I'm definitely doing this, what was exact ask/specs you used while having the lines made? (want to duplicate entire set-up) Thanks for sharing this, looks awesome! big fan of the Porsche logo being left on, throw back to my MK3 days
I asked for base model Macan fittings on the caliper end of the line, and Golf mk7 Golf R on the hard line side.
I don't have the technical specs for the fittings required. B8 A4/S4, base Macan, 3.0T Q5 all use the same fitting on the caliper end per ECS's site. Most VAG cars share the same fitting on the hardline side.
If your source of SS lines says they can't make Macan lines, try the other models above and see if you get more results. They just might not realize they're the same. Length should be 24" per carbonfold's friend's and my experience.
