I say go out and try out the PSS on the apex wheels first
No...I didn't word that very well, I've abandoned the 7" wheels and will run my current Apex setup and see how they do. I scored on the tires ($400 for all four with 9/32" tread left) so they'll have been pretty economical if I get a few track days out of them and a few thousand miles on the road. I was just suprised that the consensus was that the race compounds weren't the better choice despite the smaller size. Frankly it's much easier to run one set as was said...I'm all for it if there's nothing to be gained.
