Need? Or want... Hydraulic throw out bearings eliminate unneeded linkage that creates friction & tends to wear out... On a car a buddy has owned since high school he was constantly complaining about how hard the heavy clutch was on his knee... He'd tried a few different clutches, all the pivot bushings were new & no matter what he tried he just wasn't happy with it... I suggested trying a hydraulic clutch & the difference was amazing probably 25% less effort to operate the clutch...
Go ahead, tell me how tough you are & how your a manly badass are & that you still drive a heavy clutch & don't care...
The reality is my buddy has owned his Coronet R/T since 1977 & in the last few years his knee bothered him enough that he wasn't driving the car... We converted the clutch to hydraulic kept the old clutch & now he drives the car again..
