All:
For those of you interested in upgrading your stock brake pads to something more suitable to the track, I see that Pagid now has front and rear pads available for purchase through Turner Motorsport (and possibly others):

The default material is Pagid RS29, a very common material in the endurance and club racing community. As race pads go, it's a good combination of friction level, modulation, pad life and rotor friendliness.
I already have a set on order and will post impressions after my next track event.
