Thanks guys, your input is very much appreciated.
I spoke to Courtaney and they said they have the copper pipes made up to include in the kits due to customer feedback. They were very helpful but didn't say who their supplier was, lol, as they must have the spec for a Mk4 hatch.
My mate has had VXR front brakes fitted to his Mk5 and done the braided lines at the same time. He has kindly offered to measure his - and was the one that told me the trailing section is the same on the Mk4 and Mk5. From that I'll be able to get a pair made up 🙂.
However, if anyone comes across any I'd be grateful for a link...... 😉
Cheers,
Dave
