Top install questions.

2 quick questions as I'm installing a KEES top that came with my car.

1. How much tension is on the hold down cables/springs? Currently the spring eye is about 1/4" from the post it goes over.
2. How thick are the pads? The pads currently have 1/2" very soft foam and a layer of cotton batting. I'm thinking of adding or replacing the foam as the pads don't appear to offer very much 'support' to the outside of the top.
