The 912's are more of an all rounder, bit harder compound and longer lasting (I hope) than the 452's.
I changed from 452's to 912's for economic reasons and they're good enough for my driving style, such as it is, and I've not noticed any real difference in performance having come from the FK's, not that I drive like a loon, but the fairly fast & twisty commute to & from work hasn't thrown up any handling surprises.
