I got grooved front and rear discs from mtech for 104. I also got yellow stuff pads as i mentioned previously. I have fitted them too. I also got new rear bearings (fag) from central auto supplies for 10 each side. They come with the bearing grease and was a full kit.
Also you should be able to reuse the abs ring (i sprayed plenty of wd40 and gently prised it off and fitted then i aint had a issue with abs either. Why do you want to replace the abd sensor? If its playing up then fair if its not then dont waste your money mate.
