■ YOKOMO has developed a new type of spring allowing for further fine tuning of your chassis to suit surface type and track layout!

■ The front springs are wound with a high pitch, the short high response spring is suitable for the high traction YD-2 series. Increasing the front tracking and feeling throughout cornering.

■ The rear springs come in 2 types, one tuned for more forward traction and one for more side grip. By using different materials and numbers of turns, these new additions to our spring range will allow you to tune to various types of circuits and road surfaces.

■ Due to the special characteristics of the material used to make them, the springs have not been coated or any treatment added to keep the springs at their original performance. Over time this may cause some discoloration on the spring edges and surface. To prevent this please lightly oil them with some bearing or machine oil.
