Performance Lowering Springs Set
with Minimal Drop
for Ford Mustang 5.0L GT 2015-23 & 2024+

Manufactured by BMR Suspension | Part #SP763R

There is nothing like the aggressive look of a car with the right stance.

Over time, stock springs sag, get rusty, and simply wear out. BMR believes the right springs go beyond looks... your S550 & S650 needs to perform too! All BMR springs are manufactured from chrome silicon high-tensile spring wire, and are cold wound on a CNC coiling machine. The CNC coiling head can adjust the spring diameter in real time to ensure that every spring is exactly the same. This guarantees that your right spring matches your left spring. Every BMR spring is compressed solid at the factory, not once, but twice. This gives the spring its permanent set, and guarantees no sag. BMR springs are stress-relieved at 399°C, ensuring most stresses induced during the winding process are eliminated. All springs are then shot-peened to eliminate residual surface stresses. Many spring manufacturers skip this step, but BMR insists on this operation as part of their spring manufacturing process. Every spring is computer tested as the last step, not just a sample from each batch. Each spring is loaded in the spring tester at the factory, then compressed and the CNC load cell measures the force for a variety of spring lengths.

Blending aesthetics and performance, BMR has designed the SP763 for the power adder crowd who want great all-around performance without worrying about the front-end sitting too low. These springs are designed for vehicles with the extra front-end weight of a supercharger or turbocharger kit. These lowering springs feature a fine-tuned spring rate (170 lb/inch or 19.21N-m front, 740 lb/inch or 83.61N-m rear) to give you great performance and a smooth ride. The linear spring rate offers plenty of support, keeping the body flat and level, while remaining soft enough for a comfortable ride on any road.
