So, there's this thing called a quick clutch master cylinder that reduces the clutch pedal tgrow by 50% and stiffens it up a **** ton, but it's only for hondas and acuras. Why hasn't anyone designed something like this for Z's all it takes is a wider master cylinder and we're in business? My brother has this on his s2000 and another car and I love it so much I wish they made one for our cars, check it out here http://iapdirect.com/omni-power-honda-rsx-honda-civic-si-ep3-quick-clutch-master-cylinder.html

 

Have a look at the RJM clutch pedal, but it's not quite what you've described, and I'm not sure why you'd want such a stiff clutch pedal.

I will grant you the Z33 clutch is one of the worst parts of an otherwise great car, and the worst of any manual gearbox car I've owned in 45 years of driving. The RJM pedal is one of the best mods I've done to my '08, though, and it transformed the car.
