Look no further - so I went with the falken FK510s after extensive research into finding the ideal tyre to replace the god awful run flats from factory - as the FK510s have a superior sidewall construction they provide the support of the run flats without the harsh, alloy cracking downfalls.
In terms of grip, wet or dry, excellent, I was running in the 500bhp category and struggled to make the rear slip when new.
Bad points - life expectancy isn't great, but not the tyres fault, fronts will last for many many thousand miles but with my sprirted driving, the rears will last around 12 months with every day use, although fully legal tread, I did notice some slip starting to occur at about 60-75% through its life.
With that said, I wouldn't buy any other tyre for cars designed with run flats....
