hi, i searched and didnt find any answers...so i just want to know what the difference was between the heavy duty and the extreme?? what i'm really looking for is a dual diaphram clutch...i just like the way it feels, nice and hard...this is for a built d-series motor...so does ACT offer any dual diaphram clutches?

 

Heavy duty = 60% more pedal pressure then stock
Extreme = 100% more pedal pressure then stock

 

NO Dual diaphragm ACT pp's made for d16.
ACTION I think does make one...

What sort of power will you be making? Street car, or race car?

I am building a sleeved 77mm d16 turbo street motor with quaife lsd. I chose an XTSS to hold it because I care about driveability...
XTSS is good for 280ft/lbs of torque... thats probably about 325-350WHP on a turbo D.

If you get the 6 puck, and XT PP it's good to 400+ Ft-lbs - more than 500HP!

 

i will be putting to the wheels about 300+ no more than 350 though...i want the dual diaphram b/c i have a big family and i dont want any of them to drive it too b/c of its hardness on the pedal and i just love the way it feels on my foot...i just dont want it for that reason but a hole lot of other reasons too...

what is ACTION's website so i can take a look at what they offer...thanks..

 

I dunno if action has a web site but I do know Rocket sells them.
