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.

The "Road Warrior" Curb Guards work as advertised for the most part. I did not find them to be as "protective" as advertised in all the Youtube and promotional videos. Just a day after I installed my Road Warrior wheels, I hit a curb while turning at a slight angle. This damaged the curb guard as...

Had UP install the HD front bumper with the 11" LEDs. Robust steel construction, makes the truck look more aggressive but lines remain clean. This bumper is what Tesla should have equipped the truck with out of the factory! LEDs are super bright as well. Simply the best looking, best designed,...

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...

Robust carbon steel construction. Lines look very clean with the HD front and rear bumper installed. Have not seen a cleaner looking aftermarket rock slider for the CT, love mine!

I had another set carbon steel running boards on my Cybertruck for a while and finally got to see the UP Invincible HD Rock Sliders while out at XTakeover this summer. They looked so good and were noticeably more sturdy than what I had on the truck. I replaced mine with a set of these HD Rock...

While the overall weight reduction isn't much in totality, it is noticeably lighter compared to the original lug nuts.

I had an issue of the camber being no longer able to be adjusted to specs. The friends of UP took care of me. Easy to swap as well. Went to a shop yo align it and car is up to specs again and straight as an arrow. Love it! Thank you UP!

Overall, I'm very happy with the UP Forged Road Warrior 19" Wheels that I got for my new Model Y Juniper. They look great and seem very sturdy. The service and communication from Unplugged was great especially with my salesman, Shahar. It took about 3 months for me to get my wheels but it was worth...

Unplugged Performance installed front/rear sway bars on my Model 3 Performance Highland. The change was instant: less body roll, flatter cornering, better grip, and precise control. It sharped handling without hurting ride comfort. This is a great value and would highly recommended.

I received the lower compliance Aft arms today (fri), after ordering on mon. I wasn't sure I'd have time to install, since I already had a lot on my plate, but this afternoon I had a couple spare hours, it ended up only taking about 45 min, including getting the Tesla on jack stands. my...
