If you are going to stay with an expensive, high performance tire, the S03s are very good.
I have Toyo Proxes T1-S on the NSX. I will probably step up to something like an S03 in the near future. The Toyos are pretty good, but I think I can do better for that car. I would complain about the fact that I only got 8k on the rears, but that is what a lowered NSX with 3.5 degrees of negative camber will do to a set of tires. I will be changing my H&Rs to Eibachs to see if I can get that down to 1.5 or 2 degrees.
If I were you, I would get some Yokohama AVS ES 100s. They have 90% of the performance of the S03s, at half of the price or less. I got a set of 225/50/16s a few years ago for around $400 shipped.
They wear very well. I had about 25k on mine, including a few DEs, when I sold the Bimms, and they looked brand new.
Honestly, I don't think you need more than the AVS ES 100s on your 328. They were a perfect match for my modded 325.
