I have the 11lb one, I think 9lbs is a wee bit too light. It def takes some getting used too with an upgraded clutch but I am glad I did it.

Sometimes in traffic I look like the biggest douchebag and if I am on a serious incline at a light it is pretty annoying, I either chirp the tires, buck like bronco , kind of embaressing but it is what it is

Whatever you do keep it one peice, I think they make two peice but if it comes apart on you, you could lose your legs (or so I have heard) (or maybe its the aluminum one? or maybe im dreaming?)

 

There is a horror story for every modification don't worry, I never felt particularly uneasy about running the Aluminum two piece 8lb Findanza for 4 years. It performed. But eventually after many miles it became warped, or the wearable/replaceable friction plate wasn’t set properly after replacement and I couldn’t hold a pressure plate to it anymore, after it coming loose two times I gave up and just put the ap1 flywheel in. Next clutch change I will probably go with the Ultra light 8.5lb SOS steel flywheel just so I don’t have to deal with the replaceable friction disc down the road again. Its a real bitch to have to drop the trans because the pressure plate keeps coming loose from the flywheel. Still never pinpointed exactly why this happened after replacing the flywheel friction disc, but I wasn’t about to experiment a 3rd time...

 

stage 5 cc? This is off topic but.. If you daily drive your car, your going to learn to hate your clutch very very quickly

i had the stage 4 and I almost wanted to never drive my car again. It grabs soo well but, it also impossible to ease the clutch in.

 

100%
I HATE my CC stage 4.. (Piece of dung)

I highly suggest ACT PP with OEM disc.

 

Before your time, there were some threads floating around of horror stories and ACT PP's causing crankwalk.

They have sense re-engineered the piece, but most people went to the CC stuff.

 

My cars not a daily driver just a weekend warrior. I'm going with the stage 5 cause I'm going to need to hold all the power I'll be putting down. I read in a few threads that the cc stage 5 isn't too hard on the pedal.

 

i have stage 4 cc w 11 lb flywheel, not too bad, you just have to develop finer control of your clutch action

 

i've had a 9lb CC flywheel from when i was supercharged (about 3 1/2 years ago) and its not too bad with my CC stge 4 six puck. At least i've gotten used to it. If you can get past the stop and starting with the lighter flywheel, the less weight in the drivetrain helps lower the shock it sees in between shifts etc...
