I keep hearing guys getting the Michelin Pilot Sports. Same size in the rear, but they don't make the 265x40x17 for the fronts. However, they do make a 275x35x17 that fits perfectly. Also, the Michelin Sport provides a rim protector. On light contact with a curb, it could save a wheel.
Visit The Tire Rack's website. They have specs, prices, and tire road test ratings. The Bridgestone S-O3 Pole Position would be another great choice, but the last I heard, the biggest size for the rear is 285x35x18. They will have the 295 size soon. The fronts come in the stock size of 265x40x17. Also, you might consider the S-02 Pole position for the rear, as it comes in the stock size. The pro's at The Tire Rack can give you good advise.
The only problem might be in slightly different tread patterns....
HTH,
