Clutch type wtb?

[D-UNIT]

I'm going to buy a new clutch soon. I need help deciding. Should I go Carbon Kevlar or Copper metallic. Both have sprung centers. The CK is a stage 4 and the CM is a stage 5 , both are the same price. What is the difference between the two materials (pros and cons)?

[D-UNIT]

OK I know the difference between the two materials. I'm looking for anyone with experience w/ them. I.e. copper metallic is to harsh or carbon kevlar burns up fast. I'm building up a 300+ hp KA engine. I'm running a CK clutch right now but I want to know if it is going to be enough in the long run.

uhh...get an ACT street/strip...i think that should cover u boss...lol stage 5 seems like a bit much...i think the street/strip is supposed to cover up to 310 lb/ft torque

ACT clutches are great but I'm partial to ClutchMasters. You see when I bought my 240 , the owner informed me that it had a Clucthmasters stage 3 carbon kevlar disc. He said he didn't know if it was still good. Well upon putting brand new tires on I found out that the clutch very much indeed "GOOD"!! I learned I could scratch 1st , 2nd , 3rd AND!! 4TH gear!!! I was impressed. I've never driven a car that could chirp 4th gear. Heck it even chirps 5th when I mishift out of 2nd lol. So here I am almost two years (in august) later, I went drag racing on friday. I made about 12 passes all consistent within 15.0 - 15.5 , and every pass I scratched second and third with no slippage. Same clucth. I'm sold.

So now my trans is going. I got a used one on the side already ($100). My friends won't help me put it in till I get a new clutch. Even though I swear by my old one . They say " No , your going to open it up and it is going to look mangled. Change It , or don't waste our time!!!"

I'm going to get a lightweight flywheel too. The reason for this thread is because I've seen copper metallic clutches eat the heat sheild off lightweight flywheels. I want to know if anyone's had or heard of a similar problem.

Ok here are my two choices - stage 3 - which I love , especially the stock pedal feel Or - stage 4 - copper metallic , no burn , harsher , but more holding power. Not stage 5 that is full race unsprung center. thanks for the response MainEvent.
