I just got my clutch and flywheel replaced, and yes i have chatter of course. I have the Competition Carbon Kevlar stage 2 clutch and steel lightweight flywheel. I feel a big difference in accelrating in 6th gear at low rpms the car does get going faster, but imo its not really worth all the chatter at less than 1800 rpms. The only gears that dont do it are 6th and 1st, I do like where the clutch grabs though. Lower than stock, about right off the floor feels like its ready to go when the clutch grabs unlike stock when it feels like the car doesn't have enough power. Eventually i will get used to the chatter though. I cant do 3rd gear turns anymore i have to throw in second to keep my rpms above 2k. Without the chatter this setup is perfect.
I did do my reserch so i knew chatter comes with a lightweight flywheel, but i didnt think it was this bad. I could always hear the chatter on the stock flywheel but the exhaust would drown it out. This chatter takes over my stereo on 24. I guess if i could i would go back to stock flywheel and keep the stage 2 clucth but i will deal with it and just shift later. I just wanted to post a little review and ask what is Carbon Kevlar?? Is at some mixture of carbon fiber and a bullet proof vest What makes it so special. All the tech kept saying is wow i cant believe its carbon Kevlar.

I have the competition stage four and it just has a lot of chatter ! You have to pay to play !!! Good thing you didn;t get the stage three !! I had to replace it twice within a month !

why did you have to replace it????????

I guess with the three you really , really have to break it in !!

how long did you break in your stage 4? i have driven about 300 hundred miles

After I had the problems with the previous two I did like 1500 miles to be extra safe !! Those installs add up real fast . JUst take your time and break it in right and wait for like 1000 to be safe .
