After further research, I'm now leaning toward Bridgstone Potenza S-03 over Michelin Pilot Sport. All others have fallen off the list. Any feedback out there on these two tires?

More data just for your reference. I redid my suspension/wheels about 10 yrs ago, going to the setup illustrated in my gallery at: <http://www.classiczcars.com/photopost/showphoto.php?photo=2337&size=big&password=&sort=2&thecat=500>. These are 15x7, zero offset Panasport rims, with Good Year GS-C tires, 225/50x15. We trimmed out the fill rubber at the top of the shock towers to lower the profile without reducing suspension travel. I have Eibach progressive resistance springs with KYB gas shocks. The only mods were to roll the metal lip on the rear fenders to eliminate tire rub. But now I'm redoing it again. This time 16x8 Panasport C8's (4-3/4" backspace), and I'm considering Bridgestone Potenza S-03s size 245/45x16. New shocks and coilovers will take up less space on the inside thus the positive offset. Food for thought...

I'm looking for recommendations for the best ultra-performance tires folks have found out there. I have a 1972 240z with numerous performance upgrades, including 16x8 Panasport racing rims (4-3/4 backset). I'm looking at size 245/45ZR16. This is a weekend-only vehicle so these tires will be used exclusively in dry conditions as I will rarely if ever be driving the car in the rain or on wet roads. I'm strongly considering Michelin Pilot Sport, Dunlop SP Sport 9000, Bridgestone Potenza S-03, Goodyear Eagle F1, and Pirelli PZero. Thanks in advance for any ideas. J. Zorzy

I need to replace my alternator. I have a 1972 240z built 6/72. According to my ZCD, the correct part number should be 23100-P0102(R - all now are rebuilt), which indicates a 12V-50A Hitachi LT150-05B. However, Courtesy Nissan shipped me a P0103R (Hitachi LT150-10R). To further confuse things, I am told the part number I should look for is 23100-U5800R or -H6206R. Exactly which is correct??!
