CMS Alignment Camber Shims for Porsche Two-Piece LCA

These shims are used to adjust camber by changing lower control arm (LCA) length.  Thickness in mm is clearly marked on each shim for easy sorting. 
One degree of negative camber = about 10mm of shims. 

Available in the following sizes:

  • 1mm
  • 3mm
  • 5mm
These fit all two-piece Porsche lower control arms (except 991 GT3/GT3RS rear, which use a different shim shape).
