship.

    Fitment & Installation:
    I was initially concerned about fitment since some aftermarket carbon fiber parts require adjustments, but this diffuser fit perfectly right out of the box. The pre-drilled mounting points aligned precisely with the stock locations, making installation quick and hassle-free. I installed it myself in about an hour with basic tools, and I didn’t have to make any modifications.

    Appearance & Aesthetic Impact:
    Once installed, the transformation was incredible. The diffuser adds a more aggressive, track-inspired look to the rear end while maintaining a sleek and OEM-like finish. It complements the R8’s natural curves perfectly, and I’ve already gotten multiple compliments at car meets. The glossy carbon fiber finish also matches my other CF components, which really ties everything together.

    Performance & Functionality:
    Beyond aesthetics, I noticed a slight improvement in rear-end stability at higher speeds, likely due to the diffuser’s aerodynamic design. While it’s not a massive performance boost, every bit helps when you’re pushing the car to its limits. Plus, the lightweight nature of carbon fiber means I’m shaving off unnecessary weight.

    Final Thoughts:
    If you own an 08-12 Audi R8 V8 Coupe or Spyder, this carbon fiber rear diffuser is a must-have upgrade. The quality, fitment, and overall impact are worth every penny, and it truly gives the R8 a more exotic, supercar-like presence. Scopione nailed it with this product, and I’d highly recommend it to anyone looking to elevate their R8’s rear-end styling and aerodynamics.

    Pros:
    – Perfect fitment – No modifications needed
    – Premium-quality carbon fiber – Uniform weave & deep gloss finish
    – Easy installation – Pre-drilled holes & proper alignment
    – Aggressive yet elegant styling – Transforms the rear end
    – Lightweight & aerodynamic – Slight performance improvement

    Cons:
    – None – Just be ready for some jealous looks!

BMW M5 Front Kidney Grille and Eyelids by Scopione

Had the Scopione eyelids and the front front grille for over a year now, still love the look as I did the day I put the parts on.

Had a problem with one of the eyelid that came off the headlight, due to the horrible double sided tape that my installation shop used. Had Scopione send me out a replacement eyelid, greatly appreciate for taking care of me with that, and not making me get two new ones. So I came back to the shop, but with some new knowledge about installation from Stan at Scopion this time. Made sure the shop cleaned the surface on the headlights with soap and Windex, then they used 3M windshield silicon to attach the eyebrows back on. No issues since then. Wish I asked from the start about the installation, but overall awesome products and reliable company, thanks again.
