What are the differences betwen a 6 pad and a 4 pad clutch ????

My car will be a street/track car (350 whp) ..... no drag ..... wich one sould I take ????

thanks !!!!

 

Shoot, at those HP levels, no need for a puck in my opinion.

I wouldn't recommend a puck clutch for anyone if they aren't planning on dragging the car at all. Check out the Exedy hyper single. That will suit your needs perfectly for those power levels and will still support you if you decide to move up to the 400-450whp range. They are a little pricey, but they are worth EVERY PENNY you'll spend.

the only argument that could be made for using a puck type in this case would be the slight decrease in parasitic loss....but really its immeasurable in this case

FC_doriftio - if you've never driven a car with puck type clutch....picture a clutch that works like a light switch. off.........ON - instantly...no feathering that ****. So if you are even thinking of using it on the street you are much better off with a heavy duty pressure plate and friction plate like either the (mentioned) exedy or an ACT or even Centerforce.

 

What, you think I am bullshitting?! I dont run a puck clutch and I am MAKING 347.5! What makes you think you need one? They wear faster and tear up your flywheel. But go ahead! Dont listen!

 

classicauto makes a great point!!

And this is my personal opinion here so don't bother flaming me, but I'd push my car around before I'd spend my hard earned money on another ACT clutch. I've had nothing but terrible experiences with them. I have used Centerforce and they were just fine for what I needed it for. But every car I've been in that was using an Exedy clutch was great! Tilton makes really nice clutches for good prices too. Or if you feel like spending the money an ORC clutch is always an option.

J-Rat, what clutch are you using?

 

I'm running the ACT heavy duty pressure plate with a street disk and it has been great for the past 3 years now. A few months after having the clutch in I had to replace the master cylinder because it started to leak. So I replaced everything and its been perfect since.

 

daily drove a 4 puck for a year

I could do it again if I had to... but it DID eat my differential. It was also a bitch backing uphill (like a driveway), etc. It will always chatter to a degree. Sitting in backups can be a pain. It's also a lot easier to stall it, at least with a lightweight flywheel... when I switched to an organic performance disc it doesn't take so much attention to keep the thing from stalling on hills etc.

On the other hand, it had an easy and powerful launch. So .1% of the time when I was racing it it was awesome.

Don't get more clutch than your car needs.

 

ACT extreme pressure plate and full face disk.
