Not sure if its only the PSS you need but these might just do the trick..

They are a great price for sure. Not sure if my expectations might demand more than 5mm of tread. Brilliant tyre though.
I have -2.85 degrees of camber which could see them off and effectively waste them without sufficient track days.
I could have that all wrong though....
