Steeda Progressive Springs. Steeda springs start at a milder rate and then transition or progress at a firmer rate. During ordinary street driving, your Mustang will remain in that milder rate, resulting in excellent ride quality, but on the race track, the springs transition into the firmer rates. Specifically, the front spring rates range from 145 lbs to 225 lbs. At the same time, the rears range from 525 to 820 lbs.

Better Handling. The car wants to pitch as you get into sportier driving and brake hard; these progressive springs will help prevent nose-dive. Likewise, on corner driving, they will resist body roll! So your Mustang will have excellent 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 optimizes 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/S650 and add a set of 20″ wheels.
