So My saga continues. I go to clean up my torsion bars and find that one has ALLOT of rust pitting and the other has just one small rust spot.
So they have to be replaced right? I definitly have to replace the one that is pitting but aren't they matched? I guess after 30+ years they may not be any more? If I have to replace them what size is the best for a Street/ AX car NOT a daily driver? Thanks! |

The highest stress occurs on the largest diameter (surface) of the bar. Any pits means a broken bar waiting to happen. (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif)

Yes, I've seen it. It happens quite often, the car is usually drivable, just has a saggy front corner. |

usually they are coated in a heavy grease. i hope you note the "L" and "R' stamped into one end before you put them in.

I had one break once. Must have happened while it was parked cause when I walked out to get in it I noticed the right front was sitting very low. The drive to the shop was interesting. Felt like the road was covered with ice. If it had let go on a hard turn I believe it would have caused me to crash.

21mm bars on there way (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif)
I'm gonna have to look at matching the back with a slightly stiffer spring as well (IMG:http://www.914world.com/bbs2/html/emoticons/dry.gif) There the least aggresive and I shouldn't have to worry about being matched But may the teener is just sucking the money out of my bank account!!! |

See it all the time on bugs, torsion bars on rear of IRS cars, will droop to one side. I am certain handling would be spooky, with a broken one. You may like the handling with stiffer front, softer rear, but pay attention so you don't swap ends and back it into something

Do you think a 140# spring in back would be too much? I'm installing a stock front sway and DO NOT have a rear sway as of yet. |

Stiff front, soft rear sounds like understeer, not oversteer. Or as the good old boys say, push, not loose. |

Yep they do tend to break where they are rusty.
I also had one go recently, see the attached picture. The bar rubbed on the tube of the a arm, right were the rubbing and the rust was is where the bar broke so rust = bad (IMG:http://www.914world.com/bbs2/uploads/blog-1132394965.jpg) |

I borke one, drove 50 or 60 miles on it. Just tried to avoid the big pot holes. Having a front sway bar probably makes a difference (I had one), because you then retain some springing on the broken side.

Why? What's the advantage of a heavy torsion bar on a street car? |

I think he said it was an Autocross car. now ditch the rear bar and 200's for the springs. Koni sports and some sticky new Hoosiers. (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif) |

I would only use those for road racing...
For autox I would get a larger sway bar. |

Why?
Because I don't want to have to go back in there. I'm installing the stock bar for now to get it back out on the road and will start uning the suspension from there. My whole front end was shot and since a wanted to by new bars they were the least stiff of the upgraded bars that I could find. I should be able to work with then far into the future. |
