my front fenders are 24 and 3/4'' from the ground and the rears are 25 and 1/4''

 

Those look like the Ichiba's, I like the design except for the 6 set screws, what a pia

 

I read that the spc gives a range of -1.5 to +3.5. Do the spacers give you +2.5 degrees camber?

 

I'm lowered a little over 1.5 inches. My front left camber is -1.25 and my front right camber is -1.66. So, there would be no reason for me to install the additional spacers?

 

The arms give you one full degree. The spacers give +2.0 degrees.

 

is that before or after the alignment?

 

After.

 

That's pretty good. The cross camber is more than i've seen on a G but it's not that bad at all. As long as the car doesnt pull, you'll be perfectly fine.

 

So there is no adjustment for camber?

 

If you've already maxed out the camber, no. You can add some negative camber to the left side to make it even with the right. But if it's not pulling, then there is no reason to do so.

If you leave it as is, i would flip your tires every 10k miles if they're directional. If they are assymetrical, you can just swap them side to side every 5k and get even wear.

 

Do you add negative camber by adjusting the tie rods?

I barely rotate my tires, but will start when I get my suspension STRAIGHTENED OUT.

 

No, tie rods adjust your TOE. You adjust camber by loosening the 27mm nut on top of the SPC A-arm, then you'll push it towards the center of the car just a tad, then tighten the nut back down. But that is going to mess up the toe so you'll need to get another alignment done. I would just leave it as is.
-GP-

 

How do you adjust camber without aftermarket A-Arms?

 

You dont. There is NO adjustment. Only the rear camber can be slightly adjusted from the factory via eccentric bolts in the sub-frame.


I got the impression that you already had the SPCs installed. If you dont, then you'll be fine with just the arms. No need for the spacers as that would put you in to positive camber numbers which is a big no no on any sports car.

 

Thanks for everyone's time in this thread, I am learning a lot!

You said you could adjust camber more negative to match the other side, how do you do that?
