Square wire springs are a first-time development for RC drift use. These springs give you a wide range of rates with short travel.
The 4Edge series comes in 2 types. The first type is the 25mm free-length single type. The spring winding method adopts a semi-open shape on both ends.　
These springs are designed for easy handling on front use.
The other one is a twin-spring setup with a helper spring.　
The main spring has a free length of 20mm, and the helper spring uses a square wire shape.
Improved spring followability with lightweight spring seat. Improves traction performance when used on the rear.

See this hidden detail! The OD logo only pops up when the helper spring is totally squished. Single type comes in six different kinds: 8.5, 8.0, 7.5, 7.0, 6.5, and 6.0 turns. Twin type comes in six different kinds: 7.0, 6.5, 6.0, 5.5, 5.0, and 4.5 turns.
The spring seats are available in 3 colors: purple, red, and black.
