Its time for a new clutch, and I've come down to either a CM stage4 modular unit or going with a southbend non modular unit. The CM worries me because of the spring issues they've had and also the fact they don't get many miles out of them for most people. Is it worth the price (an extra $400) to switch to the non modular unit?

I had to choose a new clutch when I turboed my car. I did a ton of research and didn’t want to run a CM unitnfor the reasons you stated. I ended up making the switch to non-modular with a stage 3 south bend clutch. It was money well spent! Plus in the future replacing parts will be cheaper. Modular clutches are expensive.
