Clutch Question

Does anybody know what the springs in the clutch disc are for? I've always wondered but never really know...

They give the clutch a dampening/cushioning effect on engagement. As the disc is compressed against the flywheel, the springs are compressed a bit, till the drivetrain gains momentum.
If you ever drive anything with a solid center disc. The difference is very noticable.

In what applications might you find a solid center disc and what (if anything) would beneficial about them? I don't think I've ever seen a solid centered disc.

72,
I am using a McLeod "Street-Twin" 2-disc clutch in my street rod, and the discs have no damper springs...I talked to Mcleod about this and was told that they weren't needed on the twin disc setup.
Go to page six of my project journal (when viewed from the beginning), and the last entry on that page will show a picture of the clutch along with the explanation that McLeod gave me. I don't have the car on the road yet to verify if what they say is correct.

Steve
