Having thrashed many pad brands around the track in various WRX, I can confirm that Ferodo DS2500 are a great pad - probably to much for a lightweight car though? DS2000 might be a nicer choice, good cold bite and you really know when they get up in temp

Gentle as on discs with all the good points being better than the M1144s and the older Ultimates
Yellow stuff and Ultimates are not the same (I should say the old Ultimates having not used the new ones), IME Ultimates are disc hungry and filthy on heavier cars, Green Stuff is probably a closer pad in terms of how it feels - the issues with the Greens was the first batch(es) fell apart, long since fixed. Yellows are great pads (big capacity though), if the newer Ultimates are considered similar then I'll humbly eat my words
5.1 all the way, just takes a little more punishment between changes.
If you are anywhere in the country, Racebrakes is the place to go, Steve is super helpful
