197 to 197 cup cost?

Hi all. Been reading up as much as I can about the Clio.
I have a 197 it's done 62,000 want to change the suspension to the cup set up. Is there any traders on here that sells all the parts, also how much does it normally set you back. I'd like it a little lower and push the footprint out by adding some spacers.

Owned the car for a few weeks now and it's awesome. Really loving the Clio!
 
I've got full set of cup springs available and I'm sure someone on here is selling dampers 40quid posted!
 
New Aftermarket Springs ~£100-200.
New Cup Dampers ~£250.
New Cup Springs ~£400.

But like others have said, used springs and dampers do come up in the classifieds from time to time so you can grab a bargain if you're willing to go used and wait until the bits come up... Personally for what a new set of Dampers cost I'd just buy new.
