Well...got this far. IRS all installed except for hard brake lines. The manual does not say how to rout the hard line between the left and right flex lines. I am hoping someone can post photos of how they did it. With the flex line terminations at the 2x3 s tube near the shock mount it looks lilke the hard line should just go across to the other side just under the trunk floor. The distance between the flex mounts is about 33 inches now. The brakes lines in the kit are 60 inches long. I guess I need to buy a 36 inch length? Seems silly to use 60 inches and just coil it up. Any ideas?
Thank you for any help you can provide.
Jeff

Pictures of the rear brake lines from my Mk4 build with IRS. Where you do the crossover is going to be influenced by where you put the tabs for the flex connectors to the calipers. You can see that in my pics too. I made my own lines and flared to length. You should be able to make something work with standard lengths. But I sure wouldn't coil a 60 inch line down to 33 inches. Ugh.
