EBC yellowstuff are made from horse hair and camel spit
Ferrodo DS3000 very aggressive on the disc
Ferrodo DS2500 are not man enough for anything other than road use
XP8`s ok for road use
XP10`s are superb but squealy
XP12`s are even better given the weight of the car
Carbonetic R - not tried but get a great review so are deffo on the list when its time for new disc AND pads
In your position with standard oem discs I would put in a second hand set of oem pads. The oem discs you have will struggle to cope with the extra heat the after market pads will cause and thus kill them fairly quickly. All the pads listed above need to be run with a non drilled disc.
