For the Tesla Model S and X, we recommend setting the rear camber alignment to the outside of Tesla’s alignment specs.  Our exact recommendations can be found at at the top of the page. This is the optimal setting for even and improved tire wear and safety while at the same time maintaining Tesla’s recommended specifications. Tesla’s alignment spec is so broad that you can easily be “within spec” and still only get 4,000 miles out of a set of tires. This is not acceptable.

It is unlikely to get your alignment adjusted to our recommended settings with our adjustable camber arms by themselves. However every Tesla is slightly different so it’s not possible to say for certain. Installing the N2itive adjustable camber arms by themselves may reduce inner rear tire wear. However from our experience, since there is not much toe adjustment from factory, you’ll be left with too much positive toe which will wear out your tires faster than if your toe was within our recommended specs mentioned previously.  For this reason we recommend installing our adjustable toe arms to give you the flexibility to dial in the exact settings with no compromise.

If you use lowering links, drive in the low or very low positions, or if your Tesla is older or currently has extreme inner tire wear then you will definitely need both of our adjustable camber and toe control arms. If you drive a Model X then we recommend installing our Alignment Kit 1 to address acceleration shudder and inner tire wear together. That kit comes with both of our adjustable camber and toe arms as well as our RSX series ride height links to give you an ideal alignment and reduce the binding and potential damage of your front half-shafts, which is the cause of the acceleration shudder/vibration.

For a little more insight… Replacing your factory non-adjustable Tesla camber arms with N2itive adjustable camber arms will allow you to reduce the excessive negative camber of your rear wheels which is the common cause of inner tire wear on the Tesla Model S and X.  Especially if you’ve already had your car aligned but the inner tire wear persists.

However as you reduce the negative camber the geometry of the wheel changes which causes the wheels to begin to toe in.

With the Tesla S or X you can adjust the toe, but only slightly.  You have about 3.5mm of adjustment from the neutral position to try to push the toe back out slightly to the 0.10° – 0.20° setting. Generally this will not be enough to dial in the ideal setting which is why we recommend the combination of the adjustable camber and toe arms.  Alternately you can install our Alignment Kit which has both of these arms as well as our RSX series ride height links to help prevent the acceleration shudder issue as well as completely eliminate the inner tire wear issue. If you have any questions please reach out to us.

For the Tesla Model 3/Y, since they are not on air suspension you can probably just use camber arms to fix the rear inner tire wear.  If you have lowered your 3/Y then you would want to get both our adjustable 3/Y camber arms and toe arms since the geometry will change too much to be adjusted with the factory toe eccentric bolt.
