H&R Sport Springs are the #1 selling performance street springs for BMW automobiles - and for good reason!
One of the first steps in suspension tuning is replacing your vehicle's stock springs, and H&R Sport Springs are the go-to choice for those in the know. Choosing H&R means you get superb ride comfort and increased driving confidence, thanks to the lower center of gravity and reduced body roll that gives you better handling and chassis balance. Plus, you get an aggressive but driveway-friendly stance for better aesthetics.
The progressive spring rates of H&R Sports are increased by 10-20% over stock, and they're designed to provide superb ride quality and comfort during normal driving conditions, yet they stiffen up for proper chassis composure when the roads get twisty! As an added benefit, they lower wind-resistance profile will make the vehicle more streamlined and improve your gas mileage.
H&R Springs are manufactured to be strong, resilient, and more durable than other automotive coil springs, and they won't settle or sag. All H&R springs are crafted from a special 54SiCr6 spring steel to ensure premium quality and performance, and they're shot-peened to increase life by more than 200%. All production is completed by H&R in-house so they can ensure the highest quality for their products. Each spring is 100% tested before leaving the ISO9001-certified production facility in Germany.
