Hyperco's optimum body diameter (OBD) design concept is a proven performance advantage and is relied upon by championship winning teams in several forms of racing. And now, that performance advantage is available for 1/4 Midget competition!
With design input from the top quarter midget chassis builders and race teams, Hyperco has developed spring designs that meet the specific requirements of modern quarter midget racing.
OBD Hypercoils feature a unique design concept - Hyperco adjusts the body diameter of the spring relative to the end coils. The OBD design technique enables Hyperco to take full advantage of its extensive range of ultra-high tensile material by optimizing the applied stress through adjusting the spring's body diameter.
OBD quarter midget springs are available in spring rate increments without tolerance overlap to ensure predictable suspension tuning for a wide range of track conditions.
The results are incredible and a proven winner!
