We strive for perfection with everything we do. We pioneered the world’s first adjustable upper control arms for the Model 3 back in late 2017. Since then we’ve gone through multiple versions, many of which we kept for internal development and never saw public release. Over the years we’ve grown and have had the pleasure of supporting thousands of streetcars as well as setting racing records around the world. Our experience has led us to what we’ve internally called our version 4 front upper control arm. In simple terms, we feel it is the Ultimate. We’ve set records with the fastest Model 3 and Model Y on early prototypes of these and we’re pleased to release them to our clients. Read on to see why we call these the ultimate…

*Updated for summer 2021 onward to enable extreme clearance to ensure no contact with chassis in the most severe use cases. As utilized in Germany on the full TUV road legal UP development Model 3 Performance which is kept at the Nurburgring & tested for over 15,000km of hard Nurburgring track use and counting!

Patent Pending Camber Quick Change Pill
We drive our race cars to the track on Autopilot, set lap records, and drive home. This is the preferred way to experience the amazing duality of a Tesla being the perfect daily and the perfect track weapon. We wanted a solution that was the ultimate in precision for a camber quick change. We came up with a two setting quick-change pill design that can be swapped at the track in 5 minutes using just an Allen wrench and a floor jack. You’ll notice from a top view the clear labeling of Street or Track camber setting of the ball joint. The beauty of this design (aside from the speed of swapping) is that it is precision engineered and machined to allow the most accurately consistent retention of alignment setting that is not achievable as precisely any other way. We all spend a lot of time and money on getting finely tuned alignment settings for our cars. This method keeps the alignment precise between quick camber swaps between street and track. You’ll never need to worry about alignments remaining precisely where you set them, even after much quick camber changes. Simply enjoy two degrees of additional negative camber at the track and when you swap it back you’ll be spot on to your original street alignment.

No Expense Spared – Asymmetrical Billet Design With Camber, Caster, and Toe Adjustment
It isn’t cheap to install parts, get alignment, and race. We figured why cut corners on budget when a few hundred dollars more can make the difference in performance, let’s just build the best product money can buy. Sure enough, these were not cheap to make. Each monoblock aluminum arm encases the ball joint in a massively rigid asymmetrical design. You’ll notice laser etching denoting LH and RH sides reflecting this. Each side has easy to access turnbuckles and bottom access adjustment points for alignment and provides full control of camber, caster, and toe for the ultimate in alignment options. The shape is precisely sculpted in CAD to optimize suspension travel and retains clearance on full compression.

Negative Camber – Sure How Much?
More than you can afford pal. Seriously though, when we tested on our race car we maxed out at 5.8 degrees of negative camber on our race setting (3.8 degrees on street pill setting). It is safe to say that there is more camber adjustment possible than anyone would ever need. On our race cars we find the fastest settings on race slicks require -4.0 degrees of front camber which these do with ease. Want to lift your car and go overlanding? No problem, these can go positive camber as well to offset for increased height. This design allows for the maximum in flexibility of adjustable camber range. Please note that actual max/min camber depends on variables such as vehicle ride height and type of spring/shock combination.

Silent and Low Vibration OEM Type Sealed Spherical Bearing Design
We’ve set multiple racing records with these but you can enjoy them for your daily commute in blissful Autopilot enabled meditative silence as well. We guarantee it, along with all of our suspension products.

Quality You Can See
We spend a lot on materials and we like to show them off in a hi-tech way. We use a rugged and corrosion-resistant Cerakote clear coating to encapsulate and show off the precisely CNC machined and laser etched aircraft grade 6061-T6 billet Aluminum.

Wheel Speed Sensor Mounting
Although not shown in the initial photos, we include in the design an integrated attachment point to securely attach the wheel speed sensor line.

    As part of my purchase of the Luxury Coilover Suspension for my Model Y, I included both the Front Upper Control Arms and Rear Camber Arms, to mitigate any issues with uneven tire wear. When I purchased the UP / BBS Flugplatz wheels with tires, I was relieved that the additional 2 pieces were installed. In my opinion, FUCA and rear camber are required in order to reap the maximum benefit of the upgraded suspension. It creates a smoother ride than stock, with the ability to customize based on your preference.

    I got the FUCAs installed on my 2018 Performance Model 3 and wished I hadn’t waited so long to do it! Now I can do proper alignments with camber on the front, not possible to do with the stock control arms. You can also put custom wheel sizes with super wide tires on the front without worrying about rubbing. I just had it on the track, and the alignment and wider 255/35/20 tires were incredibly helpful. Together with the other mods, I was able to achieve save 4 seconds on my personal best time at Buttonwillow, and the car still has more to give. The car actually rides like a new car now, and in my opinion, better than when brand new. Amazing!

Shout out to Andrew at Unplugged Performance! Customer service is excellent. Great communication with everything. Knowledgeable about all products. Will do more business with UP.
I have my model 3 performance and love it and now after adding these coil overs, can’t comprehend why these aren’t stock for tesla. These coil overs are amazing automagically felt like the car was on a cloud, handles great, and very smooth. Noise is reduced and can not believe I took this long...
I've covered innovation in the vehicle space for a long time. Mercedes Benz gave me its first ride in its first autonomous vehicle. BMW drove me around SXSW in the first i3 electric all week long. I wrote four books on technology, predicting with each decade-long trends. I have the first video on...
I wanted to wait a few weeks before leaving my review to really see if there was a significant difference and it is a significantly better ride. I commute 70 miles a day on a fairly rough socal highway and the change is noticeable. Yes, you’re still going to feel the bumps but they are not as...
Had the bars installed with the end links on my M3P, at the same time lowered with performance springs and got new tires. No regrets. The car rides flat af. I look forward to round-abouts now. Big ups to UP.
My 2019 Performance Model 3 is great, but with the heavy weight of this EV the cornering at high speeds was disappointing. I recently added these Dual Rate Lowering Springs to the UP Sway Bars, and the handling is definitely getting better! The initial spring rate makes the bumps less jarring with...
These are exactly what I was expecting. I waited over a year for them. Pandemic backorders and all. It took me about 6 hours to install with help from a friend. The fronts were the worst part. You have to have the spring compressors mounted just right and really compress them a lot to assemble the...
These dual rate springs were the most noticeable and effective upgrade I've made to my Model Y. Much better handling and comfort compared to the stock standard rate springs.
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...
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.
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!
LOVE my new UP-03 wheels. Super light, super strong and they look so good. Super high quality finish on the wheels too, worth every penny. Have had the wheels for just a few days and have gotten tons of compliments on the road and at the track. These are the best wheels you can buy for your Tesla,...
Received my suspension for my Y 2022 long range what a difference. Set it for 8 on the adjustment rides totally different what a great job took it to a friend of mine Frank Reyes to install Desert car medics said the product was very well made installed it in about 5 and 1/2 hours. Driving it for a...
I purchased these as set with my coil overs and these are definite must to install. These bushing add great handling to your steering. Steering is more accurate and responds well to the drivers needs. Highly recommend!
Paint match was perfect. Fit is perfect. It’s exactly what I was looking for, exceeded expectations.
Moto Miwa definitely made the right recommendation for the Moderate Lowering springs for my Model 3 Performance. They gave it the perfect balance between drop and functionality - good ride quality and no scraping. Also, in another conversation regarding tire wear, Moto suggested I purchase the...
Purchased these with the luxury coilovers but kept things at stock ride height. So far, everything is great!
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...
Oh, wow; it is insane that one bar can dramatically alter the dynamics of the car. It is so much more planted and stable during those freeway maneuvers, which was the primary reason I bought the bar. The car is just solid at all speeds. Really solid. What is shocking is that the comfort levels seem...
If love carbon fiber like I do then this is a must. Nothing compares to UP carbon coaster. The weaves are super clean, very sturdy, looks great. I couldn’t help myself and got this to add to my carbon collection.
