I don't think they made German TUV-compliant then either.  I've never considered them necessary.Your link also supports the rest of my comment:"Here's the thing, though: Since stainless-steel lines don't bulge as they age, and since the inner Teflon lining is hidden behind the braid, there's no easy way to inspect the lines for warning signs of imminent failure.This is no big deal on a race car, since the lines are (or should be) replaced at least once a season. On a street car, where most people are likely to let YEARS go by without even looking at their lines, it can be an issue."And:"If you do decide to put stainless-steel lines on your car, you need to be aware of a few things:1. When you install them, you must make SURE that they can't kink, twist, or stretch under any combination of wheel droop, bump, or (for the front wheels) steer.2. The stainless-steel outer braid will cut through anything against which it rubs, so you have to make sure that the lines don't rub back and forth over anything important.3. Stainless steel lines have been known to fail when dirt gets between the outer braid and the Teflon lining... As the braid moves back and forth, the dirt abrades the Teflon and can make it rupture. If you look at stainless-steel lines on motorcycles, you'll see that many of them are encased in plastic tubing, apparently in an effort to eliminate this problem. The tubing also helps considerably with the abrasion issue mentioned above."They look cool, but I just think they are potentially more trouble than they are worth.  YMMV.</blockquote>
