OfficinaRC Black Brass Smart Shim 3x9x2 mm - (8) OFC-BBSS-3920

If you've spent any time fine-tuning a touring car or pan car setup, you already know how much a proper shim stack matters. The OfficinaRC Black Brass Smart Shim in 3x9x2mm is one of those small parts that quietly does a big job. Brass gives you the weight and density that aluminum simply can't match, and when you're dialing in suspension geometry or diff height, that precision is everything.

This pack comes with 8 shims, which means you have enough to work across multiple contact points without running back to your parts bin mid-build. The black finish isn't just for looks either. It helps with corrosion resistance and makes it easier to spot the shim during assembly, which anyone who has ever lost a 3mm shim on a carpet track will genuinely appreciate.

OfficinaRC builds these to tight tolerances, so you're not guessing at stack height. Whether you're setting up for a club race or a national event, consistency in your shim thickness translates directly to consistency on track.

Compatible with most 1/10 and 1/12 scale applications where a 3x9x2mm shim is called for. Always verify against your kit manual or build sheet before ordering.
