Ive seen spec, CM, Competition disks all do that. I used to have an ACT 4 puck unsprung with Extreme PP in my SE-R when I first turbod it and that disk never failed. It got old and worn from many many miles of use as even I bought the thing quite used. I went to an ACT 6 puck sprung and never had that fail. Ive yet to see an ACT disk fail other than pictures from people on the forum. For street use I always go with a sprung, It will take the torture of the daily grind alot better. Solid hub disks are prone to cracking and breaking. Just go with a sprung disk this time and be done.
