Yep, I have them in 215-45-15. They're awesome. A real step up from the Yoko A509s I had (well, still have, they're sitting in the garage).
They have very high limits, have very readable breakaway (ie, you can feel when you're at the limits of adhesion, and it creeps up slowly, rather than coming upon you all at once).
They don't squeal much, and they're good in the rain too. The only thing they suck in is cold temps or snow, but that's to be expected, as they're summer tires.
They've been replaced by the softer-sidewalled T1-S, so you can get a great deal on the Pluses, as tire sellers will want to get rid of their old stock.
