If you get cupra r, golf mk4, Octavia vrs front wheel drive rear calipers then they will just bolt on. Reason why I had to get spacers is that my ones are quattro versions. The spacer I have in the picture will only allow me to put on the 256mm vented discs not anything bigger. I was trying to source the right spacer to allow bigger discs because it is possible but have not had any luck.
