You've combined the names of two tires.

There is an "ultra high performance summer" tire made by BFG called the g-Force T/A KDW 2. In 205/50-15 it costs $97 a piece from tirerack.com, plus shipping and mounting. It looks like this:



There is also a "high performance all season" tire made by BFG called the Traction T/A. It is not available in 205/50-15, however is available in 195/55-15. In that size it costs $78 per tire plus shipping and mounting. It looks like this:



In terms of performance, the KDW 2 does pretty well but it's hardly a match for something like the Kumho MX or Falken Azenis. The Traction T/A is an all season tire which means even less dry grip.
