I have hit a curb with both left wheels. Today, I took my Z to the alignment shop to see if anything was knocked out of alignment. Shop corrected few of the settings. But, they can't correct the rear left toe with the stock toe bolts.
It does not make sense to me that the rear left wheel toe was 0.02in before and 0.24" after alignment. How can toe be that much worse after alignment?

 

Well, first a bit of curiousity... are you running adjustable camber arms? Interesting that both F&R camber were adjusted back closer to center of range and have always been under the impression that only toe could be adjusted.

Which... could explain why toe increased. Any adjustment to the main angles, camber, front caster, toe, have an effect on the other two. I suppose that could have affected the rear camber too, based on this; but 0.5 degrees on LR? Seems like a lot of camber reduction from a toe increase. Hmmm...

But whack things do happen when they get hit by those loose, feral curbs running amok and such.

 

My tires sizes are 275/35/18 front and 295/35/18 rear. I am on my second set of tires. First set only lasted 15k miles. Rears had excessive wear on the inside and one of the front tires had a nail too close to the side wall. At that point, I replaced all four tires and installed SPL adjustable rear camber arms. All other suspension components are stock.

Front camber only changed by up to 0.1 degrees. Tech said that is within their machines measuring repeatability.

Now that I understand how toe and camber adjustments work together, I am still surprised that rear toe got worse by 0.22" for a 0.5 degree camber adjustment.

 

I am interested in buying SPL rear mid links to get more toe adjustment capability. Do mid links come with compatible springs? If not, which springs do I need to buy? I would like to keep using the factory shocks for now.
