The owner really liked the new power and performance of his ‘Bird, but he soon found the limitations of the leaf-spring rear suspension design.
Increased power translated into decreased traction and more wheel hop, so he elected to have the V8 Speed & Resto Shop install a BMR torque arm rear suspension kit on the car, as well as 4-wheel Baer brakes, ZE Forged wheels, Goodyear Eagle F1 tires, and a necessary exhaust re-work to clear the new rear suspension.
The BMR rear suspension kit completely replaces the leaf springs with a pair of bolt in the lower control arms. They attached to the front leaf spring pockets, and to brackets that bolt to the original leaf spring mounts under the rear axle housing.
