I hated the RFTs and the harsh ride so much that when I changed to Yokohama Advan Sport non-RFTs, it was like driving another car. The 123d with M Sport pack has a harsh ride to start with.
Now, while it might not point as directly into corners on mirror-glass roads, who drives on these every day? Moreover, I am not doing track work. The reality is that Australian roads, apart from most motorways, are far from smooth.
I've done about 4,000 kms on the Advan Sport tyres, and whether on dry or wet roads, on straights or cornering, I am convinced of the wisdom of the decision to get rid of the run-craps.
Bilstein HD dampers would make another big difference I am sure.
