When precise changes are needed, these RACEOPT 3mm aluminium shims deliver straightforward adjustments. The set includes eight 0.5mm pieces to help you get suspension and chassis spacing right.
Made from 7075 aluminium, the shims keep added weight low while standing up to repeated use. The blue anodized coating helps resist wear and keeps the parts looking tidy after track sessions.
Perfect for altering suspension geometry, shimming gear mesh or correcting minor misalignments in the chassis, these washers provide a reliable, repeatable shim option for hobbyists.
