Technical Clutch - Torsion Spring or Rigid?

Anyone care to enlighten me as to the difference between these?

not sure but i'd guess the rigid would be more like a 'racing clutch' with an on/off bite rather than a featherable clutch.if it is i wouldnt recommend it as i had a mate with a cossie saphire(heavy mods) and he fitted a racing clutch to handle the power and it was a nightmare in traffic as it made smooth driving nigh on impossible.like i said just a guess though

Thats sort of what I was thinking.... rigid would be *bang* 2nd *bang* 3rd as opposed to how it is now. I'm looking at a sprung one as I need to be able to drive to work without getting cramp in my left leg!

As I understand it, most clutches have the torsion springs in them. It helps take up some of the sudden movements and can make the change smoother. Rigid clutches will no doubt make it slightly more difficult to do a smooth change but be more suited for the track. If you just want it for road use you're better off with a standard clutch.

But doesnt an uprated clutch help get the power down? Wouldnt it make the cars (rather limited) power be used more efficently?

An uprated clutch can be simply a better material on the face to provide better grip, and increase in spring pressure on the cover plate to clamp the driven plate to the flywheel tighter or a combination of both.

Providing your standard clutch is not slipping it will transmit exactly the same amount of power to the gearbag as an uprated one.

The original question here related to a rigid clutch. Normal road driven plates are a two part assembly with the splined part seperate to the friction faces. There are springs between the two parts to allow a small amount of movement which can help smooth out the take up of drive. A rigid driven plate is stronger as it is effectively one part. If you are trying to transmit a large amount of power then this will be less likely to rip its centre out under hard acceleration from a standstill.

Hope this helps
