Hey folks.. Looking for some input regarding clutch engagement difference between a single disc comparing sprung vs solid..

Looking at an ACT ME3-HDSS verses a HDSD.. It's my wife's car and needs to be easy to drive and smooth clutch engagement.. or she won't be driving to get any more groceries!

Thanks.. Mark

 

The spring in most cases will have a smooth engagement. The unsprung discs are harsh has hell. Major clapping/chatter during engagement.

 

Good to know.. Thanks!

 

Sprung for DD, especially if your wife is driving it. An unsprung hub tends to be very aggressive during clutch engagement / action. Like chirpin' tires during a hard down shift and such. A "sprung" hub tends to be way more forgiving, like mentioned above.

 

Sprung clutch for a DD. an unsprung clutch is too aggressive for the street. Just be warned the ACT HD sprung clutch is more aggressive and stiffer than stock. I have it on my Evo 9. It may take her a little getting used to

 

Buy a new OEM linning and resurface the stock flywheel and pressure plate, nothing shift better than the OEM.
ACT will be more pedal pressure and could be weird to drive for your wife.

 

I agree, there's a lot more pedal pressure on the ACT. I would only recommend the ACT clutch on wife's your evo if it is putting out a lot more power and torque to the ground stock. If not then just get a oem replacement clutch. no point in having extra pressure if its not needed

 

Agreed. Or you can go ahead and buy the Exedy "organic" clutch (i.e. stage 1, if you will), practically the same as the OE clutch. But as others have mentioned, the clamping force load or torque threshold, of the stock clutch is very low. I believe it starts to slip around 350 ft lbs of torque. Giving you little room for improvement. Someone please correct me if I'm wrong.

 

all I know is once I made the switch to e85 and crossed the 400wtq barrier is when my stock clutch gave me the middle finger and said I'm done

 

Haha
