      Description

      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 Suspension believes the right springs go beyond looks—your 1979-2004 Mustang 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 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—every spring, 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. This allows BMR to offer a LIFETIME WARRANTY against spring sag.Blending aesthetics and performance, BMR has designed the SP029 for the street performance crowd who want to use their cars in a variety of application. These springs will drop the rear of your 1979-2004 Ford Mustang 1-inch, and feature a fine-tuned spring rate to give you great handling and a smooth ride. The linear spring rate offers plenty of support, keeping the body flat and level in the corners, while remaining soft enough for a comfortable ride on any road. When performance and looks are a must, rely on BMR Suspension!BMR Suspensions SP029 lowering springs are available in red powdercoat for long-lasting good looks. Installation time is about 2-3 hours.

      Suspension components are key to making sure your car is riding smoothly on or off the road. With upgraded suspension components, you can unlock the full potential of your vehicles performance.

      Lowering springs are a cost effective way of lowering your vehicle. Lowering springs are designed to maintain most of your car factory suspension travel while gaining a 15% increase in spring rate. If you are looking to maintain or improve ride quality while also lowering your car, we recommend coilovers first, but if your are on a budget, you can't go wrong with a set of lowering springs.

      When BMR Suspension began back in 1998, it was difficult for performance automotive enthusiasts to find suspension products that had an innovative design and quality construction at an affordable price. BMR turned this market void into a business philosophy, and has been serving our customer's needs ever since. Currently offering chassis, suspension, and drivetrain products for 22 different vehicles, BMR is the leading suspension manufacturer in many of the market segments that it serves.

      Whether you are interested in street performance, hardcore drag racing, or handling applications, BMR Suspension has the products that you need. Proudly made in the U.S.A. in a manufacturing facility near Tampa, Florida, American workers cut, bend, notch, drill, and mill components from American-made DOM and chrome-moly steel. Then, every product is fixture-welded to maintain consistent quality. Workers bead-blast parts and then powdercoat them using BMR's in-house powdercoating line. Finished parts are then assembled and packaged in the assembly department. By manufacturing every product in house, BMR can control the quality at every stage of the manufacturing process.

      BMR Suspension products fit and work so well because they are street driven and track tested on BMR project vehicles. Past project cars include a 2005 Mustang drag car, a 2005 Mustang street car, a 2004 GTO, and a 1994 Camaro. BMR's current project vehicles include a 2016 Camaro, three 2015 Mustang GTs, a 2011 Mustang GT, a 2010 Camaro, and a 1969 Camaro. As if that were not enough, BMR also has a 2009 G8 GT, a 2008 Trailblazer SS,a 2003 Mach 1 Mustang, a 2000 Grand Prix GTP, a 1998 Camaro, a 1990 Mustang LX, a 1971 Camaro, a 1970 Chevelle, a 1967 Chevelle, and a 1968 GTO. But it is more than just great vehicles-virtually every BMR employee is a racer or hot rodder, as well. This love of racing is demonstrated everyday in BMR's customer service, design innovation, and manufacturing quality.

      By continuing to push the envelope in product design innovation and manufacturing technology, you can be sure that BMR Suspension will continue to offer the most innovative, quality-oriented, affordable suspension products available. When performance is a must, rely on BMR Suspension!

      Just what I needed.

      Wanted to level my 2010 and these did the trick. Took me about two hours to get on, and that was that. Car is sitting on 305/35/19 in the rear and 285/35/19 in the front. No rubbing or scrubbing.

      Too much of a drop. Installed and on the ground looks great, but this still managed to drop the suspension too far. Snapped the left axle on the first hard pull with a little squat. Highly recommend maintaining stock height to avoid this iussue.

      Good springs. A little soft.

      I bought these to replace a set of Eibach sportlines (1.7" drop in front. 1.8" drop in rear) that were too low for my taste. While the rear springs were perfect, and raised the back end approximately 5/8", the fronts have actually made the front end sit even lower. The fronts also feel considerably softer than the Eibachs.

      a lot lower than I imagined!

      Great quality product! It is hard to find info for convertibles so this review is specific to that body style. I purchased the 1.25 inch bmr drop springs and combined them with koni strt shocks and struts. Package looks good just a lot lower than I imagined it would be. Evens out the convertible nicely with just a little rake keeping the back end a little higher than the front.

      Looks great but not for me!

      Looks amazing! Ride is decent for the amount of drop. Lower than I want so I will be changing the setup, the fronts rub … not sure if it’s the wheel and tire setup or just too low.

      BMR Handling springs

      The springs make the ride height perfect for me especially with 20s! Very good ride even though it’s significantly stiffer than my non-pp1 GT was originally. Easy install too! 2-2.5 hours
