These OfficinaRC Brass Smart Shims are the kind of small upgrade that makes a real difference on race day. Measuring 3x9mm and sold in a pack of eight, they give you the precision weight placement and consistent shimming you need to dial in your setup without second-guessing yourself.

Machined from quality brass, they add low and centralized ballast right where your chassis needs it most. Whether you are fine-tuning a touring car, a pan car, or a buggy, these shims fit seamlessly into your build and hold their position lap after lap. Racers who care about repeatable setups know that the details matter, and these deliver exactly that.
