H&R OE Sport Springs Subaru WRX STI 04-07

Every spring produced by H&R comes from the H&R ISO 9001 certified engineering and manufacturing facility in Germany. All H&R springs are produced from a special 54SiCr6 spring steel, which has strength rated at 290,000 psi resulting in unrivaled tensile strength and resiliency.

At H&R product design and development is of the highest importance. All H&R springs are "cold" wound on specially designed CNC machinery and then time-tempered to re-align the molecular structure of the steel to ensure quality and durability.

All springs are shot-peened to increase the service life of each spring by more than 200%. Each spring is then sent through the H&R exclusive "SuperBlok" system, which cycles each spring to ensure that sagging will never occur. Lastly, the H&R special powder coating process coats each spring with a flexible and durable finish that is highly resistant to corrosion, chips, and scratches. At H&R we care about quality - the whole production process, from start to finish, is done in-house to ensure the most consistent, highest quality product possible.

For some, the idea of upgrading a vehicle with performance suspension sounds appealing, but a noticeably lower ride height and slightly firmer spring rates don't. H&R OE Sport Springs are the solution. OE Sport Springs lower the vehicle subtly, yielding a slicker, more aggressive stance without noticeably altering appearance. The end result is a car that is more controlled and balanced, yet has the uncompromised ride characteristics you're accustomed to.
