How can I get less negative camber on the front?

[rnln]

I don't understand why you guys can have -0.5 degree camber with ride height at 25.5" front and 25" rear, without serious modification?

I have my front left at 25.75" and front right at 25.5". I grinded the strut mounts holes on the tower to expand them to the side to have more positive camber. Still, the max I can do is -1.2, -1.3 degrees on the front.

I like the look of the straight wheels, least negative camber, beside tires wear reason. If I can have 0 to -0.5 degree on the front, that'll be great. Anyone know if there is any oher way to have less negative camber?

I ran 1.0 front and 1.5 rear when my car was stock three years ago and i had even tire wear with 16 inch tires.
If i remember,i had 1/16 toe in all around and max 5.9 castor ... hardly even noticeable ...

Cheers !

Right now, I can only have around 1.3 degrees front, can't get any less than that. For this, I have to have at least close to 2 degrees rear. I afraid that will wear tires more on the inside, and I don't prefer the look of 1+ degree negative camber. I am hoping to get less negative camber, if I can.
I know if I raise the car higher, I can get a little less but it's already at 25 3/4" (to the fender lips) on the front.

ok, with all the plus and minus signs, and then not, you just confused me. Do you want the top of the tires to lean inwards towards the body ( negative camber), or lean outwards away from the body, ( positive camber ) ? I'm thinking you want as close to zero as possible? or maybe -.5 ?

[rnln]

as close to 0 (zero) as possible, toward the side, but the best I can get is -1.3 degrees without driver sitting in.

Sounds like you might have bent spindles.

1.3 should be near the most negative you can achieve, not the least.

[DRACO A5OG]

Nope, PO dumped it so results are severe neg camber.

Chuck, what is the symptom of bent spindle? How can I test? Thanks.

Lanly, moving the top of the shock toward the middle line of the car = increase negative camber. Moving it toward the sides of the car (out ward) = increase positive camber. This is what I want.

This could also be caused by the strut towers rolling in. I'm new here so I don't have a feel for how strong the strut towers are on a 911. Have you measured the distance between known points on your strut towers and compared them to factory data or a known good car?

will try, thanks.

You can verify if your struts are bent with a protractor. 11 degrees is the angle you want to see between the strut and the face of the rotor.

I solved this issue with my car by using a strut brace that allowed me to jack the strut towers apart.

[rattlsnak]

Is it noticeable? or are you going by readout specs from a front end machine? I highly doubt both sides are bent exactly the same. I think i would try a different location/machine first before i go any further.

[Trackrash]

I was able to get about a 1 degree less camber on each side of my car. However, my car is a '71, without the extra reinforcements the newer cars have. Be careful if you do this as you can get a noticeable gap between the fenders and the front hood.

Ironically I now use the strut brace in the opposite way. I track the car and want more negative camber now!

Have you checked your wheel bearings for tightness? Sounds strange, I know, but loose wheel bearings will cause the wheels to lean in at the top. Also if the shocks are loose or bent it could cause your problem.

Symptom #1 is too much negative camber.

Symptom #2 is a small bulge in the strut body, just above the spindle collar.

As above the correct angle is 11 degrees, but it is very hard to measure this.

While it is unlikely that both are bent the same amount, it is also entirely possible.

Bent spindles are surprisingly common. We see a large number of struts since we perform spindle raising and other strut modifications. Probably 1/3 of the used struts that come in the door are bent.

Trackrash,
Huh? You meant you just literally push the strut's towers apart (chassis) to minimize negative camber? If so, I will get strut brace for sure. Do you remember how much (degrees) the strut brace helps?
I check bearing, tighten it often, and just did again today.

rattlsnak,
Draco and I level the ground carefully so the car is on level ground. We tried to adjust the driver side then used digital leveler to measure camber. We also spent time to test run the wheel lips to make sure which area of the wheel's lip is not true, even on very tiny spots.

Thanks everyone, thanks Chuck.

On my car I was able to get about a degree more positive on each side. IIRC I was able to push them apart about 1/2" total.
