Default my first odd vision~

Maybe is an old issue but i found out my wheels are not exactly the center from the fender, comparing left side and right side....it's like the wheel on one side is closer to fender (NOT the gap height).

I have been told from porsche guy due to previous year 964 and 993 production are half by machinery and half by man-power that causes this problem around.

Have anyone notice?

Let me know, thks!

Same on mine, but only the rears. I can see it if I stand behind the car, lining up with the side. Left side is out more then the right, not protruding, still under the fender.

I am sure I once read this somewhere. Streather's book? I think it suggested the jig was off or something? My memory of it is fuzzy but I think they are like that.

This is a known issue with some cars and not indicative that the car was previously in an accident. And why aftermarket rims with wide tires and aggressive offsets should ideally be test-fitted before purchase. There is one Rennlister here who needed a 10mm or 12mm spacer (IIRC) on one side of his rears for both sides to have the same fender clearance.

We weren't referring to the offset (which generally refers to wheels) but that the suspension/frame is not completely aligned with the body. But yours is the first time I've heard about different spacing in the front...what I've seen or heard about has only been with regards to the rear.

My car is exactly the same from side to side front & rear so I don't see what you are seeing but it could be that your front suspension has two different negative camber angles.

IE: One degree of negative camber moves the outside top of the wheel closer to the fender edge where as two degrees moves it away.

Check the camber on each side and if they are the same, that's not it and I have no other ideas as to why you see it on your car.

You may want to check your control arm. During a race couple of years ago I was hit in the left front, breaking the strut brackets. Found a replacement strut, and we rebuilt the car. When we tried to check the toe, found it was off and we adjusted via the tie rods so that both wheels were straight. But...apparently the control arm was slightly bent, and no the car had 1" longer wheelbase on one side versus the other. Similar to you, the wheel was no longer centered in the fender opening. Ran the car next day, but held back a bit to be safe; was fine for the whole race. Later replaced the control arm and you could see the bend when compared to the replacement.

Not sure if 911's have similar control arm layout.

My 84 3.2 had this problem – one rear sticking out a little more than the other.
