Tire Recommendation Sought: DE/Non-Suicidal Street 17"

[larrybard]

Seems as if every time I have been reasonably happy with a tire, or sought to try a particular recommended one, I find it is apparently no longer made in the size I need (e.g., Toyo R888, Goodrich G-Force R1, Kumho Ecsta MX).  I currently drive a '95 993.  (205/50/17, 255/40/17)  I was very happy with Michelin Pilot Sport Cups, but the PSCs are no longer available in my size.  Last time I had Kumhos (don't recall which model), but they too are no longer available.

My son and I (both "blue" students) tried the Bridgestone Potenza RE-11 at Watkins Glen, as an attempt to balance track performance with street suitability (including the ability to survive driving to and from the track in the rain, if encountered).  We felt that they weren't as sticky on the track as their predecessors.

My desire is to get something stickier, yet street legal.  I would strongly prefer not to make the jump to track slicks that are not street legal.  I am willing to sacrifice economy (price and wear) for track performance, but am not willing to buy anything that feels downright dangerous on the street in heavy rain.

Suggestions would be greatly appreciated.

Thanks,
Larry
