is there any resource/listing showing the the c o f for different brake pads ?

i want to find out for

hawk ceramic
hawk hp+
project mu NR
cobalt gt sport

 

Try posting in the road race forum.

 

keep in mind that COF is not really a good way to look at brake pads. there's a lot more to how a pad works than a simple straight number. (sort of like looking at peak hp and not looking at the torque curve)

I don't have numbers but here are some details from my personal experience...

Hawk HPS - my current street pad, smooth initial bite, low noise, really suck on track (fade bad when pushed hard)

Hawk HP+ - ok track pad (could get them to fade with street tires) ok on street (louder then the HPS and more dust but still ok)

Carbotech AX6 - very similar to the HP+

Carbotech XP8 - my current autocross pad, amazing fade resistance, initial bite is really aggressive for the street, tended to cause people getting close to rear ending me even when I was light on the pedal.
perfect pad for 1-2 lap high speed autocross sessions on street tires. With R-compound tires or more than 2 lap I'd bump to XP10, or even XP12 if you are a more experienced driver. (or have ABS)

 

thanks for your informative reply

c o f figure is just small part of my pad choice decision and just curiuos

ive ruled out hp+ as driven friends car with these on street and initial bite was too much, they chewed through discs and squeel constantly (my pad choice is for daily driver with lot of agressive braking and 3 maybe 4 track events per year), have to say though that they were superb on track though

im currently running project mu b force which im very happy with and meet all my requirements, im just concerned they they may not hold up on track (im a novice) although my b force were also very good on track and never faded although it felt after several laps like they they close to limit so im thinking of going for the b spec (jap equivalent with 500oC rating rather than 400 oC of b force)

then theres the the mu NR but i think these may be overkill for my requirements

carbotech are not well known in u.k but im impressed by what ive read over the years with them as well as cobalt although even their minimal pad may be more than i need
