The problem they had with the 228 comes down to the electronic damper software. Not the shocks or Springs or bump stops. Although changing them would help but what is really needed to fix the floatiness and instability at the limit is the software. Install dinan shockware and run the comparison again. It's awesome and I recommend it to everyone.

EDIT: I claim it comes down to the software more than the OE hardware because someone with a 235 had upgraded shocks/springs/stops and still has these undesirable extra movements.

It's true the car likes to push and understeer. Almost all modern cars from the factory do. The staggered tire set up doesn't help. But with the software the car is much more likely to rotate.
