| How To Improve Tesla Model Y Suspension |
1.1 Identify the Issues
Harshness over bumps: Do small road imperfections feel like jarring impacts?
Excessive road noise: Is the cabin too loud, especially on rough asphalt?
Lack of compliance: Does the car feel stiff and transmit too much vibration?
Body roll in corners: Do you desire a flatter, more controlled feel during spirited driving?
Desired ride height: Do you want to lower your car for aesthetics/aerodynamics or even raise it for better clearance?
1.2 Define Your Goals
Are you looking for a luxurious, cloud-like ride for daily commutes, or a sportier, more controlled feel for occasional spirited driving? Understanding your priorities will guide your choices in suspension components.
Step 2: Simple Adjustments for Immediate Improvement
Sometimes, a significant change isn't necessary. Small adjustments can make a noticeable difference.
2.1 Adjusting Tire Pressure
The Quick Fix: One of the easiest and most cost-effective ways to improve ride comfort is to adjust your tire pressure. Tesla often recommends a higher PSI (pounds per square inch) for optimal range and handling. However, reducing the pressure slightly can significantly improve tire damping, making the ride softer.
Recommendation: Elon Musk himself has suggested that reducing tire pressure from 42 PSI to 39 PSI can improve damping. Experiment with pressures a few PSI below the recommended maximum, but always stay within the safe operating range specified by your tire manufacturer. Check your owner's manual or the tire sidewall for minimum and maximum pressures.
2.2 Inspecting and Maintaining Existing Components
Tip: Focus on clarity, not speed.
Tire and Wheel Condition: Regularly check your tires for uneven wear and your wheels for any damage or misalignment. Worn tires or misaligned wheels can contribute to a harsher ride and increased noise. Get an alignment if needed.
Lubricating Seals: Squeaks and creaks from the cabin can often be mistaken for suspension harshness. Lubricate all rubber seals, especially where glass meets the seals, with silicone grease to eliminate these noises and create a quieter interior.
Step 3: Upgrading Your Suspension Components
For a more substantial improvement in ride quality, you'll need to consider aftermarket suspension components. These generally fall into a few categories: lowering springs, coilovers, and air suspension systems.
3.1 Lowering Springs
What they are: Lowering springs replace your factory springs and are designed to reduce the vehicle's ride height. This can improve aerodynamics and give the car a more aggressive stance. Many aftermarket lowering springs also offer a slightly softer initial spring rate compared to stock, which can improve comfort over small bumps.
Benefits:
Improved aesthetics with a lower stance.
Potentially better aerodynamics, leading to a marginal increase in efficiency.
Can reduce body roll to some extent.
Considerations:
While some lowering springs prioritize comfort, others might be designed for sportier handling, which could still result in a firm ride. Research reviews thoroughly.
Often, you'll want to pair lowering springs with aftermarket shocks that are valved to match the new spring rates for optimal performance and longevity.
3.2 Aftermarket Shocks/Dampers
What they are: Shocks (or dampers) control the oscillations of the springs. The factory Tesla Model Y shocks are tuned for a balance of sportiness and stability. Aftermarket shocks can be specifically designed for comfort, with softer valving to absorb bumps more effectively.
Benefits:
Significantly improved ride comfort by reducing the transmission of vibrations and shocks to the body.
Can be individually adjusted on some models to suit your driving style.
Considerations:
Pairing comfort-oriented shocks with your existing springs might work, but for the best results, they are often designed to work in conjunction with specific aftermarket springs.
3.3 Coilovers
What they are: Coilovers are an integrated shock and spring assembly that allow for adjustable ride height and often adjustable damping. They offer a more comprehensive solution than just springs or shocks alone.
Benefits:
Highly customizable ride height, allowing you to dial in your preferred look and performance.
Adjustable damping (on many models) means you can fine-tune the stiffness for comfort or sportiness.
Can dramatically improve both comfort and handling, offering a "best of both worlds" scenario.
Popular Options: Brands like KW Suspensions (V1, V3, V3 Leveling) and Mountain Pass Performance (MPP Comfort Coilovers) are highly regarded for their Model Y coilover solutions, with many focusing on enhancing comfort.
Considerations:
Coilovers are a more significant investment than just springs or shocks.
Installation can be more complex, often requiring specialized tools and expertise.
Proper adjustment of ride height and damping is crucial for optimal performance and comfort.
3.4 Air Suspension Systems
What they are: Air suspension replaces traditional coil springs with air springs (airbags). These systems use an onboard compressor and computer to adjust air pressure in real-time, providing a highly adaptive and comfortable ride.
Benefits:
Unparalleled ride comfort, as air springs can absorb road shocks much more effectively.
On-the-fly adjustable ride height, allowing you to raise the car for rough terrain or lower it for improved aerodynamics and aesthetics.
Can significantly reduce pitching and rolling.
Some systems claim to increase range due to improved aerodynamics when lowered.
Considerations:
Air suspension is generally the most expensive suspension upgrade option.
Installation is complex and typically requires professional expertise.
More components mean more potential points of failure compared to passive coil setups, though modern systems are quite reliable.
Step 4: Professional Installation and Alignment
Unless you're an experienced DIY mechanic with the proper tools, professional installation is highly recommended for suspension upgrades, especially coilovers and air suspension.

4.1 Why Professional Installation?
Safety: Suspension components are critical to vehicle safety. Incorrect installation can lead to dangerous failures.
Precision: Proper torqueing of bolts, correct spring compression, and careful routing of lines (for air suspension) are essential.
Expertise: Experienced technicians can ensure all components are installed correctly and that your new suspension operates as intended.
4.2 The Importance of Alignment
Post-Installation Requirement: Always get a wheel alignment after any significant suspension work. Changing springs, shocks, or coilovers will alter your vehicle's alignment settings (camber, caster, and toe).
Benefits of Proper Alignment:
Prevents premature tire wear.
Ensures optimal handling and stability.
Maintains the vehicle's straight-line tracking.
Step 5: Post-Installation Adjustments and Fine-Tuning
Once your new suspension is installed, the journey isn't over.
5.1 Ride Height Adjustment (Coilovers/Air Suspension)
Coilovers: Most coilovers allow you to adjust the ride height. Experiment with different settings to find the sweet spot between aesthetics, comfort, and performance.
Air Suspension: Air management systems allow you to program various ride heights for different driving conditions (e.g., higher for rough roads, lower for highway cruising).
5.2 Damping Adjustment (Adjustable Coilovers/Shocks)
If your new suspension has adjustable damping, take the time to experiment with the settings. Start with the manufacturer's recommended comfort settings and then make small adjustments, noting how the car feels over various road surfaces. A few clicks can make a big difference!
5.3 Drive and Evaluate
Take your Model Y for drives on different types of roads – smooth highways, bumpy urban streets, and curvy roads. Pay attention to how the car handles and feels. This feedback will help you fine-tune your settings.
