With over 50 years of spring design and manufacturing expertise, our S2 Sport Lowering Springs are engineered to improve handling while maintaining safety and ride quality.
B&G lowering springs are wound from high tensile Chromium-Silicone wire purchased from Europe’s premium mines. The lowering springs are cold wound on CNC coilers; heat treated and shot peened for longevity; and finished with phosphate treatment and a baked on resin powder coating for a hard corrosion resistant shell.
By redesigning the O.E. Spring and the lowering the center of gravity from 0.5-2.5 inches (depending on vehicle and application) our Technicians dramatically improve your vehicles performance and appearance. Incorporating a progressive rate design Allow B&G lowering Springs to offer higher rates for improved road hold, while maintaining a comfortable ride
- Lowering Spring applications from 0.5 – 2.5 inches
- Progressive Spring rate design to maintain ride quality while improving road feel and handling
- Cold wound from high tensile chromium silicone wire and individually super blocked and computer tested against tight tolerances
- ISO9001, QS1400, and TUV Certified
- Limited Lifetime Warranty

Thank you for your support.

These springs are more like a "dual rate" spring made popular by Eibach, vs the progressive spring mentioned. But I hope they are not as shown in the picture.
What you want is more widely spaced springs vs the close spaced springs. The springs on the right are about correct in this regard. The spring rate is inversly-proportional to the number of "active" coils. More coils, softer rate.
So as the spring is compressed to the installed "weight bearing" condition, all the coils should be active.
When you take a corner hard, the outer springs compress. For the pictured spring on the right, the two closely spaced coils compress to coilbind, leaving about 3 active springs. This is the "stiff" condition of the dual rate spring, and is 1.67 times the original soft rate. Based on shape, looks like a rear spring.
For the left spring in the picture, the soft rate is based in the 6.5 active springs. But when compressed in a corner, or when loaded up with girthy guys, most of the coils compress to coil bind, leaving just 2 active springs. This stiff rate is 3.25 times the initial soft rate.
