Even though my 7 jdm is stock, I have fitted the exedy heavy duty... Smooth in gear changes, daily driving is good not hard pushing & releasing clutch pedal, no high rpm lockout & responsive when shifted in the next gear. There would be more positive feedback but you have the idea, no cons as of yet such as slipping etc... I launch my car a few times & no burning smell etc.. Love it

 

Qm hydraulic imo
