Anodized Aluminum Porsche GT3 Control Arm Shims

Porsche GT3 And Similar Two-Piece Lower Control Arms

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 approximately a 5mm shim.

Competition Motorsport Shims Available in the Following Sizes:

• 1 mm
• 3 mm
• 5 mm

Package Savings:

• Enthusiast (two of each shim) save 10%

These fit all two-piece Porsche lower control arms (except 991 GT3/GT3RS rear and 992 front and rear, which use a different shim shape). Shims are priced individually (other than packages). They are typically used in pairs or in multiple-shim combinations. Also fits 981 and 718 Cayman models.
