Q: What is Caster?
Caster is the forward or rearward tilt angle of your steering axis. For example, on the Model 3 Performance Multi-link Suspension the steering axis is relative to the placement of the upper and lower ball joints and their offset relative to a vertical line. So if you were to draw a line between the upper and lower ball joints and measure the angle of that relative to a vertical line through your hub that would determine your caster.

Excellent fitment, packaging, and overall product. The stock bar compared to UP's is no comparison. Installed on medium setting and will be changing it to the stiffest this weekend, which is extraordinarily easy to do.

Tesla Cybertruck Heavy Duty Rear Bumper with Hardcore Trailer Hitch Receiver - UP INVINCIBLE®
RATED 5.0
Had UP install the HD rear bumper with hardcore trailer hitch receiver including flood lights. Utility is awesome, the arms are robustly built and carry my full-size spare, a 20" beadlock wheel with Wildpeak AT4Ws with ease. No rattling whatsoever, the tire is locked in. Swing arms themselves can...

Exactly what I wanted. Much better appearance. Beautiful stance. Both stiffer in the corners and smoother on the regular road imperfections. Feels more tuned and prepared. Will recommend to all my Tesla owning friends.

Coupled with the FUCAs, the rear arms really help do a proper alignment. Definitely get these if you want to get a perfect alignment for your car, and better than OEM. I put -2 camber in the rear for my track day yesterday and achieved phenomenal handling in the corners. I also tried it out in drift...

Absolutely love it. Compliments on it all the time. I've had people compare the look to a Porsche or even a McLaren. Beyond the good looks, it also gave me some better front downforce. I often take my car to the track and some hard canyon runs so the functionality of it was pretty important to me.

The Air suspension upgrade kit works well on my refreshed Raven Model X with the upgraded Air Suspension kit. The suspension setting on Low not only improves the look but also benefits from higher efficiency with the advantage of location based auto raise function....

These wheels are insanely light and strong! And, they look the bomb! If I didn’t look while picking them up, I would have thought they are carbon fiber!
The same spec as was originally used on the Bionic Phoenix Model 3 race car! I put in my fastest time at Buttonwillow on these wheels running...

The UP-05s from Unplugged are a game-changer for my Tesla Model 3 Performance. These wheels have transformed my ride, making the car feel incredibly nimble whether I'm zipping through a Taco Bell drive-thru or carving up some twisty country roads. The aesthetics are on point - these wheels look sick...

I ordered my satin graphite UP x BBS Flugplatz wheels in March 2022 and got them delivered and installed in June 2022. The wheels were ceramic coated after delivery. I am running 255/35 Falken tires (all-seasons). These wheels have an amazing design and paint finish. They do a great job at exposing...
