This high-rate spring is what causes such a vague and disconnected clutch pedal feel. The clutch pedal travels in a circular arc, with the spring assist in the middle of that clutch pedal travel. The middle of that motion compresses the spring initially and then allows it to extend after the first 30 degrees of travel. The combination of a high-rate assist spring and motion of the pedal during engagement causes a non-linear and sometimes confusing pedal feel. Having a non-linear pedal feel makes it hard to modulate the clutch on your S197 Mustang.Many Mustang GT, V6 or Boss owners have found that taking out the stock OE spring will give you somewhat similar results, but realistically the clutch becomes far too heavy especially if your Mustang is daily driven. Most owners fail to realize the prolonged effects of simply taking out your factory OE spring and not replacing it with another spring. By negating your factory clutch assist spring you will notice chatter/NVH from your clutch pedal. Your clutch pedal will never fully return to stock position without any assist spring, and over time your slave cylinder may begin leaking due to constant pressure on its seals from the clutch pedal not returning to the stock position. Avoid these problems in the future by installing our Steeda S197 Mustang Clutch Assist Spring 95 lb/in into your GT, V6 or Boss.Our Steeda S197 Mustang Clutch Assist Spring 95 lb/in completely replaces the factory 200 lb/in assist spring. Our engineers have honed in on just the right amount of spring rate to get you the perfect clutch pedal feel you look for in a Mustang. This assist spring is manufactured from piano wire that naturally has high tensile strength and high elastic qualities. Our piano wire spring ensures a consistent spring rate and minimal sag even after repeated use. With the addition of our clutch assist spring, you will notice a much more linear feeling clutch - the reason being is that we take out much of the influence involved in your clutch pedal motion caused by the assist spring, allowing you to feel exactly what is happening with your clutch engagement.
