Tesla Model 3 / Performance – Dual Rate Linear Lowering Springs Set

Neither. It is a third category. The dual rate nature of this product is a direct descendant to motorsports “stacked’ spring setups. A stacked spring is two linear springs of differing spring rates and lengths that are stacked together with a predetermined location for a transition point between spring rates. This strategy employed on high end motorsports suspensions provides predictable results yet allows advanced tuning of handling characteristics by using two independent linear spring rates. The dual rate spring we offer is of equivalent concept. It employs two specifically engineered linear spring rates with a specifically located transition point between the two rates. Therefore, it is more linear spring than progressive spring in nature, yet is a third category.

Our Dual Rate Lowering Springs offer the following drops: 2017 - 2024+ Model 3 (All Models)* Mild: .7" Drop Moderate: 1.5" Drop Low: 2" Drop *Slight variances in drop depending on vehicle production variables

We warranty our spring kit with our lifetime product warranty. Tesla’s warranty covers their products but Tesla does not keep inventory or purchase non Tesla products for warranty repair, they only warranty what they manufacture.

A vehicle’s comprehensive warranty as a whole may not be voided due to use of aftermarket parts per the Magnusson-Moss Warranty Act (https://www.sema.org/sema-enews/2011/01/ftc-validates-right-to-install-aftermarket-parts). However, a manufacturer may require a customer to pay for parts and labor for a repair if there is direct causation between a customer’s alteration and the product or service repair being requested. It is in both manufacturer and customer’s interest to follow logic and reason so that the system of good faith is not abused. If this topic interests you please read the law as well as your warranty documentation. Ultimately we are Tesla owners and enthusiasts, we are not lawyers and cannot provide legal advice.

Shock life on a vehicle depends on many variables such as driving prolonged periods of time on unpaved surfaces in rural routes, high performance driving on winding roads, motorsports use, and/or other high impact situations. It has been reported at times that extreme lowering of a vehicle can in instances shorten the life cycle of shocks for example. If you research online you may see examples of extreme cases in which a car was lowered well outside of the safe operating range of the shock valving, and doing so can lead to excessive wear. In those extreme cases, when driving a vehicle that is too low and operating outside of the shock’s range, it can be typically felt with noticeable degradation of ride quality resulting in rough and bouncy driving. Our product does not fall into such an extreme and this particular topic has shades of gray in between the extremes. There is ultimately no definitive formula in determining how much or how little wear a shock will incur over time because shock wear encompasses many use factors, height being one of them. Out of an abundance of caution, we encourage that precaution is taken with regards to the possibility of more frequent purchasing or rebuilding of shocks or related components in correlation with driving style and lowering. This topic is largely similar to the understanding that when driving aggressively tires will wear faster and tire costs may increase as a result of more aggressive driving. Ultimately if this is of concern then lowering your car may not be the right choice for you.

Every vehicle’s alignment correlates to ride height and adjusts freely as height changes. For example, if you ask any Model S or Model X owner with air suspension, they will tell you that they love how the car looks and performs when driving on the lower range of settings. They will also often advise that they experience some additional tire wear from negative camber. What they are experiencing is that the car is aligned at a fixed height, and when air suspension lowers the car lowers and the alignment changes relative to height. A lower height typically results in more negative camber which can both increase handling and decrease tire lifespan. Getting a car re-aligned allows each owner options for setting an adjustable alignment characteristics. This enables you to to inform your alignment shop as to whether you would like alignment to be more aggressive (trading tire wear for handling) or more economical (trading off maximum grip for better tire wear). Please note that while alignment shops can adjust these settings to your tastes, there is a limitation on the ranges of adjustment.

The benefit of dual rate linear springs is that there are two discrete spring rates. As a result, we were able to design a firmer secondary rate that is stiff enough to prevent excessive sagging when extra weight is applied.

Yes, your ground clearance will be adjusted by equivalent lowering value of the lowering spring you select. We address this question in greater depth above within the subject “which version should I get?”. Cars of factory height and of all shapes and sizes unfortunately sometimes encounter situations in which they scrape and/or incur damage. In such cases the cost of that damage is the responsibility of the driver and not of the vehicle or aftermarket part manufacturer. When choosing to lower your vehicle, we encourage you to be aware that you are reducing ground clearance and therefore increasing your chances of impact. Drivers of previously low cars tend to understand this inherently, however if this topic is new to you please take consideration of all facts before making your decision.

For any car, tire sizing is a very important topic; specifically, maintaining the correct ratio of width and diameter when replacing / upgrading tires. Model 3 is available from Tesla with several wheel options, in three different diameters. Despite the different sizes, the overall tire size ratio is almost identical, and as it can affect the height of the car, this ratio plays a role in how your Model 3 will look post-spring installation. We’ve seen several owners install tires which have significantly different overall diameters than suggested, which causes the vehicle to either sit higher or lower than the height for which our springs are intended. When choosing tires, we strongly recommend keeping within the very precise margin for overall diameter as spec’d from Tesla.
