Q: What does a sway bar upgrade actually do for a Model 3?

A sway bar ties the left and right wheels together so the car leans less in corners, which keeps the tires flatter to the road and working evenly. The Stage 1 kit uses adjustable front and rear sway bars with three settings at each axle, so you can tune the balance between understeer and oversteer to your roads. Less body roll keeps the platform composed and transitions quick, so the car feels planted where a stock Model 3 rolls and washes out.
