Thanks for all the input folks,

I just got back from my local tire guy, he said the fronts were in pretty good shape(pilot sport), but it would cost almost as much to put 2 new Mich sports on the rear as it would be to get 4 new Sumitomo HTR Z III. He also said with 4 new the ride would be better than 2new/2 45% fronts. He originally recommended General UHPs

. I felt for $100 more the sumitomo's were much better.
So I ordered the Sumitomo HTR Z III 18's. I will post a review after a few thousand miles and let you all know. If they are as good as everybody says then they are definately a great/cheaper alternative to the high dollar tires.
Mikeoh, I was looking at the f1 asyms, but they were about $300 more.
