Billet Adjustable Rear Toe Arm Set for Tesla Model 3 & Model Y

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. 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. 

Damper life on a vehicle depends on many variables such as driving prolonged periods of time on rough 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 damper’s range, it can be typically felt with noticeable degradation of ride quality resulting in rough and bouncy driving.

Our springs have been very carefully developed to avoid such an extreme. 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. 

We recommend very strongly that you get your wheel alignment corrected after fitment of any lowering springs.

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 tyre 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 tyre wear for handling) or more economical (trading off maximum grip for better tyre wear).

Please note that while alignment shops can adjust these settings to your tastes, there is a limitation on the ranges of adjustment.

Yes, your ground clearance will be adjusted by equivalent lowering value of the lowering spring you select.

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, tyre sizing is a very important topic; specifically, maintaining the correct ratio of width and diameter when replacing / upgrading tires.

All Teslas are available from the factory with several wheel options, typically in three different diameters. Despite the different sizes, the overall tyre size ratio is almost identical, and as it can affect the height of the car, this ratio plays a role in how your car will look post-spring installation.

We’ve seen several owners install tyres 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.

So, when choosing tyres, we strongly recommend keeping within the very precise margin for overall diameter as spec’d from Tesla.
