@TWR1
Do have an RS2 with the KW suspension?.
I'm asking this because I tried to find out if the rearsuspension has an attachment for the antirollbar at the rear, which isn't a standard option, actually not an option at all, but just a sell out from TWR bankrupcy, and like me who got it from Renault Sport directly.
And which one did you order from KW, because they sell two types, but their builtyears do not match with the builtyears of the actual RS1 and RS2. I tried to get the correct info from KW directly, but in fact it's a bunch of w#nkers at KW, who do not respond to any mail, even when I sent it officially from Renault.
We had some questions concerning the springrates, because they were opposite of what we would have expected, and about the uppermount stiffness.
I have a few doubts if the RS2 would have any benifits from the KW suspension concerning the money you need to invest.
(The RS1 benifits from the suspension, but that is because TWR did a crappy job on them in the first place, so that wasn't too difficult)
Since they didn't respond at all, I can only advice to not put them on your RS2. I even have doubts if they actually tested them on a RS2.
For this matters I lean more towards a suspension from Leda,
which also have adjustable bound and rebound, and from what I read here on the forum, a kinda service for tuning them.
Correct me here if I'm wrong, since I didn't have any contact with them yet.
Actually I'm not sure I'm going to change the suspension on my RS2 at all.
I experience the RS2 standard suspension quite balanced, apart from the flexing uppermounts, which are too soft.

Don't know if you got a RS1 or RS2.
For the RS1 get the new subframe, and mount the KW.
For the RS2, since you also drive flat beaten beetles, you will have more benifits from the rear torsionbar 14mm, which balances your car more like the beetle. You get rid of the massive understeer.
