The Kyosho UMW508C 4.8mm High Mount Ball Stud Set is a handy upgrade for Ultima owners wanting more suspension adjustment. This set of four studs increases the ball to seat clearance by 2mm versus stock studs, opening up more tuning choices.
A raised ball stud alters the mechanical leverage on your suspension arms, which can sharpen turn-in and stabilize mid corner behaviour. This change is especially useful for drivers tailoring handling for different track surfaces.
Listed as an optional front upgrade for the Altima RB5, these studs are intended for Ultima-compatible setups that use 4.8mm fittings. They give you a simple way to refine front end response without complex parts changes.
