cool.
ds3000 good feel ,consistant, used on v8 brutes. the discs crack before they break up.
ds2500 pretty average not very bity. and crumble with hard use. (since 3000 came along) but once warm ok.
ebc green. garbage and extreem taperd ware.
sbc ceramic carbon. awsome street/track pad. long lasting and dont overheat the disc. my pic for steet/track
sbc duel carbon. very good aswell. more track orientated. long lasting and take an awfull lot of heat. (targa favorite)
performance friction carbon metalic.
omg insane pad. so easy to use and instant pedal responce. my pic of the list. but due to the fact that they work so well you cant tell your overheating the discs. cos they feel the same from warm to a orange hot disc. (as used in most top level motorsport. nascar,v8 supercars etc etc)
bendix ultimate,ferodo formula,metal kings etc etc. pretty crap and good for going up to the shops.
i haved used all these pads in my gtr with 355mm rotors and brembo f40's (38,44mm pistons) and im hard on brakes. once you get good brakes you seem to explore there limmits hehe
