You can feel the difference in turning performance when drifting. and you can definitely improve your time with grip.

A newly designed rotary retainer that does not restrict the movement of the spring in order to bring out 100% of the performance of the spring.
Since the performance of the spring that has not been used until now is released. you can feel further performance improvement by readjusting the spring rate and damping.

Can be used for all RC cars that can be installed regardless of category

*By using a 2mm down retainer. you can use a long spring such as a total length of 30mm.
*Many damper ends can be used.
