BMR 15-17 S550 Mustang Drag Version Lowering Springs (Set Of 4) - Red

Looking for a set of tried and true lowering springs? 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 750 degrees F, 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 our spring manufacturing process. Every spring is computer tested as the last step. 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. This allows BMR to offer a LIFETIME WARRANTY against spring sag. Order your set of BMR suspension springs from us here at Need 4 Speed Motorsports.
