Carbon Fiber Side Skirts vs Decklid Spoiler: Which Tesla Model 3 Upgrade First?

Category: Comparisons

Deciding between carbon fiber side skirts and a decklid spoiler for your Tesla Model 3? We compare the Vorsteiner Volta Aero pieces to help you choose which upgrade to do first.

Quick answer

If you want maximum visual impact from the side profile, start with the Vorsteiner carbon fiber side skirts. If you prefer a cleaner rear-end look with a subtle aerodynamic touch, go for the decklid spoiler first.

Visual impact and placement

The side skirts run the full length of the rocker panel, creating a lower, wider stance that's visible from every angle. The decklid spoiler sits on the rear trunk edge and is most noticeable from behind or in profile.

Both pieces use high-grade pre-pregnated 2x2 carbon fiber with a glossy finish, so the material quality matches. The choice comes down to where you want the eye to land first.

Aerodynamic function

Both Vorsteiner Volta Aero pieces are engineered to improve airflow, downforce, and drivability. The side skirts smooth air along the sides, reducing drag and helping channel air to the rear. The decklid spoiler adds downforce on the rear axle, which can improve high-speed stability.

If you track your Model 3 or frequently drive at highway speeds, the spoiler's rear downforce may be more noticeable. For daily driving, the side skirts' drag reduction is subtle but always working.

Fitment and compatibility

The Vorsteiner side skirts fit all 2017-2023 Tesla Model 3 trims, while the decklid spoiler fits 2017-2021 Model 3 trims. If you own a 2022 or 2023 Model 3, the spoiler won't fit, making the side skirts the only choice between these two.

Both are designed for a flush fit and finish, so installation should be straightforward for a shop familiar with carbon fiber parts. Expect to use automotive-grade adhesive for the spoiler and possibly additional hardware for the side skirts.

Trade-offs at a glance

  • Side skirts first: Start with the Vorsteiner carbon fiber side skirts if you want to transform the side profile and lower the visual stance. They work on all Model 3 years (2017-2023) and reduce drag for a small efficiency gain in daily driving. Best for visual impact and year-agnostic fit.
  • Spoiler first: Choose the Vorsteiner decklid spoiler if you prioritize rear downforce for high-speed stability and prefer a subtle trunk accent. Only fits 2017-2021 models. Best for highway/track driving, but check model year compatibility.
  • Do both: Combining both pieces gives a cohesive aero package with matched carbon fiber weave and finish. The total cost is around $2,183 before any discounts, and you get the full visual and aerodynamic benefit. Ideal if budget allows and your Model 3 is a 2017-2021.
