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.

      Purchased the sway bar for my plaid about a year ago after hearing good things about it on the Tesla forum. Unfortunately, I got super busy and I didn’t get a chance to install it until recently. Very happy with the purchase and there’s a very noticeable improvement in handling. The car also...

      Real cool suspensions the car drives smooth and quite. Made a real difference to the drivability and now I really enjoy driving the car. Absolutely recommend it if your factory shocks have failed. Mine failed in 5 years.
      kerbad October 01, 2024
      I have both the rear camber arms and the rear toe arms together making the rear alignment easy and quick to change. I adjust back and forth between street alignment for daily commuting and autocross race alignment for race day. These are easy to use and the settings are very repeatable. Customer...

      My only complaint is the FSD doesn't work with this on, which renders it useless to me.
      Taxxman December 10, 2025
      Product is top notch when I installed them it was like switching from a 1 piston sliding caliper to a bbk. Also cold performance and noise are really good
      Christos K. November 04, 2022
      Bought the shock and it works great. Definitely recommend for Model Y owners on limited budget.
      Dennis Y. January 20, 2024
      I purchased this Unplugged Performance Ascension-R Carbon Fiber Rear Wing for my Model 3 and I'm very happy with it. It not only looks good but it's adjustable and increase downforce as well. I will placing another order soon for my Model Y. Highly recommended! Link:...
      f1dinesh August 07, 2023
      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.
      Jorge (. August 23, 2022
      Sway bars changed behavior of car. It was straight forward to install. Thanks to the Unplugged team for providing guidance on the correct way to setup sway bar with the adjustable end links. Very happy with product!
      juanlop687 May 09, 2023
      Perfect fitment. Look great after 2+ years. Wish mine came with end links :(
      valstewart September 29, 2022
      Finally!!!! Been waiting on UP to both have a decent Black Friday sale and to have this item on it and whatdoyaknow…..HALF OFF! I wish it was all gray everywhere, but I’ll do the touch up myself and get it 100% how I need it!!!
      Montage Ø. November 07, 2025
      Love the look of these as they add a more aggressive look for the front. Same subtle style that goes along very well with the front lip for non-performance M3.
      Christian N. December 23, 2025
      I have tracked my m3p twice now at road America and a local track blackhawk farms. The power to pull the car out of corners make it pretty competitive in stock form. The number one complaint was body roll and poor weight transfer into corners. The competition sways eliminated all of those concerns....
      nfsu95 September 22, 2022
      Excellent product! I installed mine as my first step into getting some more performance out of my M3P for Autocross. The front and rear sway bars along with some wider wheels and stickier tires really took my lap times to the next level. I would say, if you drive hard with these sway bars like I...
      sean4528 January 03, 2023
      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
      A must to get with the coil overs installed on my model 3. I’m sold on these and are definitely getting the upper control arms next.
      Frank August 09, 2023
      HIGHLY RECOMMEND THE SPORT PRO COILOVER SUSPENSION KIT. SUCH A GREAT PRODUCT. MUCH BETTER RIDE THAN STOCK. FEELS LIKE I’M DRIVING A SPORTS CAR AND LOOKS AMAZING! ALSO LOVE THAT IM ABLE TO ADJUST HEIGHT AND DAMPING. THANK YOU ANDREW AND UNPLUGGED PERFORMANCE TEAM.
      elizabethbanuelos81 September 17, 2024
      I installed the Unplugged Performance UP INVINCIBLE® HD Rear Bumper with Hardcore Trailer Hitch Receiver on my Tesla Cybertruck, opting for rear rock sliders and LED flood lights, no swing arms. This thing is a beast! Built from tough A36 steel with a sleek black powder coat, it’s perfect for...
      Tim W. September 28, 2025
      I had these on for a few thousand miles before getting coil overs. The car looked and and felt great with and without a full load of passengers. I got the moderate stiffness, and the car was planted. Highly recommend!
      Sof October 18, 2022
      Perfect look and pairing with the high efficiency spoiler and rear diffuser trim on the Model 3 Highland. Shoutout to the Unplugged Performance team for making this happen.
