This slim graphite narrow upper brace is an accessory for the 1/12 Yokomo R12c3.1 chassis and is intended for use with friction-type roll dampers. It occupies the upper brace location to modify chassis flex while fitting the R12c3.1 geometry.
Fitting is straightforward using the existing upper brace mounting points on the R12c3.1, and the part is designed to accept the same hardware positions as the factory brace so no chassis alterations are expected for compatible R12c3.1 rigs.
As an adjustable tuning piece, the graphite brace redistributes load between links and dampers, offering a different flex character that can be tuned with friction roll dampers to influence roll control and overall balance in 1/12 racing environments.
