Team Bomber lightweight 2mm offset spring retainer
From Team Bomber for the TB-AK12 series is this lightweight spring retainer with 2mm offset. With a standard spring retainer, if you extend the length of the pitching damper and increase the rebound stroke, the spring tension is stronger and it is impossible to reduce the height of the chassis centre part. However, installing this lightweight spring retainer with the 2mm offset increases the range of the spring tension adjustment, so it is possible to achieve the ideal height of the car without changing the type of spring.
