My SSR: "Babe" '06 Pacific Blue/Chrome/6pd #22407, born 10/14/'05, and #21393, died 2/16/'07.
Even for my spare!
As a hard driving 6-speed owner who lost his first SSR to the all-too-common slipping in the wet, you will love the bite and grip of the KDW2s. Available at Sears... and my RoadHazzard has paid for itself, too.
Note that the BF Goodrich "KDW" and "KDW2" are NOT the same!
I foudn when researching tires for the SSR about a year ago that, for one thing, the KDW2 for the rear is notably larger diameter than the KDW - despite the fact that both were speced at exactly the same size.
I don't know what other difference ebtween them might exist.
For me, the larger diameter of the KDW2 was a no-go, as I did not want to "change my gearing", which a larger tire would definitely do. The difference was, as I recall, at least 1/2 inch, which is about 2%. Some people wouldn't care, but I very much did.
The KDWs I got were terrific tires. Greg Ducato, who drove my supercharged SSR both before and after the change to the KDWs, remarked on how much better the KDWs hooked up, and I confirmed that over the next several months.

I just tested brand new KDWs in the rain on my SSR this weekend.
There were 2 roads near my house that I would spin my GYs if not careful...well I spun the KDWs as well....the grip seems to be somewhat better than the GYs, but it looks like they won't solve all my rear end woes.

True, KDW and KDW2 are different, and are currently not speced the same, either. Both are ultra-high performance summer tires, but the 2's have higher performance numbers (hook harder, too), are have superior hydroplaning resistance (8.4 to 8.0, TireRack). The KDW is .3" taller than the RS-A, and the KDW2 is 1.3" taller (1.1" by my non-load measuring).
RS-As are a high performance all-weather tire. It has a hydroplaning resistance of 5.6, and offer middle-to-fair performance in their catagory of all weather. The only thing it offers over the KDW/KDW2 is fair snow ability to the KDW/KDW2 N/A snow ability (none).
Changing your gearing 2% is not a performance loss if you consider overall improved performance. You can hit the KDW2s harder and faster in almost every performance catagory. If you worry about our loose rear-end, the extra grip is just a bonus. Plus, they wear evenly, and last longer.
But I can loose my KDW2s in the wet, too, and I will not be able to drive in the snow. Oh, well.
