standard pads produce loads of dust........
get some K-Tec Kevlar or EBC Green Stuff
ive currently got the K-Tec Kevlar on mine, same setup as you, RT with 16v setup, and they work straight from cold, a lot better than original pads, and half the brake dust or less, plus there bloody cheap
the K-Tec Kevlar pads are standard EBC pads.......there bloody good
