Why not use ACT?

I hear a lot of people talking about ACT and not to use their clutch systems. Why's that? I just had mine installed and it seems to be working ok. I just have to see if the chatter really goes away after the 500 mile brake-in (per ACT tech. i called them to make sure that my mechanic didnt mess anything up. :-) )

'Cause the ACT permits you to transfer more power through the transmission quickly. This allows people to chirp 2nd, 3rd and maybe 4th gears.

They think its fun, do it all the time, then blow their trannys.

Drive with it reasonably, and you'll be fine.

Guilty as charged...it turns out there is such a thing as "too good".

Why not? Because the stock clutch handles my NA power just fine.

It's not a question of the clutch handling the power. It's a matter of engagement. An ACT will engage a lot quicker than stock.

Less slip, more grip!

Quick engagement is what will cause problems.

An ACT clutch, if properly used, can produce quicker engagements (compared to stock) with little extra stress.

There is no doubt that quick engangements ultimately cause more stress on a drivetrain, but that's a tradeoff some will make. Taking your car to the track usually results in extra stress on the drivetrain as well, but people still do it.

"if properly used" is the key. People realize they can chirp their tires in higher gears, and do it all the time...this is when tranny's fail.

Yes and no. The first thing to fail on a stock car at the track would be the clutch. Sure, you ruin a clutch, but your tranny should remain un-harmed. With the ACT it will transmitt that force to the tranny, possiable causing damage.


All that being said, I've got an ACT and am taking it to the track tomorrow. The key is just being careful!

If your talking about your differential bearings, then how hard the clutch grabs has nothing to do with bad bearings. Driving style is not the culprit, it's the shim size.
