R1WURKS Aluminum Shim Set (5pcs) for V21-S

If you are serious about dialing in your V21-S, the R1WURKS Aluminum Shim Set is one of those small upgrades that makes a genuinely noticeable difference on the track. Precision shimming is one of the most overlooked aspects of competitive RC setup, and having the right material matters more than most racers realize. These shims are machined from quality aluminum, giving you consistent thickness, reliable durability, and a weight profile that plastic simply cannot match at this level of racing.

The set includes five pieces, so you have enough to address multiple contact points across your drivetrain or suspension geometry in a single session. Whether you are fine tuning bearing preload, adjusting diff height, or correcting lateral play in your axles, these shims give you the control to get it right without compromise. R1WURKS builds components for racers who expect precision, and this shim set is no exception.

Fits the V21-S platform and is compatible with standard RC10 based pan car configurations where R1WURKS components are used. If you are building a race ready setup from the ground up or refreshing a competitive car mid season, keeping a set of these on hand is simply good practice.
