Pre-Order Sale is live!

Finally, the perfect spoiler to complement the Highland’s style and performance.

  • Prepreg carbon fiber trunk spoiler
  • Herringbone weave at the center of the spoiler
  • High downforce for track applications
  • Straightforward installation

Fits these vehicles: Model 3  (2024+ Highland)

A more aggressive rear spoiler design aimed at producing downforce and looking incredible, all without being too excessive or wild. If our wing is a bit too much for you, this spoiler is your next best bet to improve the rear instability that the Model 3 is notorious for, especially at high speeds.

Our carbon fiber manufacturing is done entirely in-house at our sister company. These are not subbed-out parts to an unknown factory. In fact, at the time of writing, we’ve just taken delivery of a brand new paint booth to bring all of our finishing operations in-house. Carbon fiber manufacturing is exceptionally difficult, especially when using epoxy-based resins and high-performance resin light methods such as using pre-impregnated carbon fiber. This makes the parts extremely lightweight and strong, but it also means it’s easier to have voids that require more hand finishing.

These spoilers are on sale for our first production batch, and the sale price will be adjusted based on the overall quality of the products relative to what we consider to be a “perfect” part. This is your chance to save, but please note that any parts sold on sale have the potential to have minor blemishes or design aspects that aren’t 100% optimized. We sincerely appreciate your support as we expand (the hard way) into this area of composites manufacturing. With that said, please do NOT buy these parts if you expect a 100% perfect, blemish-free part with a totally perfect weave. We must admit that we’re likely not at that level yet, and we don’t want to disappoint anyone.

 

Concept And Design:

When designing our Highland Performance spoiler, we wanted something that accentuated the lines of the rear trunk and tailgate. Our goal was to extend the spoiler to keep the rear from looking “stubby”, while also giving the spoiler enough of a flare to produce a significant amount of downforce. In addition, we wanted the spoiler to securely attach to the backside of the trunk so that it wouldn’t detach from the aerodynamic loads it experiences. That then gave us the opportunity to perfectly match the curvature of the backside of the trunk, creating a beautiful flowing arc up from the back of the trunk and up into the spoiler.

What we have here is a design that we feel complements the Highland Model 3’s stylish and subtly aggressive front end by building out the ridge of the rear lip spoiler. Our design builds it out slightly, giving the spoiler more area to produce downforce, while respecting the curvature of the trunk and rear of the car. In many ways, the design of this spoiler is similar to the ethos with which we designed the Highland carbon fiber front lip.

Being a performance-oriented company, we obviously wanted to make sure that function was a major aspect of the product. For that reason, we’ve designed this spoiler to help fix the major weakness of the Model 3 at high speed – rear-end instability. The Model 3 is a car that is often set up to rotate – using large front tires and high camber, but this only makes the rear aerodynamic instability worse. Obviously a large wing solves this problem, but for most, a wing is too much for a road-driven vehicle.

Our rear spoiler adds enough rear downforce to give you the confidence to enter corners at high speed aggressively, even with “pointy” front-end focused mechanical setups.

 

Understanding Different Types Of Carbon Fiber:

There are some ridiculous names for Carbon Fiber in the automotive aftermarket. You may have heard terms such as “Wet Carbon” and “Dry Carbon.” In our industry, “Wet” carbon is typically referred to as a part that is made entirely of fiberglass with a polyester resin, finished with one layer of carbon on the visible surface for aesthetics only.

Dry carbon, on the other hand, is usually what our industry calls “Prepreg”. Prepreg is pre-impregnated carbon fiber. What this means is that the rolls of carbon fiber have the resin already built into the fabric, and only by heating the fabric to a high temperature does this resin flow out through the part.

Prepreg is the lightest and strongest way to make carbon fiber parts because:

  • You’re not making a part out of weak materials with a single layer of carbon for appearance only
  • You don’t have a weaker resin, such as polyester,r which isn’t nearly as strong as epoxy
  • You don’t have excessive resin in the part, which adds weight and no additional strength
  • You achieve the ideal carbon/resin mix

There’s a reason why all high-end structural and weight-conscious carbon fiber products are made using epoxy-based prepreg. F1, aerospace, lightweight racing bikes, etc.

However, it’s not all good news. Making prepreg epoxy-based carbon parts look good is MUCH more difficult than the “fake” fiberglass/polyester carbon approach. And yes, we’re going to call it fake because it is not real carbon fiber unless it’s ALL carbon fiber.

Some of the downsides and challenges with an epoxy-based prepreg part are:

  • Potential for yellowing due to UV exposure over the long term
  • Possibility to get “pinholes” in the part where there are minor areas where the resin doesn’t quite flow to the surface
  • Increased cost

Most motorsport parts will suffer from the above downsides. We are working very hard to address all of the downsides above by using the highest and best quality sealers and clear coats (the same finishes used by Singer, makers of the finest Porsche restorations in the world), working diligently with our prepreg suppliers to ensure we have materials that result in zero pinholes, while also optimizing for cost by not using more carbon than the part needs.

Thanks for your support while we learn this new craft and improve our offerings. While it’s much harder to scale up and do everything in-house, we are confident that this will allow us to offer the ultimate quality and value in the future!


What’s Included:

  • MPP Prepreg Carbon Spoiler with pre-installed 3M VHB adhesive tape
  • Adhesion promoter


Installation Details:

Installation is straightforward, however requires an experienced installer as some finesse is required with any double-sided tape installation. A full installation video and installation instructions are provided at the time of purchase. Removal of the OEM trunk is not required – the lip slips over the top of the existing front trunk spoiler lip and sticks on. Installation is actually very quick!
