Which technician is correct regarding the adjustment of coil springs for a low ride height?

When discussing the adjustment of coil springs for a low ride height, it's important to understand that altering the ride height of a vehicle through the adjustment of coil springs is not a recommended practice unless the springs are specifically designed to be adjustable. In most cases, coil springs are engineered to provide a specific ride height and altering this could negatively affect the vehicle's suspension geometry, handling characteristics, and overall safety.

Technician A and Technician B likely have differing but incorrect interpretations of the proper methods to lower ride height using coil springs. If both technicians suggest using methods that can compromise the structural integrity or load-bearing capacity of the coil springs, or if they think that simply cutting or modifying the springs is a viable adjustment, their reasoning would not align with standard automotive practices.

To maintain the vehicle's performance, safety, and comfort, it is essential to use properly designed aftermarket or replacement springs intended for the desired ride height adjustment. Therefore, neither technician’s approach would be correct in the context of safe and effective coil spring adjustment for a low ride height.
