SHOfun 93:
Are they better than PFCs?
According to Carbotech, yes, of course, but we'd need to compare specs to be sure.
From the Carbotech site, for the Panther:
Friction coefficient: 0.5-0.55
operating range: ambient temp to 900F
Does anyone have real specs for PFCM pads? Does PFC even make a 598 pad? Or are they still only making the smaller 601 for this 96+ application. Last time I checked, I got: 1996 FORD TAURUS SHO - V8 ENGINE - DISC/DISC CARBON METALLIC® STREET PAD - FRONT - 0601.20 (601 is the smaller 94/95 size)
If you want to compare race pads, the Carbotech pads are:
CARBOTECH PANTHER XP
operating temperature range 250F to 1350F coefficient of friction 0.58-0.60
CARBOTECH PANTHER PLUS
operating temperature range 150F to 1250F coefficient of friction 0.54-0.56
CARBOTECH PANTHER
operating temperature range 150F to 1100F
coefficient of friction 0.52-0.54
Carbotech Bobcat (included for comparison)
coefficient of friction 0.5-0.55
operating temperature range ambient temp to 900F
CARBOTECH SUPER STREET-F (included for comparison)
coefficient of friction 0.42
operating temperature range 75F to 800F
I've run the F-street and Panther, and the Panther has a LOT more bite than the F-street, and the Bobcat has similar specs to the (dusty) Panther.
If you want to compare other compounds ..
Wilwood:
Poly A (track pad)
coefficient of friction of 0.55-0.7
operating temperature range 200F to 1300F+
Poly D (track pad, but this is what I use on the street - the T/Tan's are just not enough for me)
coefficient of friction of 0.4-0.5
operating temperature range 0F to 800F
Poly T (street pad)
coefficient of friction of 0.35-.45
operating temperature range 0F to 700F
As you can see, the Panther have a race-level grip with a CF in the 0.5 range, and a near-race level temperature tolerance up to 900F, all while still being a street pad. If you need to get the rotors glowing, swap in the P+ that has a higher tolerance (and wash off the dust ...)
