Mustang springs are available from numerous sources in a dizzying array of rates and heights. Given the limitations of the stock Mustang front suspension geometry, avoid the temptation to drop the car into the weeds. It may look cool, but it will place the front roll center too low and the car will handle poorly. As a general rule, Mustangs with stock K-members should not be lowered more than about 1.5 inches from stock ride height. We used 5x11-inch 1,000 lb/in linear-rate springs from Suspension Spring Specialists, trimmed a half coil to adjust the ride height, and matched them to a pair of Maximum Motorsports race-valved front struts. Note the reinforced strut mounting ears (arrow) that are a MM exclusive.
