1969 Porsche 912 Seats

[redoil]

I'm a new-bee.
I am re-doing my bucket seats and have pull-over new vinyl.  I took off the old (original) stuff and found that the old coil springs are all sagged.  Before I put on the new upholstery -- is there any way to get some "spring" back in my springs?

I don't do car seats but my guess would be either new springs or more padding. I'm sure someone on this site will tell you the right way.
