Ultra Racing 4-point front lower brace – Lexus RX 300 (XU10) 3.0 V6 4WD 05-12
Ultra Racing’s 4-point front lower brace stiffens the lower front chassis structure by connecting key body or suspension mounting areas. Reducing flex gives the suspension a firmer base to work from.
The vehicle-specific steel brace works well alongside other chassis and suspension upgrades. It adds structural rigidity without replacing the suspension components themselves.
