Our Arastradero Rear Toe Arms for Tesla Model 3 & Y take everything we’ve learned from motorsport and road car performance for over 15 years and apply it to the Tesla Model 3 & Y. We know how important it is for suspension arms to be easy to adjust, have great durability even in harsh climates, and have solid bearings rather than rubber bushings for the ultimate connection to the road. We used our experience to develop the ultimate toe arms for the Model 3 and Model Y.
Most aftermarket suspension arms are made using either urethane bushings, which are used because they are cheap – or spherical rod ends, which are ideal for performance but don’t last very long in sandy or salty environments. Our solution is to use an OEM production sealed bearing – delivering the performance of a spherical and the durability of an OE part. The sealed bearing is just like a ball joint, it is solid and has virtually no compliance, while being lubricated and protected from corrosion.
Rod ends tend to thread into a suspension arm, which makes them very easy to adjust – whereas a pressed in bearing offers no adjustment. Our solution is to use an offset thread turnbuckle allowing for precise adjustment. Rather than use jam-nuts – which always affect the alignment when locking down the nuts – our clamping system allows the alignment technician to perfectly set the alignment, then tighten the clamp bolts without throwing off the toe.
In addition, laser engraving indicates which way to adjust the turnbuckle to extend or retract the arm, saving any confusion for your local alignment technician, or for anyone trying to make some quick track-side changes. In fact – we’ve calibrated our arms so that 1 hex adjustment (1/6th of a turn) is almost exactly 1mm of toe change. This means that with our toe arms, you can precisely try different rear toe settings at the track and easily be able to get back to your starting point. This is an extremely powerful feature that none of our competitors are able to offer.
The turnbuckles are made from stainless steel – so they will never corrode or rust. The arms are CNC machined out of 6061-T6 aluminum, and anodized blue for durability and aesthetics.
These arms come fully assembled at set to the factory length. We always recommend using anti-seize lubricant to prevent any galvanic corrosion between the aluminum and steel. The toe-adjustment range is more than enough to cover any toe setting desired, even at any imaginable camber setting. Arms come as a pair of two and are warrantied for 3 years.
Don’t be fooled by imitators who have routinely copied our innovations and ideas in the performance aftermarket. MPP was the first to use sealed spherical bearings and it’s become the staple of our aftermarket suspension offerings. We were also the first to preset our arms to OEM length to help make installation a breeze. We’ll continue to find new ways to make better performance aftermarket parts, and appreciate your support and loyalty!

These arms are a great addition to the car, making precision adjustments at an event far easier than with a simple cam bolt which can be hard to accurately index. The quality is great and the fitment was perfect!
Makes toe adjustments easy and consistent. I knew I needed these when the stock toe eccentric bolt came loose at one of my events. What a pain to try and fix without an alignment rack, though a measuring tape and eyeballs came to my rescue. These arms solve that problem by allowing the adjustment to be made in the arm itself as opposed to the eccentric bolt. Much easier, much more consistent. As with everything MPP makes, they are beautiful, solid, and durable.

My alignment shop thanks you guys for providing a solid lighter weight piece with the flexibility of adjusting the toe. In all fairness I installed these at the same time with the trailing arms and camber arms. Excellent quality and perfect fitment.

Purchased this along with the camber arms and made rear alignment a cinch. Could totally dial in toe and camber as I wanted. Initial set up was relatively mild, so I came back and had them fix it – super easy. They are beautiful to boot. Win win!
I installed these today and they were almost as easy as the camber arms! Make sure you mark your eccentric bolts before disassembly and it’s straightforward. They make suspension setup a breeze for you or your favorite alignment shop, and they’re beautiful too!

My only complaint about these toe arms (and camber arms) is that I cannot show off how gorgeous they are, being tucked away behind the wheel / brake rotors. I cannot help but admire them every time I make adjustments to the damping settings on my coilovers.
Simple install, quality is top notch, no deterioration whatsoever after a winter season, allows for correction of toe and camber following a reduction of ride height.
Thank you MPP!
The alignement is great with this piece, looks good and strong. On top of it, it is light, and the bearing is something else than what Tesla offers OEM.
Another great arm and addition to tighten up the rear end of the car. Good adjustability. Just like the camber arms, make sure to add anti-seize to the threads before installing especially if you live in areas with snow/salt.
I AutoX and run HPDEs and coupled Camber, Toe and Front Upper Control Arms to dial in alignment. Well made, easy to adjust and hold positions well. Definitely the main game in Tesla performance modifications.
