I have koni shocks and eibach springs and the car handles like a go kart, get top adjustables all round and then you can tweak till your hearts content.
I replaced my bushes with standard VAG ones, purely because I've heard that polyurethane ones aren't as compliant as the rubber ones but each to their own.
If you bung the rest of it on like the roll bars and strut braces it should go round corners like a house fly.
