Tesla Model Y Performance (2026+) Full Aero Kit

Tesla Model Y Performance 2026+ Full Aero Kit

The Model Y Performance Aero Package is a complete front to rear system for the 2026+ refreshed (Juniper) generation. Each part integrates easily to make installation clean, fast, and fully reversible. The result? A sharper OEM plus appearance with real aerodynamic benefits you can feel when you’re out on the highway, daily driving, or the occasional PR chasing lap times on the track. This package is designed to work as a system. It manages how air meets the car, travels underneath and along the sides, and leaves at the rear, improving stability and efficiency while preserving the original design language.

Validated by CFD

Every component was shaped and refined using computational fluid dynamics (CFD). The spoiler and diffuser pairing was tested together and showed a reduction in drag of about 40 newtons, roughly 2.4 percent, along with an improvement in net downforce of about 534 newtons in a transient model with 30 million cells. Those numbers matter because they confirm that these parts do more than change the look. They deliver measurable gains that translate to steadier highway tracking, calmer behavior in crosswinds, and a more confident feel through long sweepers.

How the System Works Together

Think of the kit as a chain of small, smart improvements that add up. The Front Splitter reduces the amount of high pressure air entering under the car and adds front end grip. The Front Canard Set guides air around the bumper corners and supports localized front downforce while preserving the factory air curtains. The Rear Diffuser Extension lengthens the working surface and adds two central strakes to keep underbody flow organized for better pressure recovery and reduced drag. The Rear Fins help the side flow stay attached a little longer before it enters the wake, which calms turbulence and supports the diffuser. The Efficiency Trunk Spoiler manages how air leaves the decklid by delaying separation and raising pressure over the surface, trimming drag and improving stability. Carbon Mirror Covers tidy flow around the mirrors while completing the look.

Component Highlights

Front Splitter

Replaces the factory lower trim with an element that extends forward to increase the pressure difference between upper and lower surfaces. This adds front downforce, reduces lift, and steadies the car at speed. It attaches using ten factory style snap fit points for a secure, rattle free install that can be reversed in minutes.

Front Canard Set

Snap fits beside the front air inlets. The raised outer edge acts as an aero fence that resists spillover, guiding air upward and outward for localized front downforce. The shape respects the factory airflow paths, including the front air curtains, and frames the intakes with a clean, assertive look.

Rear Diffuser Extension

Lengthens and subtly enlarges the factory diffuser and adds two central strakes. Extending the exit helps the airflow expand more smoothly into the wake for better pressure recovery, adds rear downforce in the area of lower pressure, and delays separation to trim drag.

Rear Fins

Run along the outer rear quarters to guide side flow so it stays attached a little longer before it enters the wake. Cleaner side flow reduces turbulence and supports the diffuser, contributing to a calmer, more efficient rear wake.

Efficiency Trunk Spoiler

Extends the rear profile to create a subtle long tail effect. By delaying separation and raising pressure over the decklid, it helps the air leave more cleanly for lower drag and a more planted feel at speed. Developed through 143 CFD simulations to deliver real gains with a restrained, factory plus appearance.

Carbon Mirror Covers

Full wrap covers with subtle inner vortex guides that clean up flow around the mirrors while adding a refined carbon finish.

Installation and Reversibility

All parts use factory mounting locations or factory style engagement, which means no cutting and no drilling. Installation is straightforward and tool light, and returning the car to stock takes only minutes.

Materials and Finish

Components use exterior grade construction for strength, impact resistance, and stability in real weather.

Trim Specific Fitment

Model Y Performance Trim Notes

On the Performance trim, the Rear Diffuser Extension, Rear Fins, and Efficiency Trunk Spoiler are designed to work as a team. In development testing, the Diffuser Extension plus Efficiency Spoiler helped the car slip through the air more easily and feel more planted, cutting drag by about 40 newtons, around 2.4 percent, and increasing overall downforce by about 534 newtons in a 30 million cell transient CFD model. Adding the Rear Fins helps the air stay attached longer along the sides, which supports pressure recovery at the rear and lets the diffuser and spoiler work more efficiently. On the road, that means steadier highway tracking and a more confident feel through fast sweepers.

Everyday Benefits You Can Feel

You will notice the difference in familiar situations. The car tracks a little truer in crosswinds, feels calmer during quick lane changes, and settles into long highway curves with more confidence. The best part is how subtle the improvements feel. The car remains quiet and easy to live with, yet the aero work reduces effort through the air and builds a more planted stance that inspires confidence.
