Coil Springs, Lowering Springs, Lift Springs, Sport Springs, OE Ride Height Springs
Do lowering springs improve performance?
Assuming the springs are good quality, yes. Typically, the lowering springs have higher spring rates, which improves weight transfer, responsiveness and acceleration.
Do lowering springs hurt ride quality?
No. Most street and sport lowering springs are designed to ride as close to factory as possible, maintaining similar suspension travel, and minimal (up to 15% higher) spring rates. Additionally, most progressive rate street and sport springs keep the factory spring rates for the first 25-20% of spring travel, which preserves that factory ride quality.
Can I improve my spring performance without lowering my vehicle?
Yes. Several brands offer “OE Ride Height” performance springs that provide the improved handling characteristics, without lowering the vehicle stance.
Do you need an alignment after replacing springs?
Yes. You will need an alignment after replacing springs, whether lowering, stock or lifting.
