It is no secret that H&R builds some of the best made and highest performing springs in the industry, designed and manufactured to be stronger, more resilient and more durable than the competition. All H&R springs are crafted from a proprietary (hf) 54SiCr6 spring steel to ensure premium quality and performance. For maximum durability as well as longevity, all H&R springs are precision shot-peened prior to release, a special process developed to increase spring life by more than 200%. H&R develops designs and tests all of their products in-house and each spring is quality tested before leaving H&R’s ISO9001 certified production facility in Germany.
It’s not hard to determine why Sport Springs are H&R’s best selling spring. H&R Sport Springs offer an enhanced look by reducing your vehicles fender gap, resulting in an aggressive performance look. The stiffer springs will increase cornering stability, reduce body roll and provide a much more exciting driving experience in your 07-11 Mazdaspeed3.
