How to install seat harness

[Chixican]

A lot depends on the type of harness you have. For instance I was looking at a Schroth harness because it has passed US DOT regulations for street use if mounted properly. The angle of the harness depends on the harness type, I would go back to the manufacture and ask what they suggest. As you can see below, for that particular harness they don't suggest anything more than 45 degrees, however in a different section of their site for a NASCAR style harness they suggested only 10 degrees.

"The Rallye 3 is the choice restraint for anyone who's car will not work with a Rallye 4. This would be the case if your rear seat was too close to the front seats for optimum geometry. In any harness, you absolutely do not want to have a tailstrap that angles down more than 45 degrees from a line parallel to the ground. Past this angle, the shoulder belts will not work the way they are designed to. In some cases, the Rallye 3 will offer the right solution."
