Act 4 puck race clutch help (searched)
 
So I ordered an act 4 puck race clutch, and i learn it will be horrible on the street. can anyone explain further why? How long will this last me?

Its because once u get into race clutches, Not only are they stiffer and annoying as hell to drive in traffic jams, but the range if you want to call it that that it engages is different as well. IT grabs quicker/harder and doesnt make for a very easy time driving it around everywhere

Race clutch is either On or Off. Makes accelerating from a stop light fun.
Stock(or similar) clutch is Off then you can gradually engage it again with your foot pedal.

4 puck wears out quicker than full circle disc.

you cant slip a puck disk that much either. Slip too much and goodbye flywheel, clutch and pressure plate.
If you are intent on getting a puck disk, get one that is sprung so its not a light switch, but a dimmer so to speak in terms of engagement. A sprung disk would still be abrupt but its livable.

I had a 4 puck disc. It's very easy to stall and chatters badly. Parallel parking is a nightmare, and backing up a driveway uphill is also very frustrating. If you combine it with a lightweight flywheel it's even worse.

+1 on the flywheel comment.

A 6-puck unsprung is liveable (noisy, but driveable) with the stock flywheel, a 4-puck will be even more grabby. What's the point of a digital clutch anyhow? Do you really need to hold over 400 ft-lbs of torque? For drag racing maybe, but then a lightweight flywheel makes no sense.

Since the pads are metallic, the clutch disk itself wears OK, it's the PP & FW that buckle under the abuse.

You can try to use it, but realize you just bought a costly, high risk experiment.

thanks for the advice. planning on buying an ACT street/strip clutch. since i have to drive this one home from Rotary Resurrection i cant return it. So i just wasted 350 dollars. then have to spend another 400 for a new one. fml

4 puck is not fun on traffic jams especially up hill haha. i have one on and its an on/off switch and grabs quick.

Its not the end of the world (unless its un-sprung...in which case it is lol). I learned to drive stick in my first fc, it had a racing beat 4-puck w/stock flywheel.

It IS a light switch, there is no gradual anything, essentially it was like using a series of controlled drag launches to get moving from a stop. U learn rather quickly what rpm u game to be@ to avoid stalling, (especially w/hot start issues and no fuel cut switch). If there are hills where u live I hope there are no stop lights on them; I was not so fortunate : wallbash:

If you're already stuck w/it you might wanna try it, if not for the hills it wouldn't have een so bad. It'll make u better at modulating the throttle, that's for sure. But if not, just buy a different disk, which won't cost u near 400.

in my firsthand experience the main problem with puck clutches besides harsh engagement is their very short lifespan. They're engineered to grab. They're not engineered to last. Expect anywhere from 5k-15k miles out of a puck clutch depending on a number of factors.
