Yeah they are . Are you sure the pads and discs need changing on the 172 cup you've looked at ? The rear pads are only 11mm new including the backing plate , 4.6mm minimum thickness . The rear discs are 8mm new and 7mm minimum thickness . Also they have the bearings already pressed in and the abs rings which you won't need as the cup doesn't have abs . You can just leave the rings on , it doesn't matter .
