I have used almost any pad thatīs on the market for the 4pot impreza caliper,
mintex 1144,1155, carbonelorraine, DS2500
and have used both greenstuff, redstuff and yellowstuff before,
but the problem is that its some years ago, and the compound is not the same anymore, so cant really compare.
I had just payed for a set of PF z-rated for my front Brembo, and a set of yellowstuff for the rear, as they had gotten good reviews, when EBC wanted some review on the Bluestuff pad,
So did not try this setup.
I had on my way home from work worked the brakes a bit harder today, and the griplevel is going up for sure,
the reardisc on my Type R is the early type, that is not eacy avalible, so had to use the ones allready there( there is a fear lip), so it will take a will for the rear to bed in,
When i lock the diff under braking, to transfer som more to the rear, there is a huge improvment over the oe brembo pads ,and standard rear pad.
and yes the are better when abit more heat is into the pads.
I had a few 160km/t to 60km/t braking sessions today, and they are really great, and look forward to the "real" test at the ring
