Hi,
I am looking for a new set of tires for my cough... 79 Firebird... cough. The car is putting around 400 hp at the wheels. For several reasons I cannot leave 15". I want this thing to handle and brake as good as possible

-15"
-235 to 255 wide (needs to go on a 15x8" wheel)
-aspect ratio between 50 and 60
-needs to be street legal
-speed rating at least H, better V
-Very important is dry and wet BRAKING and HANDLING.
-I do not care AT ALL about snow or "M&S" rating, I am looking for a summer tire
-I do not care AT ALL about wear. If the tires are shot after 10000 or 15000 mls that is totally fine.

Is there anything like that around? The closest I could find were Yokohama Y352, but I cannot find anyone in the US who can sell me some of those.

Firestone Firehawk Indy500 seems to be OK (read other post), but they only have an "S" rating. This car will very likely end up on the Autobahn by the end of this year. Any ideas?

I am Ok with paying some extra for extra wishes.
