I have the Wilwood "Superlite" four piston calipers on (what I think is) a Granada NON VENTED 11" rotor (or was it 10.5)?
I'm using the Polymatrix "D" compound (with "A" compound being NASCAR specs, the disc rotors "glowing red" and STILL being able to stop).
This pad is "medium" heat range, stops GREAT when cold or moderatly hot, nice pedal feel, very predictable. Changing the calipers and pads made a HUGE difference in being able to more precisly control the brakeing (modulate them).
At an SCCA event the car will be "sitting" for some time and then BAM, your up and it's time to run on COLD brakes! There is no chance to "heat them up". My concern was a higher temp pad would not give me the precise braking modulation I want at lower temps?
At a road course event, running ten laps for instance, I got PLENTY of time to heat them up and HAVE to go with a higher temp pad!
Sounds like I need a couple of different compounds and will have to change out the pads as required.
You think a vented rotor would dissapate enough heat to allow for a "cold" compound in a ten lap race? I can only do 7 laps at full speed as it is now, braking late and hard (which is what I HAVE to do with a Porsche on my butt). It's a one mile track.
The killer is the "hair pin" at the end of the straight, THATS where my brakes die (120 mph down to about 25). I need to do that THREE more laps and I'll be a happy camper!
