Highly Recommended for all Mustangs with a Manual Transmission! Gives you a great clutch feeling, and doesn't ruin drivability - not too heavy, even in stop-start traffic!
Your 2015-21 Mustang comes with a 185 lb/in clutch assist spring installed from the factory. 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 Mustang.
Many new Mustang owners have found that taking out the stock OE spring will give you somewhat similar results as to changing to the Steeda Clutch Spring, but realistically the clutch becomes far too heavy - especially if your Mustang is daily driven. Most owners fail to realise 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 the Steeda S550 Mustang Clutch Assist Spring 35 lb/in into your GT, Bullitt, Mach1, or EcoBoost!
The Steeda S550 Mustang Clutch Assist Spring 35 lb/in completely replaces the factory 185 lb/in assist spring. Steeda's 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. Steeda's piano wire spring ensures a consistent spring rate and minimal sag even after repeated use. With the addition of Steeda's clutch assist spring, you will notice a much more linear feeling clutch - the reason being is that it takes 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.

Transforms clutch feel. Just do itBy: Andrew on 17 May 2021Best cheap mod you can make. Have done 2 cars now. Gets rid of the weird pogo stick feel. Marginal clutch effort change but major improvement in drivability. Getting stock spring off is no fun but plenty of YouTube videos on the topic. Steeda spring fitment is a no tools required task. 5 minutes all up. No idea why this isn’t the stock factory part
Steeda clutch springBy: Steve Wilsmore on 2 December 2019This spring provides a great clutch feel Would highly recommend this for the price
Steeda 2015-19 Clutch Spring AssistBy: Avi Milder on 2 May 2019Makes the clutch a bit heavier but gives much better control when changing gears as you don't get that "kick" at the end of the clutch travel that the OEM spring gives. Makes changing gears much smoother.
