The Beatrush PPF Power Plant Frame Brace eliminates rear axle tramp on Mazda MX-5s. The soft OEM bushes allow the differential to twist on its mounts. With repeated abuse, this twisting can cause the PPF to break where the differential is bolted to it. Solid polyurethane or aluminium bushes hold the differential firmly in place. However, the forces are transferred to the differential’s arm which in turn can snap.
The Beatrush PPF Power Plant Frame brace prevents the differential from twisting by connecting the PPF to the subframe. The forces are transmitted to the subframe instead, reducing the fatigue on the differential’s arms. The Beatrush PPF Brace is therefore ideally suited to prolong the life of the differential and the PPF on track, drift and high-horsepower cars.
Please note does not fit 89-93 Mazda MX-5s. If you are unsure, contact us for more information.
