Well, if the max 0.75 deg of camber (

Since I don't want to go beyond a stock level prep with a DD, I'm looking at a street tire stock type setup. Ideally, I'll get stock size Pilot Super Sports for the stock wheels for DD and wet autox plus something more aggressive on lightweight stock size wheels for dry autox. Right now, I'm thinking 225/45 Yok AD08's. Most tests put these just a bit behind the R-S3's for ultimate dry grip, but they reportedly have stiffer sidewalls and don't need as much camber as the R-S3's. I might even try them for everything at first (DD+wet/dry autox) since they are reportedly pretty good in the rain.
Evil: I hadn't heard anything about the new Z1 SS until you mentioned it - any more concrete info than the stuff here:
