for me Carbotech XP10 are one of the best you can get for the front, Ferodo DS2500 will be my second. I never tried the DS3000 so i cannot compare.
On a different note, My 310mm disks are 28mm wide.
I to would say the xp10 carbotechs are a great pad!
I dout i will ever use a different pad.
I had oillecasts old evo3 calipers and clio 280mm disc setup and did a track day at brands, and for such a cheap setup it really amazed me.
No sign of fade at all and good pedal feel,if anything it just highlighted that i need uprated brakes on the back now.
The xp8s maybe better for a road car but tbh the xp10s where fine from cold as well,and the hotter they got the better they were.
These are very dusty pads though so you will have to keep on top of cleaning your wheels.
Have a look at some of the reviews on the mlr.
