Tesla Model S / Model S Plaid (2021 – 2026+) GT Rear Strut Tower Brace
$2,295.00
-
The Unplugged Performance Rear Strut Tower Brace for the 2021 – 2026+ Tesla Model S Plaid and Long Range provides increased chassis rigidity, resulting in better in-turn response, tighter driving experience, and even reduced interior squeaks and rattles. The front suspension of the Model S is braced by the firewall and front strut tower bar from the factory; however, the factory setup for the rear of the chassis is absent of any bracing and is free to sway and flex under higher g-force loads when driving spiritedly or racing, or on uneven surfaces. Our Rear Strut Tower Brace solves this issue to eliminate rear chassis flex.
- Improves rigidity for tighter, more predictable handling with less chassis slop, even on the soft standard air suspension.
- Reduces curb-parked chassis flex from nearly 1” to zero flexion. On-track chassis flex reduction is even larger but more challenging to measure.
- Nearly infinite reduction in flex between rear shock towers and 92% improvement in overall rigidity.
- Customers report reduced interior squeaks and rattles in addition to the performance benefits.
- Designed to retain full functionality of the rear parcel shelf and rear seat folding, and has minimal impact on storage capacity.
- Easy 4–bolt quick removal and reinstallation. The center X portion of the bar is designed for easy and quick removal for when full rear seat-down storage is desired.
- Precision-welded mild steel construction with billet machined attachment points and stainless steel hardware.
- CAD developed and FEA tested for strength.
- Utilizes factory mounting points.
- Fully reversible installation with the only modification required being carpet trimming.
- Black powder coating for a durable, scratch-resistant finish.
- Any color and finish is available by request at an additional cost.
- Lifetime warranty & 30-day satisfaction guarantee.
- All necessary hardware is included.

Product Details
Tesla Model S / Model S Plaid (2021 – 2026+) GT Rear Strut Tower Brace
The 2021+ generation of the Tesla Model S looks quite similar to the earlier generations on the outside, but the updated Plaid and Long-Range models are built on an entirely new chassis architecture that relies on the battery pack as a structural element. While being an engineering masterpiece by Tesla that lowers the center of gravity, the impactful result is an ultralight construction that allows for a significant amount of flexion in the upper portion of the chassis. The effect of this flex can be felt from the driver’s seat primarily through sway, slop, and interior noise such as squeaks and rattles caused by the movement occurring in the upper chassis.
This is the issue that the Unplugged Performance Rear Strut Tower Brace solves. By bracing both sides of the rear strut perches together we are effectively removing all flexion that occurs in the chassis from right side to left side, as well as fore, aft and cross-chassis flexion. The benefits of eliminating chassis flexion with the Rear Strut Tower Brace include improved steering turn-in, more predictable handling and less interior squeaks and rattles.
Increasing rigidity by bracing the rear strut perches of a car is common practice in many legendary and highly accredited sports cars and supercars including the Porsche 911 GT RS, Nissan GT-R Nismo, various models of Ferrari and Aston Martin, to name a few. Most of these vehicles have chassis engineered for rigidity and still find evidence of the improved effects of their factory rear strut tower braces. The benefits of our Rear Strut Tower Brace on the Tesla Model S chassis is even more extreme. Driving is believing!
In our development and testing process, we measured chassis flex based on the movement of the rear strut perch relative to the right side with one wheel up on a curb and the other on the ground, both in factory spec, and with our brace installed. In this scenario, the delta is almost a full inch reduction in flexion and that’s with no lateral g-forces applied! The Unplugged Performance Rear Strut Tower Brace takes the Model S’s driving experience from loose and floaty to smooth, solid, and precise.

Will upgrading my brakes void the Tesla warranty?
Tesla’s warranty covers factory-installed parts, but it does not automatically void your warranty if you install aftermarket components like Unplugged Performance brake kits. Under U.S. law (Magnuson-Moss Warranty Act), Tesla must prove that an aftermarket part caused a failure in order to deny warranty coverage. Our parts are engineered to work harmoniously with Tesla OEM Brake systems and can be professionally installed by Unplugged Performance in Hawthorne, CA or by an authorized installer to minimize risk. That said, any damage directly caused by misuse or improper installation may not be covered. We recommend retaining all factory parts so you can revert to stock if needed. Many Tesla owners enjoy peace of mind by using Unplugged Performance products, which are extensively tested and installed by certified professionals. If warranty concerns are top-of-mind, our team can help clarify compatibility and installation best practices to ensure a worry-free experience.
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 Tesla void my warranty if I install aftermarket parts?
A vehicle’s comprehensive warranty as a whole may not be voided due to use of aftermarket parts per the Magnusson-Moss Warranty Act (www.sema.org/sema-enews/2011/01/ftc-validates-right-to-install-aftermarket-parts). However, a manufacturer may require a customer to pay for parts and labor for a repair if there is direct causation between a customer’s alteration and the product or service repair being requested. It is in both manufacturer and customer’s interest to follow logic and reason so that the system of good faith is not abused. If this topic interests you please read the law as well as your warranty documentation. Ultimately we are Tesla owners and enthusiasts, we are not lawyers and cannot provide legal advice.
