Tesla Model 3 Performance (2024+) Carbon Fiber Rear Diffuser Trim

It is a carbon fiber cover that fits over the factory rear diffuser and lower bumper trim to bring a hypercar-style carbon look to the back of the car. On the 2024+ Model 3 Performance it blends into the body contours and ties the rear together when you run other UP carbon pieces. This particular part is styling-focused: it dresses the existing diffuser rather than adding a new aero surface.

It fits the 2024+ Tesla Model 3 Performance only. It is shaped to sit over that trim’s factory diffuser, so it is not designed for the Long Range or RWD Highland rear bumper. If you own a non-Performance 2024+ Model 3 and want rear carbon, the rear spats fit all trims and are the better match for your car.

Inside the box are one diffuser trim and one mounting kit. The trim is made from 100% prepreg carbon fiber and comes in Matte or Gloss base coat. As with our other carbon, the base coat shows the weave and is meant to be clear coated or protected at a local shop for the long haul. One piece, sized to the Performance diffuser.

Yes. It fits right over the factory Model 3 Performance diffuser trim with no drilling, which makes it friendly for any DIYer, and it peels off later without evidence it was there. That clean removal is handy for lease returns. Local to Los Angeles and would rather we handle it? Our Hawthorne team can install it and share pricing and scheduling.

This trim is primarily an appearance upgrade. It fits over the stock diffuser to deliver a cohesive carbon look and does not claim its own downforce number. If your goal is measured rear aero gains, the Carbon Refresh Aero Kit pairs a diffuser extension with an efficiency spoiler and shows CFD downforce figures. Buy the trim for the finish, not for a lap-time change.

It is designed to pair with the UP Rear Spats, rear wing, side skirts, and front aero for a matched carbon build. Run together, the pieces follow the factory lines so the rear looks intentional rather than patched together. The trim handles the center of the bumper while the spats take the lower corners.

The diffuser trim changes the look at the lower center of the bumper with no real aero claim. A rear wing like the Ascension-R sits up on the trunk and generates meaningful downforce for stability at speed. If you want visual polish, the trim does it affordably. If you want the car to feel planted on track, the wing is where the money goes.

It has been listed as preorder with new orders estimated for the back half of 2025, so confirm the live ship window at checkout since dates move as production catches up. Placing your order now reserves your spot in line. If you are timing it against an install appointment, our team can give you the current estimate directly.

Adding this trim does not void your Tesla warranty by itself. The Magnuson-Moss Warranty Act requires Tesla to show a specific failure was caused by the part, and a cover that sits over the factory diffuser does not touch a warrantable system. It installs without drilling and lifts off cleanly, so reverting to stock before a service visit takes minutes.

This trim is a single molded cover, and under the visible weave it carries a dry-carbon-kevlar backing cured by prepreg-autoclave, which beats wet layup on strength for the weight. The original owner gets 5 years on fitment and function. Its base-coat face is meant for clear coat or a wrap at a shop, so UV discoloration or chips on bare carbon are not covered structurally.

Coverage extends to labor for warranty repairs when performed by Unplugged Performance or an authorized installer. It does not cover damage resulting from misuse, accidents, off‑road use, improper installation not done by us, or modifications that aren’t factory-approved.

To file a warranty claim, simply contact our service team. We’ll guide you through inspection, shipping (if needed), and repair or replacement logistics. transparencia and top-tier support are what you can expect from Unplugged.

Installing aftermarket parts does not automatically void your Tesla warranty. Under the Magnusson-Moss Warranty Act (www.sema.org/sema-enews/2011/01/ftc-validates-right-to-install-aftermarket-parts), a manufacturer cannot void your warranty simply because you installed aftermarket parts. Tesla must prove that the aftermarket part caused the specific failure in question to deny a warranty claim. UP recommends retaining all factory parts to allow reverting to stock if needed.
