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.

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.

      These springs were the first real mod I’d ever done to my Tesla and I’m so happy with the way they turned out. They really complete the look on my model 3. And I was surprised to find you don’t sacrifice anything in terms of ride comfort by adding them. The only problem is that now that I’ve...

      Worth every penny. The iron BFB is one of my favorite things I’ve done to my car so far. Brakes are one of the most important things on a car and I notice such an improvement with these over stock brakes. On track I am able to brake much later into corners and the brakes have basically zero fade...

      My wife drives a Model Y as her daily driver and for a commuter car the model Y suspension can be very harsh. Purchased the luxury coilovers and sway bars to help with this. Only 1 mechanic in North Carolina was certified to do it that was in the unplugged performance network and I had problems...

      Not a fan of the OEM rear look of the Model 3. This got me looking back at my car every chance I get! Better rear downforce as well. Feels much more confident around turns at high speeds.
      Andrew P. September 07, 2022
      These brakes perform great and I should have upgraded to these a long time ago. Pedal travel with with the included brake lines are much improved as well.
      Quan February 01, 2023
      I purchased the camber and toe arm set for 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...

      Had a great experience with Andrew from Unplugged, I sent an email request for more information regarding the camber kit and Andrew called me back quickly and discussed the product and how it will improve the tire wear on my model X. He kept in regular communication from the time of order to...

      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
      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
      Best modification I ever did to the Tesla combined it with H&R lowering springs pears very well to fix the suspension quality that is given in stock. Easy Job doesn’t take more than 2 hours.
      Pat M. October 09, 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
      WIFE APPROVED!!! I have a 2018 Model 3 LR AWD with the stock 18" wheels. I've always felt that the ride was a bit stiff and jittery with the stock suspension. Looking around for a solution, I came across coil-over kits which were expensive and I really didn't think I would need the adjustability...

      Dominic Marcu - Racing Driver perfect! with their help I can have the desired setup for the competition car.
      Dominic M. April 12, 2023
      I went with the 30mm spacers just to give the Cybertruck a slightly wider stance. These are very well-built. I have put almost 2,000 miles on the truck since installing the spacers and couldn't be happier. The driving dynamic did not change noticeably and I have not noticed a significant reduction...
      Josh H. December 09, 2025
      Same as the fascia, this feels like a must-have Tesla upgrade. The stock Model 3 just doesn’t look the same anymore. I love the dry carbon material and would highly recommend. I wish the diffuser fins came standard, even with a higher cost. With some DIY, you can make the air ducts in the bumper...
      David S. November 06, 2022
      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
      I always hated how my Model Y would sway side to side at high speed on the highway when the road conditions were poor, even with the coil overs I wanted a little more stiffness and this fixed the problem, now it feels more like a Porsche/BMW M.
      Jorge (. August 23, 2022
      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 would recommend epoxy over double-sided tape to secure the ultrasonic sensors for a longer-lasting, flush fitment.
