So I'm reading the SPC instructions and I'm pretty sure I'm thinking about it all backwards; when it says to "change positive camber" to set it this way versus the other. What the instructions don't say is that if you set it this way to adjust the positive camber is that you are not actually adding positive camber to cancel out the existing negative camber. At least, this is what I'm thinking in my head.

So, to confirm what I'm thinking in my head I'd like to present these pics :

Set it this way for adding positive camber to remove negative camber. In doing this the ball joint will be pushing closer to the middle of the car thus moving the connecting arm closer to the middle of the car and adding positive camber.



Set it this way to add negative camber thus pushing the top of the tire away from the middle of the car.



Option #1 is what I want to take my 2.5 degrees of negative camber and get it back to OE spec...correct?

Thx!

Here are the instructions if you would like to read it for yourself :

Looking at the pictures and the diagram took me a minute. Then I realized that the pictures are of the underside of the control arm and it's upside down from the instructions sheet.

Hold on...

You mention this but if you push the top of the tire away from the middle of the car, this is adding positive camber.

http://en.wikipedia.org/wiki/Camber_angle

If you do have negative camber, where the top of the tire is further towards the middle of the car than the bottom of the tire is, then you would do option #2. This is illustrated in the top picture of Figure 2 in the instruction sheet.

Ok, I'll try to make my wording a little better. To take me from 2.5 degrees negative camber to 1.0 degrees I will need for the offset of the ball joint itself set the entire ball joint closer to the middle of the car. Reason being is that the end result will pull the top part of the hub closer to the middle of the car as well thus adding positive camber. So I would need option #1 from the picture above. Am I thinking about think correctly?

So I watched a video online about another vehicle's SPC adjustable ball joint upper control arm and I'm confirming my thinking was correct. The offset of the ball joint itself needs to be closer to the middle of the car, versus the outside. This will add positive camber, thus moving my 2.5 degrees of current negative camber to a tire-friendly OE spec 1-1.2 degrees. Yay!

Now it's time to get the rear arms and get an alignment.

Let me know if your choice is correct. If you have a negative camber of 2.5 degrees and want to change it to a negative 1.0 degrees, it seems like you would want to have the ball joint further out (away from centerline), thus rotating the arm/hub.

As an example if you look at the front right arm, sitting in the driver's seat, as you push the ball away from centerline of the car, you rotate the arm/hub in a clockwise fashion. Does this make sense and help you out?

Did you have to do any grinding on the control arm to add positive camber?

loroko

I did it ,how the first photo , pushing it all the way out

Let's simplify this...

when installed, have the top nut loose so you can adjust it. If you push the top of the wheel in towards the car you get negative camber. If you pull the top of the wheel away from the car, you get positive camber.

So your first photo is positive camber and the second is for negative camber...mine are maxed out negative

To make it even more simple, let me just state it this way (now that I've had them on the car for 10k miles) :

Pic #1 : If you wish to add additional negative camber into your setup, use the ball joint this way.

Pic #2 (how I have mine right now) : If you wish to add positive camber into the setup to subtract away excesssive negative camber, use the ball joint this way. You WILL want to grint the lip off of the UCA.

I had to grind mine to add positive camber, after my aligment my camber was on .5 on each side. This is also lowered about 2.75" on BC coilovers.

How can you tell how far you need to go with the adjustment on these SPC ball joints?

Thank you sir. I already ordered and received them. I will probably have them installed tomorrow/

I would assume with an alignment.

As mentioned above you need to have the car aligned after you install these. I'm actually a firm beliver that any car should be aligned after you lower or raise it any amount.
