just need to jack car up onto axle stands, after removing 1 wheel at a time, remove the 2 rubber tops on back of caliper, need 7mm allen key to undo the 2 holding bolts, take off caliper, making sure you do not strain flexi hose, and remove old pads, undo the 2 holding bolts to remove rest of caliper body, should be hex nuts so only the right size spanner needed, undo grub screw from old disk, and tap disk off with small hammer, clean area and calipers refit in reverse order, making sure you clean new disk with brake cleaner to remove any factory grease/oil. should take 30-40 mins a side if you have not done this before. just remember you will need to put new brake pads on with new disks.when driving no heavy braking so as to allow new disks/pads to bed in.
hope it helps
