The stiffness spring rate of any single spring can be sligthely different even if all springs are made from the same wire rod with the same coil number.
In the “M-Chassis Pro Matched Springs set “, each spring’s stiffness rate has been individually measured and matched as a pair to provide the guaranty of a strictly identical stiffness rate value.
Atsushi Hara supervised the stiffness rate value.
