Ride height is the distance between the ground and the lowest point on a vehicle. The static ride height is the ride height when the vehicle is not moving. This is different from the dynamic ride height, which is the ride height when the vehicle is in motion. Static ride heights are typically measured with a tape measure or ruler.
The static ride height of a vehicle can be affected by many factors, such as the weight of the passengers and cargo, how much fuel is in the tank, and even temperature changes. For example, a heavy load in the trunk of a car will lower the static ride height. Or if you fill up your gas tank on a hot day, the expansion of the fuel can raise your car's staticrideheight by a few millimeters.
There are two main reasons why you might want to adjust your car's static ride height: for performance or for looks.
If you're interested in performance, adjusting your car's static ride height can help with things like cornering and aerodynamics. A lower ride height means that your center of gravity is lower tothe ground, which can improve handling and stability around corners. It can also help reduce drag if you're interested in going fast (like on a racetrack).
If you're more interested in looks than performance, then you might want to adjust your car's staticrideheight to make it look lowered (or slammed). This trend has been popularized by import culture and stance culture alike. Aesthetics aside, lowering your car too much can negatively affect its handling characteristics so be careful!
