I haven't been able to find and Camber bolts yet for th ct200h (just a simple cam bolt, but needs to be able to be torqued to 177ft lbs as per the manual)
Lexus does offer different sized bolts, and using a combination of them one can get different camber settings.
There is a chart in the manual which you need to follow in order to get the desired camber, but that is for a stock ride height CT200.
It looks like using part number 90105-17018 bolts (referred to as *f in the chart) on both top and bottom of the knuckle, one can get -1.50 to -1.25 degrees of camber. Again this is on stock ride height.
The bolts are only $5 each so a combination of them may be used to get the right results,,even if you have to order multiple bolts it would be under $50 or so.
Here on Sewell, the chart on top left has somewhat of a description of the available bolts.
The one they are referring to as Type C, appears to be the one referred to as f* in our OEM service manual. (Has two dots on the right side of the bolt head, and one dot on the left)
