Sorry to bring back a relatively dead thread, but I have been searching for recommendations on what to do for brake lines.
I have been much happier with my previous vehicles using SS lines over stock rubber lines.
The main lines for the c6 z06 are the Stoptech and Goodridge G stops from my research, I know there are other suppliers such as VSS, Mallet, etc. and I would rather go with Mallet, but they have yet to answer me about buying their product. At this point I'd rather buy a known supplier in the Stoptechs or the Goodridge lines.
People have commented that Goodridge tests their lines to 12,000psi, but everything that they state says they only test to 3,000 psi. Whereas Stoptech tests their lines to 4,500 psi and they come with a coating to protect the SS braid from abrasion.
Which lines do you all prefer if you have experience with one or both?
(the car is a weekend toy primarily used for track days/hpde and autocross)
Thanks

Both of them are phenomenal and they both will work. But me personally am more partial to Goodridge lines for one reason and one reason only. All they make is hydraulic hoses.

My SS lines are Stoptech and I've had good luck with them. Regardless of what lines you get, expect that you may have to overtighten the connections to the car's hard lines. GM way over torque's these connections from the factory and virtually everyone has found the threads distorted. Some have had to use thread chasers. I was lucky as three of the four line went in OK with no over tightening. The left rear had very minor weep with normal tightening (flair wrench used), I tightened it more, still weep. Tightened it even more and it has been weep-free since.

12,000psi Really? That's an insane pressure for a brake hose. Not picking brands or sides but I don't think I'd be fitting a hose set to my car that has been intentionally stressed to that degree.
At the end of the day most companies may stress test their products to such high numbers but I'd not bank on each and every finished line produced it chocked up and done to that. That just doesn't happen, regardless of what companies tell you. You'd clearly see pre installed seating in the flare end or chassis end if it had to be tightened to a hardline end for testing.
There was some debate over the quality of ss flex line used in kits some years ago. Weave or braid size, and the thickness of the teflon liner, jacketed or not.... Even the discussion of why crimp ends are the only legal part for a "DOT compliant" hose (there's no DOT Approved hose) yet race cars with cutter ends are not DOT compliant But you can race them at 200mph all day! The results of that discussion were rather inconclusive with a lot of "this is better than that" and noted issues, failures, frays, leaks etc. There was no final verdict that only brand A is worth using.
All of them will increase pedal feel and firmness. The older the rubber it replaces the better. None of them have shown to reduce stopping distance of any significant value. Unless you quantify the time it takes to firm up. Nearly all today are jacketed and the less fittings the less likely a leak point. Incorrect fittings or incorrect installation can lead to rubbing and leaks. And no ss line should be installed and considered to be a life long part.
Just my .02
