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."

Not having the spring could in fact kill the slave and the clutch over time, If the pedal does not get fully returned it could hold pressure in the system as it pressure will never get released fully into the reservoir.
This can hold pressure on the clutch itself possibly causing it to slip and will wear on the CSC bearing as it could have more pressure than normal on it all the time.

If you just get rid of the stock clutch/stock hydraulics with a proper quality set-up there is no need for aftermarket pedal springs to cover up the horrible stock clutch. A good quality clutch and hydraulics the pedal feel is very good and drives 1000 times better.
