The Yokomo B12-302CSB Brass Center Stiffener is an effective upgrade piece for the BD12 family. Swapping the standard graphite stiffener for this brass part increases central mass by about 25 grams, which helps to cut down on roll and gives a more composed handling characteristic.
Concentrating weight in the centre smooths out weight transfer and makes the chassis less prone to sudden oversteer or nose lift. Drivers will notice steadier mid-corner balance and clearer feedback when fine tuning setup for lap consistency.
A compact, mechanical method to alter chassis balance, this brass stiffener suits club racers and weekend tuners looking for a steadier BD12 platform.
