Sounds like they're too stiff.
Put couple of mates in the back seats and I bet it gets better...

Whichever has fuel

would ya say that standard rear shocks would be stiffer than ktec ones ? have my old ones lying in the shed.

cant be mate, my friend fitted ktec coilovers as well and had exact same problem. id say just because there cheap
1 other person in the entire world having the same problem as you is not conclusive proof LOL. In the same way as plenty of happy ktec customers (I gather they all exist on this Renault UK club thing) doesn't prove that you're not having issues.
But that's irrelevant because I still kind of agree with you. "Cheap" doesn't necessarily mean the manufacturer can't do the maths/theory to pick spring/damping rates just as well as AST (gold dust as far as CS is concerned). The Engineers at Renault will be no less qualified or experienced than the Engineers at Aston Martin for example. They just have different budgets to make the same thing. Cheap just means they have little control over the damping rate that the damper actually produces. Whether that's poor manufacturing tolerances, seal packs that are prone to leak, a batch with not enough gas pressure blah blah blah you end up with an "under damped" rear suspension.
Out of curiosity, would you call it "skittish"(cause = springs are too hard) or does it just "continue to bounce for ages" after hitting a big bump (cause = not enough damping or too soft springs + sensible damping)?
Sell them to someone who thinks "lows" are "sik" and buy some low mileage second hand Bilsteins, Gaz, AP, BC etc

I'd say because there's excess suspension travel that the issue is with damping rather than the spring rate being too high, so basically as you've said it could be crap dampers by design or by damage. Probably a bit of both.
Is there though? (I don't know either, I just play devils advocate in all the really vaguely worded threads.)
I'm out on the basis some things are best kept simple.
Buy some new coilovers and hope that one of the hundreds of differences between the new & existing (not just the damper units, but the long term build quality, how the interact with your specific car blah blah) ones just happens to be the root cause of your problem.
