Before You Destroy Another Set Of Tires…

N2itive.me – Introduces The Essential Tesla Mod!
I love my Model S but if you drive an S or X like me, you may have noticed the inner rear tires wearing out way too quickly. Even after having the vehicle aligned, the problem most often remains. With Teslas, rear inner tire wear is typically due to a combination of negative toe (where the wheels toe outward in a slight “V” shape) and excessive negative rear camber (inward tilt from the top of the wheel). Only toe is adjustable on the Tesla S and X and not very much at that. The rear wheel camber is not adjustable from the factory which is why having an alignment performed usually doesn’t help. While some negative camber is essential for good traction during cornering, having too much can wear out the inner tire’s edge. This creates a critical situation where many of us have experienced the tire quickly lose air pressure or completely blow out without warning, destroying a very expensive tire and wheel and possibly causing an accident.
It can be a bit of an illusion. A quick look or feel of your rear tire tread and everything seems fine. It’s not until you lie on the ground and look way back at the very inside edge that you see how bad your tire’s condition is. Many Tesla S and X owners like myself are getting only 5-10 thousand miles out of the rear tires. This means spending anywhere from $400 – $1,200 for a pair of new tires every few months. Not to mention spending time at the tire shop way too often.

Safety In Strength
The original rear camber arms supplied with the Tesla S/X were not the most robust design. Some owners have had issues where the camber arms will bend or break going over potholes or bumps in the road. N2itive's camber and toe arms are significantly stronger as you can see in this FEA analysis. The original camber arms suffer about 3x more deflection under less stress compared to N2itive's adjustable SX-1 camber arm. Even under far greater weight and stress N2itive's control arms won't fail.

How It Works
As you can see in the below image of the Tesla S/X rear suspension, the camber arm is fixed or non-adjustable. Whatever degree of negative camber you have is what you're stuck with and by no means are all Teslas the same! Tesla recommends having a rear negative camber of -1.75° +/-1.00° for air suspension. So that equals a maximum suggested negative camber of -2.75° to as little as -0.75° to be within their specs. For coil suspension Tesla recommends a rear negative camber of -1.25° +/-1.00° which equals a maximum suggested negative camber of -2.25° to -0.25°. It's important to understand that just because you're within Tesla's alignment range does not mean you won't suffer from inner tire wear!
OEM Tesla S/X Rear Suspension
Inherently Limited Adjustability From The Factory
Keeping your rear negative camber at -1.00° is about optimal for even tire wear while maintaining good control in cornering. If you have more negative camber than that is where you start to notice inner tire wear. Also as the rubber annular bushings in the camber arms begin to sag and break down with age you'll develop more negative camber. This is why as Tesla's get older the inner tire wear issue becomes worse.
So it sounds easy enough then, just replace the factory camber arms with a pair of N2itive's adjustable SX-1 Camber arms, have the vehicle aligned with the rear camber set to -1.00° and the problem is solved. For many Tesla owners this will be the case and only a pair of SX-1 camber arms will be necessary. There is one other thing to consider however and that is toe. As you adjust the camber, the geometry of the suspension begins to change. Adding more camber will cause the wheel to "toe in". This can generally be compensated for by turning the toe arm's eccentric bolt to push the toe arm further out. The problem is that you only have 3.5mm from the bushings neutral position to push the toe arm out. That's about the thickness of a USB cable. Not much adjustment potential at all and perhaps not enough to get the "toe" into the correct specs while your rear camber is now in an optimal position. So to deal with this we created adjustable toe arms as well.
Save Thousands On Tire Wear By Installing N2itive's Adjustable Arms!
N2itive's new TSX-1 adjustable toe arms are far more robust than the factory arms and they come with a pair of spherical and annular bushings for the best alignment and driveability. The original OEM arms came with only annular bushings. The N2itive TSX-1 gives you up to 15mm of positive toe in and 15mm of negative toe out to dial in the perfect alignment regardless of your situation. Picking up a set of both N2itive's SX-1 Camber Arms and TSX-1 Toe Arms will allow you to dial in perfect rear wheel alignment which is currently not possible with Teslas. If there is any confusion or you have questions then please check our FAQ page or reach out to us. We'll help you figure out the best solution.
N2itive's TSX-1 Adjustable Toe Arms
Design & Options
Both the N2itive SX-1 adjustable camber arms and the TSX-1 adjustable toe arms or toe links come in two variations. For the budget conscious you can get the arms constructed out of automotive grade heat treated aluminum that's been anodized red for corrosion resistance. For an additional $100 per arm you can get the insane looking electroless bright black nickel plated finish with an outstanding corrosion resistance and amazing looks. Plus those arms are constructed out of heat treated aerospace grade aluminum for almost twice the ultimate tensile strength over red version! Either way you're getting the highest quality design and craftsmanship. All arms come with brand new bushings and the required hardware to to make installation quick and easy. No need to attempt to press out your old bushings.

Brand New! N2itive’s completely overhauled SX-2 adjustable rear camber arms have been completely redesigned from the ground up! This latest revision offers big changes including our new patent pending ride height compensation bracket on all versions! This bracket allowed us to change the position of the adjuster to the inside to accommodate much easier access when aligning the car. The bracket will automatically compensate for the change in arm length at all times to maintain a stable ride height position under any circumstance. Furthermore on the electroless nickel plated black version we have incorporated our new patent pending multi-alignment recall scale, allowing the user to preset multiple alignments and then recall them without the need to revisit an alignment shop! Both firsts in the automotive world! This is really helpful for those who like to race their cars. With our multi-alignment kit installed you can set one alignment for the track, one for the drag strip and one for the street. This way you can drive your car to the track or drag strip and set the optimal alignment on location and then when you’re finished set it back to street mode to preserve the wear on your tires. One thing worth mentioning regarding this feature… In order to take full advantage of this you will need the ability to adjust your toe arms with the same multi-alignment kit on your toe arms as well. We will have our multi-alignment toe arms available early next year. At the moment we have our adjustable TSX-1 Pro toe arms which are amazing but do not currently have the multi-alignment ability.
We designed the SX-2 adjustable rear camber arms for both track use and to address the common inner tire wear issues that plague the Tesla Model S and X. We recommend using the SX-2 in combination with our TSX-1 Pro adjustable toe arms as in our Alignment Kit 1 or 2 (full camber kit). Adding adjustable rear toe arms becomes all the more necessary if you’re planning to install these on a lowered Tesla or a high mileage or older Tesla. Our SX-2 arms will allow you to add or remove rear camber to your liking. These are a direct drop-in replacement for the original Tesla rear camber arms and come preset to the length of the original non-adjustable arms. All our products are made with the highest quality materials and craftsmanship for years of endurance and come with an unmatched 6-year to lifetime warranty.
N2itive’s brand new SX-2 rear adjustable camber arms for 2012 -2020 come with both custom made spherical and annular bushings. They are the answer to the crazy inner rear tire wear we experience on the Tesla Model S and X. The SX-2 arms can be installed by the experienced home mechanic or from a local alignment shop that has experience with aftermarket control arms. The installer can review our installation instructions/video by clicking on the instruction page on our website. These parts will quickly pay for themselves in the cost of less than two tires. We can help you every step of the way, from selecting the right N2itive parts to finding an installer. Just let us know. We’re here to help and get your Tesla aligned right and driving safe! If you need anything, our customer support is always available. Contact us with any questions.
N2itive’s SX-2 adjustable rear camber arms come in three variations. The anodized red and natural versions come with our new ride height compensation bracket and a 6-year warranty.

UPDATE June-26-2022: Almost 2 years after installing the N2itive Kit. I have attached photos of my rear tires. They have about 10k miles on them. The last set lasted about 45k.
I am glad I purchased these. My Model X suffered from the famous front end shudder. I have had 5 sets of replacement front shafts and motor mounts installed, but the shudder was never totally gone. The guidance given to me was to set the suspension to low. The only problem with that is that the lower I set the car, the more it wore out the inner edge of the rear tires. Without trying to address the front end shudder by setting the suspension to low, the rear tires already had excessive negative camber that wears out the inner edge of the rear tires. These camber arms along with the toe arms allow you to totally take care of the issues and get the tires set at a good camber angle. I can now look forward to reasonable tire life. Thank you N2itive.me.

I found these adjustable control arms from a Tesla forum thread. I was searching to find a solution for the inner rear tire wear on my Model S. They come preset to the factory length so I was able to install them myself and then take it to Tesla to have them align it. The service technician at my local service center was really impressed with the quality and was able to dial in a perfect alignment. I had about -2.5 degrees of camber in the rear with the old arms and while that is within Tesla’s spec for this car, the inner tire wear was horrible. Now I’m at -0.8 degrees of camber which is also within Tesla’s alignment spec. I also got the adjustable toe arms since the factory adjustment on the rear toe is so minimal. Also let me just add that customer service is outstanding! They were always ready to answer my questions before purchasing to make sure I knew exactly what I needed. Very helpful and professional. I’m happy with my purchase.
Now that I have N2itive adjustable camber and toe arms installed and aligned I can confirm that their quality is not only looks amazing, but performs great too. My alignment has remained stable and my inner tire wear has been eliminated. Also the acceleration shudder is no longer an issue. My only complaint is that shipping took a long time since they were out of stock when I ordered.
I purchased the camber and toe arm set and had them installed recently on my Tesla Model S. I was sick and tired of running through expensive tires due to inner tire wear. I have my car lowered pretty low so lucky for me there was an affordable solution.
I saw them on display at EVFixme and thought they were so beautifully crafted and built solid. The anodized red metal was calling for me.
After installation and alignment I was shocked at how dialed in the car was. It was so smooth!
I recommend any of the products made by N2itive. The craftsmanship of the product and customer support is 2nd to none.

We specialized in Tesla repairs and modifications and always recommend N2itive products to our customers. The build quality is far superior than anything I have seen in today’s market. Don takes pride in his product and you can see it in his product and packaging. I also have N2itive products on our show car here at Evfixme. Thank you Don!
I’m a mechanic and have extensive experience working on Teslas. Last year I installed EV Tuning’s adjustable camber and toe arms on my Model S, but they are garbage. After about year I noticed that the negative camber had become quite extreme and the ride quality was not right. I took my back wheels off to review the EV Tuning arms and noticed the bushings were completely torn and not holding in place. All four bushings were destroyed after only 8-10K miles.
Fast forward I received my N2itive camber and toe arms and lowering links and I must say the craftsmanship is beyond incredible! Side by side there is no comparison. The quality is amazing. You get what you pay for and the customer support is great too. I’ve recommended N2itive parts to several Tesla owners!

They finally came! Easy to install DIY at home, except for those toe bolts towards the battery. Sawzall is recommended. Too bad no one will see those beautiful arms!
