Hobbyists aiming for a firmer BD12 setup can fit the Yokomo B12-002AU US Spec Aluminum Main Chassis to reduce flex and sharpen handling. Its construction favours high-traction venues where a stable chassis helps maintain consistent lap times.
The B12-002AU is engineered to sit lower in the chassis stack, which helps prevent high sides on rapid direction changes and gives the driver steadier control coming out of bends.
This aluminium main plate is compatible with MSR-010A, MSR-BD12A and MSR-BD12 models, offering a straightforward upgrade path for racers running BD12 platforms.
The Yokomo B12-002AU suits drivers who want a tougher base for tuning on high-grip layouts without altering basic geometry.
