Hi Ben,
I went for the KUMHO ECSTA XS ( KU36)......
I thought it looked like it would handle either street or track.
AND...they came in nice FAT sizes in the 17 inch .

Bob Jane had them here in Australia at $275-00 a tyre ( Fitted ) ...
(Strange !! it was the same price for the 255/17 fronts, as the 315/17 rears ?)
Cheers,
Warren.
