Product Details

The performance and aerodynamics of a car are often best visible at the rear and this Rear Under Spoiler/Diffuser system lets people know that your Model S is a serious performance car.

The design is a mix of functional aggressiveness and it takes Tesla’s factory rear diffuser design to a new level. The subtle elongation of the rear diffuser enhances the air diffuser effect Tesla has already designed into the car. All five of Tesla’s functional underbody diffuser fins are kept intact and well integrated into the new design.

Available without the fin panel for a subtler look, or choose the fin panel option for a more aggressive aesthetic.

This part is offered in the following finishes: unpainted, premium factory color paint, or in beautiful carbon fiber. The Unplugged Performance Rear Under Spoiler and Diffuser System is designed and produced to the highest quality levels in Hawthorne, California.

Starting September 2015: All rear under spoiler/diffuser systems in either unpainted or painted variations are produced in a Tesla factory style of impact resistant urethane. This production method allows significant durability as the material rebounds to the factory shape after experiencing an impact. The carbon fiber option remains as carbon fiber for those looking for supercar grade lightweight construction.

Compatible with all Model S variants produced before Spring 2016.

Tesla’s production of the Model S utilizes many ongoing minor adjustments which occur often without public announcement and without following a traditional model year cycle. As a result of our experience, we produce multiple variations of our parts to ensure a best fitment match Tesla’s many publically undocumented variations. For our research and development to benefit your order please provide us with the production month/year, trim specs, color, and VIN when you submit your order.

      Frequently Asked Questions - F.A.Q.
      Everything you need to know about this product before you buy.

      What does the Unplugged Performance product warranty cover?

      Unplugged Performance offers a comprehensive warranty on all parts and installations performed by our certified technicians. Warranty coverage applies to defects in materials and workmanship on items including lowering springs, coilovers, big brake kits, brake pads, stainless steel brake lines, shocks, and more. Should any covered part fail under normal use or display premature wear, we will repair or replace it at no additional cost—assuming the component was installed by us or at one of our authorized partners.

      This warranty is valid for 2 years or 24,000 miles, whichever comes first, excluding consumable products like brake pads, rotors, and tires, starting from the installation date. 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.

      Will installing Unplugged Performance parts void my Tesla warranty?

      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. 

      What are the shipping options and times?

      Unplugged Performance processes orders quickly, typically within 1–2 business days after placement. For U.S. customers, orders under $50 usually ship via FedEx SmartPost with an estimated delivery time of 2–7 business days. Larger items like body kits or bumpers may ship via freight carriers with curbside delivery; customers will be contacted to schedule a delivery window. International shipping is available to most countries, with shipping costs calculated at checkout. Delivery times abroad vary, generally ranging from 5 to 16 business days depending on destination. Import duties or taxes are the customer’s responsibility. To ensure a smooth shipping experience, provide accurate contact information during checkout. For specific questions or shipping quotes, Unplugged Performance’s support team is available to assist.

      Sports Dynamic Air Suspension Upgrade (Lowering) Kit for Tesla Model S (2012-2020)
      I tried the sports dynamic kit because I wanted a lower center of gravity for autocross. That it has a stock/sports spec that can be relatively easily modified was a draw, in addition to the idea that these are a fixed bracket that sets in place. The installation was indeed quite straight forwards,...
