I wouldn't recommend the red stuff for street, mine were crap from cold... The yellowstuff are OK, EBC are by no means the best quality of pad, but I found the Yellowstuff better than the standard pad.
I've tried drilled/slotted discs on the standard caliper and found no difference to the solid OEM disc, they look nicer behind the wheel but make a racket.
Most of the decent pads aren't street legal, DS2500 / M1144s etc.
