Spiegler lines are the highest quality available, and they are what we use in our complete AP Racing Competition Brake Kits. Spiegler's owner is a German engineer who owns and operates the business in Ohio. The fittings are from Switzerland, are far nicer than the competition, they have swivel fittings which takes tension out of the lines, and they have a tighter weave with a sheath over them. They are slightly more expensive than other options, but still cheaper than a set of good race pads. Spiegler also has incredibly stringent testing procedures for their lines, and they are DOT compliant. There's therefore no reason to skimp on lines. They are a critical brake component, and there are none nicer than the Spiegler ones!
