I have an ACT HD pressure plate, ACT Street Light Flywheel, and ACT 4 Puck Clutch Disk. I've had this setup for about 6 months now, and I've always had chatter when starting from a standstill. If I was on flat ground or a downslope, and wasn't rushed, I could really take my time and it would start with minimal chatter. But if I was uphill or rushed in any way I could get terrible shuddering. I thought I might get used to it, but after 6 months of driving I decided to give this a shot.

On the newer cars the CDV is integrated into the slave cylinder. All you have to do it remove a large bolt/plug from the back of the slave cylinder and then pull the CDV components out. You can do this without unhooking the slave cylinder from the line. I would recommend unbolting it from the tranny and lifting it up so you don't make a mess. All you'll need is a 24mm wrench for the CDV and a 14mm socket for removing the slave cylinder from the tranny. Here is more info:

And here are the parts you have to pull out:





During the process you shouldn't lose any fluid, but you do let a bunch of air into the system, so you will have to bleed it. Once I had the slave cylinder back together and bolted back onto the car, I replaced my fluid with ATE SuperBlue. The whole process does not take long. Probably 5-10min to pull the CDV and 5-10min to bleed the system. Very simple overall.

After doing this I have nearly ZERO chatter. I can basically drive it like normal, and it works perfectly. It is almost like stock again. I will have no problems driving this around town without any shuddering at all. I am very happy with how it turned out. And I can't believe I waited so long to do it! Highly recommended for anyone with a puck-style clutch!

Tonight I made an attempt at combining multiple exposures. Shot using a single strobe into a 45" umbrella. Took a bunch of shots, but only chose 4 to use. It ended up looking OK, but the reflections off of a black car are very hard to deal with. I'll have to try this with a more interesting background sometime.
