Anyone used these

I wouldn't use them personally. Save up a bit more and go for something that has the option to set your own damping up.

'Quality & Value'

the value means budget lol and I think suspension isn't one that you should skimp on.

If it was a normal car, they'd be fine, but with the Clio Rs known for handling, I wouldn't want to spoil it
 
Probably going to go gown the springs route after some research I think ebach are my best bet due to only lowering 25 20 and ride not compromised too much. How much are the spam springs. Any ideas if there any good what do they lower by?
