Steeda Progressive Springs. Steeda springs start out at a milder rate and then transition or progress into a firmer rate. During normal street driving your Mustang will remain in that milder rate resulting in great ride quality, but on the race track, the springs transition into the firmer rates. Specifically, the front spring rates range from 145 lbs up to 225 lbs. While the rears range from 525 to 820 lbs.
Better Handling. As you get into sportier driving and brake hard the car wants to pitch, these progressive springs will help prevent nose-dive. Likewise, on corner driving, they will resist body roll! So your Mustang will have great handling. Just as important, when you go to launch, the Mustang is not going to squat, it's going to set and it's going to go!
Car Stance. Steeda Mustang Sport Progressive Springs optimize the center of gravity and suspension geometry. An overall improvement of appearance, lowering the car just over 1" at the front and an inch at the back. So you get the perfect rake. These will clear stock wheels, or complement your S550, and add a set of 20" wheels.
Quality Engineering. Steeda's experience and expertise in high performance street and racing suspension systems is second to none. Steeda progressive springs are all in house engineered and custom made to their exact specifications. They are developed using advanced proprietary CAD data and exclusive 3d modeling settings; all the while, manufactured under rigorous QS-9000 & ISO 9001 certifications.
