New Model 3 Performance Gets UP Suspension Links For A "Perfect Alignment"!

- Alignment. What does it mean, and why is it important for your new Tesla Model 3 Performance (or any other Tesla)?
We dive deep into what an alignment does for your car, why toe, camber and caster are terms you may want to understand and take a close look at all the UP suspension links available for the new M3P and explain their benefits and why they might be right for you. Then we get the car aligned on the alignment rack in prep for upcoming testing days at Buttonwillow Raceway Park.
Simply put, alignment refers to the direction or orientation in which the wheels point in relation to the car. When performing a wheel or tire alignment on a car, there are three main adjustments that are made and optimized for your goals: Toe, Camber and Caster.
Toe refers to the inward or outward angle of the wheels as you might see from above. To simply understand this, if you were to stand up and look down at your feet, which direction your toes are pointing is the same as which direction your wheels are pointing. Toe in means your toes, or the front of your tires, are pointed toward the center, and toe out means your toes, or the front of your tires are pointed away from the center. Maintaining zero degrees of toe is great for range, efficiency and tire life, however toe in provides added stability which is why it's common for factory specification, while toe out provides faster steering response and vehicle rotation making it idea for performance and racing applications.
Camber is the angle at which your tires are tilted when viewed from the front or rear of the vehicle. If the tops of your tires are pointed to the center of the car, then you have negative camber. If they are pointed away from the center of the car, you have positive camber. You might be thinking, why would I want me tires to be anything but flat on the ground? Well, that is the goal, but in cornering, the outer tire experiences deflection which effectively lifts the inner edge of that loaded tire. The faster you go around a turn, the more deflection a tire experiences. This is where negative camber comes into play which tilts the wheel inwards to maximize the tire's contact patch with the ground. So more negative camber can add cornering grip and improve handling to a point, which is dependent on many variables including car, driver, road, tire type, and application, which is why you might see -1-1.5 degrees of camber on factory performance-oriented vehicles, while race cars might have -3-4 degrees of camber.
Caster angle is the angle of your vehicle's steering axis and is measured in degrees between the tilt of the steering axis and an imaginary vertical line down the center of the wheel when viewing from the side of the car. Having positive caster has two main benefits: 1) it forces the wheels to want to go straight which is why your car's steering wheel corrects itself back to straight when exiting a turn, and 2) it puts the tire at a tilt when cornering which effectively adds dynamic negative camber to maximize the tire's contact patch in the road when cornering.
Wheel and tire alignment is adjusted via suspension links or arms. The Tesla Model 3 Performance suspension arms limit adjustability to just front and rear toe. By adding UP suspension arms, you can add the ability to adjust camber at the front and rear as well as the added benefit of stronger arms that eliminate flexion and incorporate spherical bushings for precise steering.

The one piece of critical information that you seem to be leaving out is the weight difference between the Tesla parts that you've removed and the unplugged performance suspension components installed. If there's a weight saving then definitely the handling improvement would be worthwhile but if your parts are heavier and even with the improved Handling the weight gain would negate any performance gains so please include the weight so wsecan get an accurate understanding
Aluminium should be lighter, but yes a weight comparison would be nice
@@joey8on Any weight difference is nominal in either direction. While the billet aluminum we use is a lighter material than that of the stock steel components, our UP parts are slightly bigger/thicker to add strength and adjustability using turnbuckles and locking nuts, it brings the weight up slightly. The net result is near stock.
This was very helpful! Thanks for this great information!
Great job on this video!!
My understanding is that Tesla went to great extent to reduce the noise transmission and harness that existed in the earlier Model 3 performance suspension. Won’t the stiffer bushings in the UPP components result in a harsher ride?
Of course, if track performance is your primary goal that trade-off may not bother you.
While in theory spherical bushings can cause higher NVH levels, we, and our customers have no noticed or reported any noticeable increase. Could be that they are now enjoying the driving experience to much to notice. Not sure.
Great video! Very helpful in understanding the components. Can you please do a follow up on the 2024 performance seats in 2019/2021 Model 3s? Apparently if one uses the old seat harness the car shouldn't throw error codes... please update if you find a solution, either a follow up video or a tweet!
Waiting for an update on this too! I heard the same as you. I also heard if you reinstall the software through Tesla service mode then that could also reprogram the seat ecu’s to the car and should stop the errors.
@@MosaShoots We've heard the same. If we test it, we'll let you know here. Subscribing will send you updates.
what's the alignment machine and sensor set up at the UP shop? Is it a Hunter rack, or another brand?
Hunter
Thanks for the info! Love the mods you design
Thanks a lot! That was really helpful.
Take a shot every time he mentions “deflection” 😂
🤣 What can we say, our parts mitigate deflection 🍹
There should be a way to do these adjustments electronically on the fly.
Alignment adjustments electronically, on the fly? Sounds great... let us know when you invent it for Tesla's multi-link suspension
@@UnpluggedPerformanceTesla I was kind of hoping you would. Or adapt a system similar to Lamborghini's adjustable camber wheel hub thing.
What lowering springs are you guys running on that car? looks to be either the low or moderate option you offer.
These are the Low
Ok, NVH ? Given it's electric that will be a sensitive topic unless you track the thing all day.
In theory, one might think so, however we have not, and our customers have not noticed our reported any noticeable increases in NVH levels.
Mild, Moderate, or Low springs?
Low
This stuff should all just come standard on all performance vehicles
