Bolt-In 4 Point Harness Bar System

This product has been discontinued and is no longer available.

-

This bolt-in bolt-out harness bar will have your Model 3 daily driver race track ready in no time! Cutting edge engineering utilizing 3D scanning and CAD engineering enables this to fit perfectly in the Model 3. The design allows the driver seat to go all the way back for taller drivers and also allows ample driver seat recline. The factory interior can remain intact for a factory finished “RS” look (we daily drive with one in ours). After track days to regain full rear seat usage the bars can be removed in under 10 minutes by one person with basic tools and leaves trace of install. The design stores flat and takes up minimal floor space in the garage between track days.

This bolt-in bolt-out harness bar will have your Model 3 daily driver race track ready in no time! Cutting edge engineering utilizing 3D scanning and CAD engineering enables this to fit perfectly in the Model 3. The design allows the driver seat to go all the way back for taller drivers and also allows ample driver seat recline.

After track days to regain full rear seat usage the bars can be removed in under 10 minutes by one person with basic tools and leaves trace of install. The design stores flat and takes up minimal floor space in the garage between track days.

Specifications:

  • Engineering by race chassis engineers using cutting edge 3D scanning and precision CAD development
  • Allows retention of rear seats, headliner and fits precisely without rubbing or obstructions
  • Provides a proper structure and orientation for racing harness use while also providing supplemental roll over protection.
  • Functional high strength construction utilizing machined billet components and Drawn Over mandrel (DOM) racing roll cage steel tubing.
  • Zero cutting to factory plastic or leather interior panels is needed.
  • When removed after track days there is no visible trace of installation.
  • Rear view visibility is retained.
  • After initial installation, the subsequent bolt-in and bolt-out process takes one person under 10 minutes ensuring a simple and speedy transition from daily driver to track warrior. The initial installation takes 3-4 hours.
  • High-quality powder coat finish. The satin black finish is standard, all custom colors are available for an additional cost.

Pairing Recommendations:

  • We recommend our Willans x Unplugged Performance FIA racing harnesses for use with this roll bar
  • We also recommend a proper racing seat with a harness pass-through design. The Unplugged Performance racing bucket seat set is a perfect pairing.

      After using the fascia for over two years, this feels like a must-have Tesla upgrade. The stock Model 3 just doesn’t look the same anymore. I rate 4/5 stars since epoxy would be better than double-sided tape to secure the ultrasonic sensors.

      Looks great, perfect fitment. SUPER FAST SHIPPING!!
      Frank F. July 19, 2025
      I got the titanium finish and it looks sharp! very HIGH QUALITY! very happy with it!
      KEVIN M. October 09, 2022
      Beefy design, necessarily. Need the toe arms in conjunction with rear camber arms to dial in toe at the same time, otherwise toe will be out of spec when adding negative rear camber.
      Shimmy October 23, 2024
      One of my favorite upgrades to the Model 3, allows for fine-tuning of the entire suspension system to balance the car out. Each notch makes a noticeable difference, so certainly flexibility with the settings. I started with Medium/Medium settings and tuned them according to the car's handling.
      Shimmy October 23, 2024
      The shop we had these installed was a 1.5 hour highway drive away so the trip home was a great test to see if we liked them (we live in NC). It was immediately noticeable that the ride of our 2021 Y was softer and bumps were not as hard. We had the shop set our coilovers to setting number "3" and...

      These brakes have been a game changer for the Plaid. It's a bulky 5000lb 1000hp monster and needs brakes that fit the bill. Unfortunately, the stock setup left a lot to be desired especially when climbing towards the higher speeds. At that point, the brake application felt more like a suggestion and...
      Daniel B. September 24, 2022
      I opted to get the race spec coilovers since I track the car. I’m very pleased with the performance of the coilovers. Not to mention the ride height is exactly what I was looking for. Thanks to the Unplugged team for their willingness to assist and answer my questions. They are very...

      Been waiting for this part from UP since purchasing my coilovers almost 2 years ago. This part is completely much more superior than the OEM part and steering feel is much more accurate and responsive.
      jdl21292 April 10, 2023
      Been waiting for this part from UP since purchasing my coilovers almost 2 years ago and just perfect timing that old links are completely shot and this totally changed the overall feel of the car and reduced tension. Customer service is excellent and will be doing next upgrades with UP
      jdl21292 April 10, 2023
      Went with the burnt titanium, simply looks gorgeous with the finish.
      Megatron November 19, 2025
      Got these coil overs installed on my model 3 performance, and wow what a difference. Not only do they outperform the stock suspension in acceleration and cornering, but they also just ride so much smoother. Highly recommend!
      Frank August 09, 2023
      Got these with my order of Moderate Springs and Street/Track Sway-bars and they helped reduced the offset tension of lowering the car. Great product and thank you Blake (from customer service) for answering my questions. Unplugged has been a great company to order from, top notch for sure.

      Dramatic improvement over stock brakes! Can’t imagine roll racing or drag racing without them
      patch2u17 October 20, 2022
      I'm currently putting together my custom UP INVINCIBLE® kit from Unplugged Performance with the help of Frank, and the transformation is insane. The lineup includes the HD Front Bumper with the optional 11-inch LED light bar that absolutely lights up the night, the bulletproof Heavy Duty Rear...
      CyberRiri December 04, 2025
      Amazing! Bought these along with the Unplugged Performance Competition Track Brake Pads and the results were incredible. Took my 2022 Model 3 Performance to Tesla Corsa with these installed and the difference was instantly noticeable. No more mushy feel when the temps got high. Brakes felt solid....
      Tesla S. October 19, 2022
      Beautiful wheels. These have the most style. The black matches perfectly with the blue. To complete the look, add the super light titanium lug nuts and the carbon ceramic front big brake kit, as shown in the picture.
      raviprabhakar October 03, 2022
      I purchased the camber and toe arm set my Tesla Model X Plaid. The primary purpose of buying these arms was to reduce the inner tire wear. These arms are well engineered, beautifully crafted and built solid. I highly recommend these products made by Unplugged Performance. The craftsmanship of the...

      I recently purchased the UP-03 Race Spec Wheels for my Tesla Model 3 from Unplugged Performance. Although the wheels look great and undoubtedly enhance the driving experience, I encountered a few issues during the process. Firstly, I was not informed that I would need spacers for the UP validated...
      David S. April 19, 2023
      This has been one of the best upgrades Ive made to my Plaid. Really makes the car much more stable at high speed, corners better, and there is no loss in comfort even in the stiffest setting.. Very happy with this bar!
