      My only complaint is the FSD doesn't work with this on, which renders it useless to me.
      Taxxman December 10, 2025
      Extremely well built and engineered. Best on the market.
      Cordell November 24, 2025
      On the track or not these sway bars make your car feel solid on turns. Immediately I noticed improved corner turns which is great! Highly recommend!
      jesus.ruiz.2389 February 02, 2023
      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...

      Bryan L. December 05, 2025
      This bumper is awesome for my Cybertruck! It’s built tough with A36 steel, looks killer with the black powder coat, and the optional 11-inch LED lights are super bright. It’s great for off-roading with a better approach angle and hi-lift jack points. Installation was easy with the video guide,...

      These bearings were installed for me by a shop that unplugged put me in touch with. Their service was excellent. The bearings were able to be installed with zero use of heat, unlike bearing kits for other cards and potentially from other brands. The road feel and confidence in the back end is...
      Steven S. October 20, 2022
      I was tired of replacing my rear tires all the time, between the power and weight of the Model Y P, this camber finally allowed me to dial in my alignment for tire wear and better traction. Will pay for itself with tire savings.
      Jorge (. August 23, 2022
      Purchased a 19 x 9.5 UP-03 wheels. They look awesome, feel lighter when you're steering, and I'm able to gain 1-2 % of range when driving around town. Shahar helped me through the purchasing process and set me up with a relatively painless cross-border shipping arrangement. Keep up the good work!
      Lamown September 16, 2025
      These nuts are awesome! So much lighter than the OEM and they look so much cooler. Reduces unsprung weight while looking cooler which is a win-win. I went with the burnt titanium finish which looks incredible and really adds some color to your wheels in a subtle way. Highly recommend.

      We are loving our new UP Luxury Coilovers on our 2021 Model Y! The improvement is noticeable at level 8, the car handles bumps much more smoothly, and the handling seems to have improved as well. I worked primarily with Kirk and he was great. Very approachable and easy to talk to. He talked...
      ejoshuahill June 09, 2023
      Installed front big brake kit and noticed extreme improvement over stock model x plaid brakes. Later installed the rear carbon ceramic rotors and pads and noticed an appreciable increase in braking power and am now quite comfortable braking from speeds in the 160mph range and that was not the case...
      patch2u17 May 09, 2023
      These springs are a game changer. Completely revamped my M3 from a performance and cosmetic standpoint. Soft/comfortable during your daily commute and stiff/precise during "spirited" driving. Cabin noise is also drastically reduced. Cannot recommend this product enough. Call and ask for Kirk Nason,...
      Jordan C. June 09, 2023
      These coils-overs provided my vehicle with the necessary lift and dampening required to conquer truck trails on the way isolated camp sites (San Bernardino Forest Yellow Post). Love this product. Another great feature is the ability to access the dampening adjustments with little effort. (Top frunk...
      josephschneider77 November 04, 2022
      I placed an order for the Satin Asteroid Graphite wheels with Michelin Pilot Sport Tires after I had the Luxury Coilovers installed on my Model Y. Within 2 weeks I was back in Hawthorne to have them mounted, balanced and aligned. The style contrasts perfectly with the Satin PPF wrap on my car. ...

      Perfect fitment. Look great after 2+ years. Wish mine came with end links :(
      valstewart September 29, 2022
      I purchased the entire suspension front and rear adjustable, and fixed spherical bushing arm sets, along with the rear sway bar for my 2022 Tesla Model S. After the complete UP installation, and spec alignment, the car is a different Monster. Not only it is firm and stable at high speeds, but...
      crisonesurf April 21, 2025
      Got these with my order of Moderate Springs and Street/Track Sway-bars and they do what they are intended to do. Got my alignment darn near within spec which will help with tire wear. I haven't had them for long so I can't comment on durability but they sure are built sturdy as hell. If you are...
      850arrrsaylikepirate December 19, 2022
      Great add on for your Tesla to really dial in the alignment! Great time to do it is when you’re lowering your car already or getting an alignment anyways. Improving tire wear is very important for me as I drive a lot and been getting more miles/set than ever before. Highly recommend!
