As Andrew has said you can't go past that QFM pads, I'm using the A1RM pads, they have unbelievable cold bite (I seriously couldn't believe it), and i have used them at Mallala and pulling low 1:20's and for 15 minutes and never had any fade. Also done 2 modern Reg' events and i still have another 2 days left in the pads, that's with a few hills runs as well.
They have a 1/2 price rears deal (through GSR RallySport, who's a trader on here) as well and i got free postage as well so that's front and rear 780 degree pads for $190 posted.
