I used to drive alot with a guy who ran those tires on his E30 (Spiff for those of you who remember him). He seemed to like the grip they had, but ran through them very fast. At the time I was running the same Yokohoma AVS ES 100 that I still run (well different set) and love the grip level in wet and dry. I think they are very similar compounds as both my Spiff and I ran through our tires in around 5k miles.
So enjoy them while they last
