I ran S-03's on the old RX7. Definately an excellent tire choice for dry/wet on the street/trackdays (for my p/w ratio,). A good tire is one that you can predct exactly how it will react if you change conditions (like dry pavement to wet pavement). Optimal is to find a tire that does not make you change your driving style when traction conditions change. Inspires confidence, and confidence helps you go faster.
