woohaa there all caps 
The PS2's were designed specifically by Michelin for the IS-F. I don't know for sure why they don't put them on all F's but I would assumte the reason they don't stock all PS2's is they want to give individuals a chance to choose their tire and so they need more then one option. Plus, aren't the Bridgestones a tad cheaper then the PS2's? That would be another reason why they would offer more then one tire.
I am burning through a set of Bridgestones and will have the PS2's put on next. Why are they so much better if you mind me asking? Just because of the sticker compound?
