so all in all, what's the weight addition for this bar over stock? Was going to go with race seats and harnesses for weight savings, but if this weighs more, is it worth it?

Weight reduction alone is a silly reason to do it though, IMO. A good harness weighs almost as much as the stock belt, for example. So you could get some light(er) "sport seats" that still allow you to use the stock belt, and like you said, use the lighter stock brace back there rather than a heavy duty steel harness bar. |

For what it's worth, the bar is VERY light.
That said, IMO, seats and harnesses should be viewed as safety items, not simply weight savings. The bar is in the same boat. |

The factory bar is aluminum. The Robispec bar is steel. Think he was talking about the factory bar.

Stock bar is very light. 3" diameter steel is not. I would like to know what thickness/alloy they're using. |

Based on this I'd just get a mild steel in cold roll since its stronger but make sure its DOM or ERW since are cars are heavy and its 3", not 2" which cages are.

The location of that stock horizontal bar (that this one replaces?) is a very poor one for mounting harnesses anyways. It puts too much rearward length on the belts between the seat-back and the mounting point, which allows them to stretch more than they're designed to in a wreck. It *is* definitely a step up from putting harnesses on the stock bar itself though, because that thing isn't nearly strong enough.

3" .120 wall DOM would be what I'd make this bar of if I were going to do it. Gonna be heavy tho. |

I'd guess they're more in the .08 or even .06 range. |

This is for harness mounting, which I think .06 is woefully inadequate for. |
