I sort of liked those KDW's when I had them on my car. I think the pair Dan owned were the ones he got from my FN's IIRC.

They were decent, but nothing I would feel completely comfortable in. I would break them loose really easily upfront, but this was way back when. But for an occasional autocross and daily driver they would do good since they were quiet and comfortable compared to other tires I have owned. Aren't they crazy overpriced still?

So far Invo > RE070 > KDW of the sets I have owned.

EDIT: I used to call them the fire tread tires when I first got them.
