Most sporting set of tires in the stock size is either the Falkens mentioned or the Sumitomos. I would say the Michelin Pilots but they are twice the price of any of the others and I can't imagine they would be twice as good. Everything else available in either the stock size or plus one (235s) are a step or two downgrade, but probably still some decent tires in the Dunlops, Yokohamas. The only reason to consider the downgrade tires is if you really, really want the raised white letters which do IMO look good on the tall 60 sidewalls particularly if your car is already a dark color. Here is what is available.

*I believe this is the same as the Discount Tire house brand Road Hugger. I bought a supra with these on it once - complained loudly around corners. I am leaning heavily toward the Sumitomos for my next set.
