GTI rear discs

[Leebob]

Because you would have to remove the old bearings from the discs to re-fit to the new discs and would probably damage them in the process, new bearings are fairly cheap and mk3's can be quite hard on rear bearings if the pre-load isn't set correctly so all in all its better to change the disc/pads/bearings in one hit for peace of mind.

Good to know,il bear this in mind if I ever do mine.

Do'nt forget your abs rings if you have abs as not all new discs come with them

Take the old ones off and re-use.
