S/X Full Advanced Suspension Control

Works on 2021.5-2026 Tesla S and X -- Both Plaid and Long Range AWD

Take full control of your suspension height. Raise or lower the car without aftermarket links, with precise adjustment at each corner down to the millimeter.

Activate a dedicated stance mode to completely slam the car while parked, fully adjustable for the exact look you want (up to -41 mm).

AND new Advanced Suspension Control.  This feature gives you expanded control over suspension behavior, allowing you to tailor both compression and rebound settings to your preferred ride and handling characteristics.  

2021-2025 Tesla Plaid include an Advances Suspension menu that provides some level of manual adjustment.  This menu does not exist on the 2026 Plaid.  

This add on provides a 15 steps of compression and rebound adjustment.  The additional resolution makes it possible to fine-tune the suspension with much greater precision, whether you're prioritizing comfort, stability, or performance.  Note that the compression and rebound are NOT independently adjustable for front/rear -- it is one setting for both.

Your custom Comfort+ and Sport+ profiles replace the factory Comfort and Sport modes. Once configured, you can switch between them directly from the vehicle's touchscreen, with no tablet required.

Comfort+

Comfort+ softens the suspension beyond Tesla's standard Comfort setting, delivering a smoother, more compliant ride. Drivers familiar with the Raven Model S will find the ride quality very similar, with improved absorption of road imperfections and a more relaxed driving experience.

Sport+

Sport+ unlocks independent compression and rebound tuning similar to the controls normally reserved for Track Mode, while allowing you to remain in Sport Mode. The result is a more responsive, performance-focused setup with the ability to dial in suspension behavior to your preference. For drivers who want a firmer, more connected feel, Sport+ takes the factory Sport setting to the next level.  I've run my personal record 1/4 mile in Sport+.

Anti-Squat/Lift
This allows you to stiffen the suspension during instant full throttle or launch control, reducing rear squat and front-end lift.

This requires a 64 bit Windows device to activate and configure.  

You can add a Windows tablet and charger as an option.  This is a rugged touch screen tablet that fits in the center console.  

• 7" fully rugged MIL-spec preconfigured Windows touchscreen tablet (refurbished/shows wear)
