Wouldn't that be too hardcore for normal street usage?

Would be a heavy clutch kan
Try Plotong Shawie 1.2 stock Renault klac

It will snap your left leg any point of time, have not include traffic jam infront of KLCC. It's not a performance klac. It went slipped several time when I taking my Shawie for time attack. The klac will loose traction if I do 6krpm launch, instead of wheel spin

So here's a thing for you to dig into, study how a manual clutch work, then you justify what is hardcore and what's not

Usually tebu or NS street car klac has very little different interns of mechanical design. If it's a standard klac, the most different between a performance klac and street use klac will be as below:


1) Performance clutch pad has rough and high friction power facing(pads). Usually they worn off very quickly compare to street use pads. Certain design of the clutch plate will have separated spokes to increase friction and air venting function, just like people lay grooves on their disc brake rotors.


2) Number of torsional spring, and their spring rating differs according to occupation. If it's a rally clutch, the spring does not require much calibration on high RPM, but it has to be stiff as rally engines are set to produce maximum torque at lower RPM and gear changing is extremely rapid. The more torsional spring attached to your clutch plate does not mean your clutch can take higher power, instead it produce very smooth transition when you engage/disengage clutch pedal. On the opposite note, a racing clutch usually has less number of torsional spring, rather to have fewer but longer and harsher spring to sustain extreme friction during higher RPM launch(to prevent the entire clutch plate get twisted/scrambled by the flywheel).


3) Design of the pressure plate(layman term known as clutch cover) will differ according to occupation. Aftermarket performance clutch pressure plate can be very efficient in holding the clutch friction, whist maintain very light pedal action if the pressure release plate being designed properly. Have a look at the angle of the lift springs and you'll get the idea why is it important to change the whole set of clutch instead of just changing the clutch pad itself.
Nonetheless, by having a better performance clutch, 1 can mechanically tune the car to be as close to stock kinda clutch action, without jeopardizing too much of the comfort. That however, 1 thing can never be iron out would be the contact TRIGGER point. Performance clutch will always have a harsher trigger(where the clutch is about to engage your engine, which people use to hold the car from rolling back in 1st gear infront of traffic light).
My point is, it's not about hardcore. It's about finding a suitable performance part

You want hardcore? This is hardcore. Triple plate clutch for GTR
