Removal of Clutch Assist Spring Damaging Slave Cylinder?
I got an email today from Steeda advertising an aftermarket clutch spring with 95lb/in spring stiffness rate compared to OEM 200 lb/in spring stiffness rate. And they state the following: "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."
