ok so every rx7 ive ever driven has had a nice firm somewhat hard clutch pedal.
yet my 88 na has always had a light one. its had to clutches and pressure plates, one oem one exedy oem equivelent. it doesnt slip its got a good master cyl and a good slave. so what gives whys it so light?

 

An OEM pressure plate is going to be very light. It'll get stiffer the longer you have it, but it'll never be difficult to press.

 

I've seen that it differs from the brands. The Exedy clutch on my car was medium stiffness while an advance auto OEM one was light as hell, both held up good.

 

ok then is there a way to get a harder feel without changing the pressure plate? like are ther larger boremaster cylanders out there or something?

 

If it was replaced with a Centerforce DF clutch it will extremely light because of the design. It sucks, I had one on my car once and I counted down the days till I changed it. Yuck.

Changing out your cylinder will change pressure of the fluid but I don't know about clutch force.

 

You'd need to change the pressure plate to get a stiffer pedal. Something with a high clamping force will usually take more force to disengage. My current clutch is rated for something like 300 ft. lbs., yet it's only slightly stiffer than stock. It's still new though, so in 20,000 miles it should be quite a bit stiffer.
