Yes they do. But you may have problems getting a disc to work depending on what year car the brakes are from.
Up to 1995 the VR6 had 280mm brakes. The calipers and carriers bolt on and you use a G60 Corrado disc.
Post 1995 they had 288mm brakes. The caliper and carrier will bolt on but I don't think there is any disc that is a direct fit.
