I have the Generals on my 2000 Boxster. They are pretty good. I can take a 90° turn off a hiway road onto another hiway at 55mph, 60 mph is the edge of traction for a 320 treadwear tire. Spins out at 65mph.
Being picky I wish the sidewalls were a little stiffer. The ride is plusher than the Sumitomo HTR(another not bank breaking option) in my opinion.
