Precision laser-cut from 6061-T6 aluminum and anodized for durability, these shims are used to adjust camber by changing length of your Porsche OEM or similarly configured lower control arm (such as these RSS units). Thickness in millimeters is silk screened on each shim for easy sorting.

One degree of negative camber is approx. 10mm shim.
