Contrary to what seems to be the conventional wisdom, I have never found track pads to be lacking in cold bite. Quite the opposite, in fact. I have always found that track pads have noticeably stronger bite than my performance street pads. That includes driving to the track at the crack of dawn for November events when it was ~30F.
The problem is, usually that cold bite is from abrasive friction and it's hell on rotors, as compared to ablative friction from the transfer layer when things are hot.
Are these considered "track only" or can they be driven to and from the track? Would you recommend running ST47 front and rear? I have been looking at the Raybestos literature and it seems that they are sort of saying that the ST45 is recommended for the rear. If I remember correctly, about $230 for front and about $165 for the rear.
However, the Carbotech XP10 (front) / XP8 (rear) set up is almost exactly the same price.
I must admit, I was a little surprised at the price of all of these pads.
As for ST47's on the street, I've driven mine to track events 200 miles away with no problem except lots of dust. If it's going to be a couple weeks between track days and I expect to drive the car on the street, I will swap them back out for street oriented pads.
I would run something less aggressive on the rear, but that's just me.
$230 sounds excessive. I think I paid under $180 for my last set from Randall Race Parts.
