Your vehicle’s suspension system serves a dual purpose – contributing to the vehicle’s handling and braking for good active safety and driving pleasure, and keeping vehicle occupants comfortable and reasonably well isolated from road noise, bumps and vibrations. These goals are generally at odds, so the tuning of suspensions involves finding the right compromise. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear.
Proper alignment geometry will extend not only tire life but also the life of your vehicle’s steering and suspension systems. Alignment problems even affect fuel economy!
Due to the wide variety of front and rear suspension systems, the cost of wheel alignments vary greatly depending on the type of alignment needed, if your car has been aligned before, or if it requires special shims to bring the alignment into specifications.
