This aluminium lower brace is a tuning component made for the YR-X12 1/12 competition chassis. Machined from the supplied 2.0mm 70-75 duralumin plate, it increases lower-chassis rigidity while lowering the centre of gravity to sharpen handling precision.
The relatively thin profile keeps it compatible with narrow-diameter tyres commonly used on indoor carpet circuits, and its added traction tendency helps reduce high-sides on carpet. On very grippy layouts the plate dials back excessive steering bite, resulting in a more composed car through fast corners without major setup changes.
Fitting is a direct chassis replacement that alters front-to-rear flex balance; follow routine maintenance checks and verify screw torque after the first runs. Choose this plate when you need firmer lower chassis support or a subtle drop in centre of gravity for steadier lines.
