quick product info sheet

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.

GT Rear Strut Tower Brace Includes

  • (1) Cross Bar
  • (4) Mounting Brackets
  • (8) Mounting Bracket bolts
  • (2) Lower chassis mount bolts
  • (2) Upper chassis mount nuts

      Purchased these to dial in my rear alignment, went through so many rear tires glad to be back into spec. I had a tire blow out on the freeway with my family because I didn't notice the inside of the tire had worn down so much in just 4k miles! These rear-toe arms would have avoided that ordeal.
