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's suspension believes the right springs go beyond looks your 2015-2023 S550 Mustang and 2024 S650 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 SP080 for the street performance crowd who want to use their cars in a variety of application. These springs will lower your Mustang, 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's suspension!

Sticks very good. Did a lot of things front and rear on my Polaris side by side. Seams much quieter and had enough leftover to do another one.

Reduce sound vibrations in your car! Works great! This is not sound proofing, it is Sound Deadening
Size: 10 sqft, Size: 10 sqft
This Butyl rubber sound proofing kit includes nine 15 1/2" x 10" peel and stick panels. It really is a lot of coverage, but I still will need a second box to finish my car doors. The instructions are easy to follow and the only tools you need are scissors or a knife and a small roller, but you could get away with using a pan scraper to press the product down. You may need paper and a pen to make a template for certain areas, though. I used some cardboard from my recycle bin to cut template pieces for the hard to see areas inside my doors. This is fairly easy to install once you have it cut into pieces, just peel the backing off and stick it on. Be very careful to not let it stick to itself, as it will be nearly impossible to separate. This stuff is crazy sticky! No worries about it coming off once you've stuck it to your car. To add this to your car doors, you will have to remove the interior door panels, but there are lots of YouTube videos on how to do this on all sorts of cars. Note that is is sound deadening material - Not sound proofing! You do not need to cover 100% of the car with this. The material is designed to stop noise from resonating through metals, so even one piece of this on a large area of sheet metal will stop the sound vibrations quite a bit. I am covering about 80% of my car doors with it, then planning to put sound proofing on top of it. This sound deadening material needs to come in contact with the metal surfaces to stop the sound vibrations, so it would not be very helpful to put it on top of sound proofing material. Also note that the installation requires temperatures above 50° Fahrenheit. Since it is winter, I've warmed up my garage while working on this project. In low temps, the sticky stuff would probably have trouble adhering to cold metals. So far I have tested just having it on my front doors, but I already can hear the difference. This soundproofing definitely does minimize road noise and external sounds from getting inside your car. It also stops music vibrations, so my radio now sounds clearer than it did before. I don't plan to pull out my vehicle carpet to install on the floor, but I would imagine that if I did it would greatly reduce the road noise even more. Definitely five stars on this product!
