I use my focus in sprints and we have a list of tyres to choose from which excludes trackday tyres ,toyo 888's etc.

These are excellent, and all the front runners have gone on to them from toyo t1r's. A mate in an Integra type r beat me into second with these in the wet, so you're getting the best of both worlds.

Can't comment on longevity, since most of the cars either don't run on the road, or have spare race wheels.
