Tesla Model X / Model X Plaid (2021+) Billet Adjustable Rear Camber Arm Set
$1,516.00
The development of advanced Model X suspension parts and the racing program kicked off June 2021 with our race car Dark Helmet as we set out to develop the ultimate performance handling Model S. The results have followed as we brought home to the Tesla community a Pikes Peak class victory and multiple production-based EV lap records with our development race car. As a result, we were able to develop an entire range of suspension components that can be purchased individually or as a comprehensive lineup upgrade, all catering to improved driving dynamics & performance, both on and off the track.

Tesla Model X / Model X Plaid (2021+) Billet Adjustable Rear Camber Arm Set
The development of advanced Model X suspension parts and the racing program kicked off June 2021 with our race car Dark Helmet as we set out to develop the ultimate performance handling Model X. The results have followed as we brought home to the Tesla community a Pikes Peak class victory and multiple production-based EV lap records with our development race car. As a result, we were able to develop an entire range of suspension components that can be purchased individually or as a comprehensive lineup upgrade, all catering to improved driving dynamics & performance, both on and off the track.
All of our suspension development begins with precision 3D scanning of the car’s suspension to develop a working digital model, then followed by real-world racing and street use internally on our company vehicles before rolling out to the public. Our history, race results, and industry-leading warranty provide peace of mind that these are the best money can buy. In turn, you will be able to tap into the race-derived performance parts, developed specifically for the grueling conditions of the likes of Pikes Peak International Hillclimb or the highly-demanding tracks like the Laguna Seca, all for the Tesla Model X, a luxury seven-seater family hauler that will now be able to compete with the likes of the BMW X5 M or the Mercedes-Benz GLE 63 AMG both on and off the track.
Billet Adjustable Rear Camber Arm Set
The Model S Plaid + LR Billet Adjustable Rear Camber Arm Set for 2021+ Tesla Model X variants, has been developed on our Pikes Peak Class-Winning “Dark Helmet” race car. The multi-link rear suspension on the new Model X presents a large engineering challenge to solve to allow both maximum adjustment of rear camber as well as proper usability for the technician performing the alignment. In going through a myriad of suspension settings for Pikes Peak as well as record laps at Laguna Seca and Buttonwillow we ended up doing alignments over and over. These camber arms provide maximum alignment flexibility and durability with sealed spherical bushings and CNC-milled billet aluminum construction, coupled with high-strength stainless steel adjustment mechanisms.
For racing use, this is a popular upgrade to ensure maximum performance on the track. For street use, this is a popular upgrade that allows you to adjust the rear camber to neutralize uneven tire wear, especially when lowering the vehicle or driving at highway speeds.
- CNC-milled 6061 aluminum for maximum strength while saving weight
- FEA-simulation optimized to ensure superior static, dynamic, and fatigue strength
- Sealed spherical bushings for unmatched precision and durability with silent operation
- Largest possible camber range adjustment from +1 to -4.5 degrees camber
- Ensure maximum tire patch contact on the race track
- Deliver optimal tire wear characteristics on the street

How much camber adjustment do these arms give?
The set offers the largest possible range on this platform, from +1 to -4.5 degrees of camber. That span covers everything from a neutral street alignment that protects tire life to an aggressive negative setting for maximum grip on track. Few adjustable arms open up that much room. It means one set of arms serves both the daily driver and the track-day crowd.
Do these fit the Model X Plaid, and what do they cost?
They fit the 2021+ Model X and Model X Plaid, which share the new multi-link rear suspension. The set is priced at $1,610.75, down from $1,895.00, under SKU UP-MSMX2-103-4.1, and ships the next business day. Owners dialing in a full rear alignment usually add the matching rear toe arms alongside them.
What are these camber arms built from?
CNC-milled billet 6061 aluminum for the arm bodies, sealed spherical bushings at the pivots, and high-strength stainless steel adjustment mechanisms. That combination gives you strength alongside precise, silent movement from an adjuster that holds its setting. The design is FEA-optimized for static and long-term fatigue strength. It is built to survive the same abuse we put it through on the race car.
Which race car were these developed on?
Our ‘Dark Helmet’ Model X Plaid race car, which took a Pikes Peak class victory and set multiple production-based EV lap records. Chasing setups for Pikes Peak and record laps at Laguna Seca and Buttonwillow meant doing alignment after alignment, which is exactly what shaped these arms for both maximum adjustment and real usability at the rack. That development transfers straight to your car.
Does correcting rear camber actually improve grip on track?
It does. Setting negative camber keeps more of the tire flat on the road when the car leans in a corner, which enlarges the contact patch right when you need it. That translates to more mechanical grip through the turn. On a heavy Model X pushed hard, dialing camber to suit the tire is one of the higher-value rear suspension changes you can make.
