VVV, I should have said "which is why it used to be that many SS lines are not DOT approved." 5 years ago or so, it was hard to find DOT approved lines, it seems that it has become common now though, youre right. As far as every year on the non-DOT approved ones, well that's what the racers do with them, and they tell me not to would be a safety hazard even on a road car. I'm not trying to say that SS lines are worse, but that one shouldn't assume they are better just because they are SS. I.E. don't buy cheap SS lines to replace good rubber lines.
