BMR 79-04 Ford Mustang (Ex. 99-04 Mustang Cobras w/ IRS) 1in Drop Rear Lowering Springs - Red

Starting with chrome silicon high-tensile spring wire, these BMR lowering springs are cold wound on a CNC coiling machine. This advanced coiling process allows for real-time adjustment of the spring diameter, ensuring that each spring is manufactured to be an exact match for its counterpart on the other side of the car. This attention to detail means your Mustang's rear end will sit evenly.

BMR doesn't stop there. Each spring is compressed solid twice at the factory to permanently set its shape and prevent sagging over time. They're then stress-relieved at 750 degrees F to remove winding-induced stresses and shot-peened to eliminate surface stresses, a step many manufacturers skip. Finally, every single spring is computer tested for load and spring rate at various lengths, guaranteeing consistent performance. These SP029 springs are designed to lower the rear of your 1979-2004 Ford Mustang by 1 inch, offering a fine-tuned linear spring rate that supports the body in corners for better handling while still providing a comfortable ride on the street. The red powdercoat finish helps them look good for a long time.
