As far as I can see there's no stock/factory rear toe adjustment on the CL9? unless i'm missing something. I assume one has to go and buy the Hardrace kit(4 arms total), as soon as you use an adjustable upper control arm in the rear you can see the toe is out of spec.

 

The rear control arm has an eccentric bolt on the body side for adjusting toe.

 

I saw that once I decided to remove all the multi-link arms, wouldn't have provided adequate toe adjustment at my current ride height. Decided to get the 4pc toe/lateral arm set from hard race and the rear upper control arm aka camber kit as well.
