Need More Positive Camber
I'm sure that this will be an easy one for most of you but I'm stumped.
I restored my 77 Carrera 3.0L Euro and in the process of rebuilding the front end mounted early Turbo (year uncertain) A-Arms and not my originals. During the front alignment, we had to push out the struts all the way against the bodywork to get to 1/2 degree of negative camber. Prior to this, I never had problem with camber and body interferrences. So, before I rip and tear, I thought that I would get some advise from the group. Thank you in advance..... |

Are both sides equal? If not, the strut is likely bent.
So, what camber setting are you trying for. Most of us like negative camber. The more the better for a spirited driver.

Both sides are equal. Struts are the same one's that were on the car before the issue. Just no way they could have gotten damaged.
Trying to get back to original spec (0). What bothers me is that the struts were basically centered in the body openings prior. I am out of adjustment..... |

Well, maybe Turbo arms are longer. I always thought they were the same, except that the crossmember, chassis, and front bushing mounts were modified so that the A-arm axis is inclined in side view.

Well...only one way to find out, I guess. Will let you know in a few days. Thanks for the feedback... |

Ride height will have an effect. Did you lower the car at all when you did the swap?

No geometry changes to ride height due to parts but do have it dialed down a little lower than normal.

How low? Pictures? Sounds like you "built in" camber by doing that "ugly low front end thing"...don't worry or be upset, please, that's just my opinion. I stand by the old 3/4" to 1" diff., front fender lip relative to rear....
Edit: for general street use, the "0" you seek, with maybe -1 out back is perfect? Last edited by nesslar; 03-09-2011 at 06:20 PM.. |

"Ugly" well a bit harsh on Track Guys, no?
In any case, to each his own. When I lowered my car and replaced bushings, my passenger side strut was bent and I could not get enough positive camber to obtain .75 negative, it was pegged at 1.8 negative camber. Took it to Johnsons and had it fixed, all good now.

BTW, -.5 camber is just fine. In fact, very typical for a car at Euro height.

To be more specific, the Porsche Spec Book calls for 0 degrees for euro height and 0.5 degrees positive for US versions. 1/2 negative just means you are slightly lower than euro height.
Cheers, Joe |

Porsche only speced 0.5 positive since the front was so high they could not get zero. Positive camber is detrimental to both handling and tire wear.

Makes sense regarding lowering.
We'll raise the "ugly" (no offense taken) out of it and see where it leaves me. Thanks.... |
