Personally, i would simply get the Sachs you have refurbed, put some konis on the rear, then combine it with a Whiteline ARB and Sportlines.
This is the setup that i'll have shortly, & the one that Nick is currently speccing up.
For me, it is the most driver adjustable setup available for the clio both on road/track and i dont mean in terms of suspension adjustability, i mean in terms of mid-corner, lift, slight drift, wind off lock, plant throttle, pull out of corner, repeat. Yes, it can be edgy/oversteery/nigh on dangerous at times, but a track day is about fun, not speed imho.
If you want to switch your brain off and go round & round & round as quickly as possible, get some AST's, add some camber and R888's. You'll instantly be a CS hero. If you want fun, driving pleasure and some real throttle adjustability, keep the Sachs, get them refurbed and enjoy some ar5e-twitching moments on your next trackday.
