These shims fit 06-19 C6 Z06 & ZR1 and C7 Corvettes with aluminum frames and are used to shim the rear upper control arm mounting for camber adjustments. This kit includes 4 shims each of 1/4", 1/8", 1/16", and 1/32" thicknesses.
Each shim is CNC cut from aircraft grade aluminum alloy and anodized for corrosion resistance. The one-piece shim design is easier to deal with when making quick camber adjustments at an event and they don't require completely removing the control arm bolts to make adjustments.
