Brass chassis brace is used to adjust the chassis flex. The brass brace has the same features as the alu chassis brace but at the same time it works also as an additional weight as it is 15g heavier and is positioned in absolute center of the chassis. Recommended for high to very-high traction conditions as the weight is positioned more in the rear of the car. There are 4 flex adjustment possibilities – Soft, Medium, Stiff and Extra stiff.
