OfficinaRC Black Brass Smart Shim 3x9x1 mm - (8) OFC-BBSS-3910

If you have ever lost a race because your suspension felt inconsistent lap after lap, chances are your shims were the problem. The OfficinaRC Black Brass Smart Shim in 3x9x1mm solves that quietly and completely.

Machined from high density brass, these shims bring real weight exactly where you need it without adding bulk to the wrong places. The black finish is not just cosmetic. It resists corrosion and keeps your build looking clean after hours of track time. Each pack includes 8 shims so you have enough to set up a full car and keep spares on hand for race day adjustments.

At 3x9x1mm these fit a wide range of 1/10 touring car and pan car platforms and are a favourite among competitive racers who tune suspension geometry with precision. Whether you are dialling in roll centre height, adjusting ride height, or fine tuning your diff stack, these shims give you consistent results every time you go back to a known setup.

OfficinaRC builds for racers who take their equipment seriously. These shims are a small part that makes a big difference.
