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.

Got these with my order of Moderate Springs and Street/Track Sway-bars and they helped reduced the offset tension of lowering the car. Great product and thank you Blake (from customer service) for answering my questions. Unplugged has been a great company to order from, top notch for sure.

Swing arms themselves can...

Been waiting for this part from UP since purchasing my coilovers almost 2 years ago and just perfect timing that old links are completely shot and this totally changed the overall feel of the car and reduced tension. Customer service is excellent and will be doing next upgrades with UP

Been riding with these coilovers for a year now on my 2020 Model 3 which is my daily driver car from home to work. I have a 2 inch drop with medium damping settings, makes the car handle and feel like a true high performance luxury vehicle. Thank you Kirk and UP team!

Tesla will just replace the entire control arm, with THE SAME inferior rubber bushing. Was happy to find these UPGRADED bushings to solve the problem for good. Excellent customer service as well.

I love these. They match the blue and black of the plaid. A small but tasteful addition to its style.
Additionally, there are some weight savings.
