The racer asked
3 mm upper arm schims
Miles, So Dialed's RC setup AI
On the Serpent Viper 990 Evo, 3 mm is the kit-default setting for the front caster upper-arm shims. That setting affects caster and kick-up; it is a different adjustment from the front upper-arm FF/FR shims, which set camber gain and roll center.
If you mean the caster shims, start at 3 mm as the kit setup. The setup information confirms what the setting changes, but doesn’t specify a handling direction for moving the shim amount. If you mean the FF/FR upper-arm shims, the kit defaults are 0.5 mm at each position.
