Well almost a year later and finally doing some things. It was about time to change brake pads so figured might as well do the lines as well....and the brake fluid, trans fluid, and diff fluid. I'll post more pics later but ended up going with Z1's Premium stainless brake lines, StopTech Street pads, Motul 5.1 brake fluid, Redline MT-85 trans fluid, and Redline 75w90 diff fluid.
While working on the brakes, one of the hard lines actually cracked and had to be replaced. It broke at the passenger front side at the angle where it passes through the metal fender well. I guess all the heat from the downpipe and the vibration at that point weakened it enough to where it broke while I was installing the steel lines. Didn't discover it till I was bleeding the brakes. I'm just glad it happened while on the jack stands and not while driving.
So we replaced the entire line and actually did a small reroute to take it further away from the downpipe and alleviate some stress. The line did well though, having lasted for over almost 6 years boosted. While we were at it I also said bye bye to the heat wrap and went for a full high temp ceramic coating to the downpipe and some other hot turbo pipes.
