The XRAY 323550 Composite Rear Shock Tower Adjusting Shim gives model racers a straightforward way to alter shock placement. Constructed from resilient composite material, it supports alternative mounting positions to change handling feel.
Repositioning shocks rearward shifts weight transfer and response, which can help reduce snap oversteer and smooth corner entries. The composite part is durable enough for repeated tuning without adding needless mass.
