Tesla Model 3 Suspension Upgrade Review: Improved Ride Quality

Addressing the Tesla Model 3's Ride Comfort Issues

Many Tesla Model 3 owners report that the car's ride comfort doesn't meet expectations, especially concerning small road imperfections. Sharp jolts from minor potholes or even road paint can transmit significant impact through the cabin, leading to fatigue on longer journeys. This often stems from the characteristics of the stock suspension system. This review details a suspension upgrade aimed at enhancing the Model 3's ride quality.

Pre-Upgrade Assessment of the Model 3 Suspension

The vehicle in question was a 2022 Tesla Model 3 with a mileage that indicated good overall condition. However, the owner consistently experienced discomfort from even minor road surface variations. The service team decided to replace not only the main suspension components but also the anti-roll bar links. These links are crucial for managing body roll during cornering and can significantly impact both ride comfort and handling if worn or damaged. A thorough inspection of the entire undercarriage before the upgrade is essential for ensuring customer satisfaction.

Tesla Model 3 Suspension Upgrade Process

The suspension replacement follows a systematic procedure. Key steps include disassembling the upper control arms and knuckles at the front, removing the anti-roll bar links, and then detaching the original suspension units. For this specific vehicle, the presence of aftermarket wheel covers streamlined the process by eliminating the need for their removal.

Installation process:

1. Disassemble front upper control arms and knuckles.
2. Remove anti-roll bar links.
3. Detach original suspension components (front and rear).
4. Install new Highland genuine suspension units and springs.
5. Perform wheel alignment.

Highland vs. Stock Suspension: Key Differences

The Highland suspension upgrade offers a noticeable improvement in damping adjustability and responsiveness compared to the factory setup. It's important to select a suspension system tailored to the specific Model 3 trim (RWD or Long Range), as their weight distribution and center of gravity differ due to battery placement and capacity. Choosing a performance suspension that matches the vehicle's engineering is vital for achieving true ride comfort improvements, rather than just opting for adjustable damping.

Post-Upgrade Performance and Owner Feedback

Following the upgrade, the owner reported an immediate and significant difference. The most striking feedback was that road imperfections felt 'rounded' and were absorbed much more smoothly. The previous sensitivity to minor height differences, like road paint, was eliminated. This aligns with consistent feedback from similar upgrades performed by the service center, highlighting improved shock absorption and a substantial reduction in intrusive vibrations during daily driving.

Cost and Time for Tesla Model 3 Suspension Upgrade

A full suspension replacement typically takes between 4 to 6 hours. This includes parts preparation, ensuring front and rear balance, and final wheel alignment. While it can often be completed in a single day, scheduling a bit of extra time is recommended. The cost varies based on the chosen components and any additional work, with a full replacement generally ranging from approximately ₩1,200,000 to ₩1,800,000 in Korean Won.
