Is the bolt supposed to be bent like this?

I would say that flipping the bar over...I mean take the bar out, put the side that is currently on the drivers side on the passengers side..
This will change the angle of the part that is hitting your trunk floor. Rich |

It appears from the photos that the through bolt supporting the shock and sway bar may be under quite a high bending load. Are there any instances of failure of this bolt?
The springs carry the weight of the car. Maybe this is really not that much of a load? (IMG:http://www.914world.com/bbs2/html/emoticons/idea.gif) |

the springs carry the weight of the car, and damper forces may be more than 3X the spring load (which is why those rear bolts - Porsche calls them 'pins' - are so beefy...
but the rear ARB is pretty wimpy on most cars - and those long spindly lever arms have their own deflections that reduce the real spring load. and remember - both lever arms move together in jounce and rebound, and the ARB mount (that Allen capscrew) sees shear load only in one-wheel jounce -- and roll - which 914's don't really do that much of in the back anyway - especially with uprated springs... |

your not the first person to ask that (paul was I think) but apparently it's not a problem. mine is an extreme example, because with our weird shocks we even run an aluminum spacer on that bolt... yet no failure, concerns, bending, or problems. I copied my set up from AJRS who runs many BIG slick shod cars with similar set ups and 300+ hp brant Attached thumbnail(s)

Thanks for all the input guys. I have learned more about rear sway bars than I expected. I think I will keep my set up as is for the first track weekend. The new drop links have already changed the angle of attack and I want to see if that changed the feel and response. One thing at a time.
BTW - when I first installed the new parts I did it with the ass of the car in the air. When I dropped it, the joint filpped and bound up. I reset it the 2nd time with the car on the ground. I then jacked it up 6 times to see if I would again have the problem of it flipping. So far it all seems good to go. |
