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.

This is by far the best front fascia out there and its makes the Model 3 look so much better! It gives it a much sportier look and I get comments on it all the time.

These are a great set of wheels. I purchased them to replace my OEM 2024 M3P wheels. I went with the 19x9.5 in satin black. The wheels are very lightweight and durable. I wrapped them in Michelin Pilot Sport 4S summer tires. The wheels are great on the street for daily use and I have used them at...
