With the Ed 30 Std Pescara they would need a spacer. The rim shown is a BBS VZ 8.0J with an ET44 offset. 3mm clearance at the caliper face, so no spacers needed.
The disc is actually taller than the Std Gti 312mm disc, so it takes the centre line of the disc closer to the track rod end.
The Standard Ed 30 rim is really restrictive, being 7.5" wide.
