Forward-bias rear springs for RWD drift setups

This spring set is intended for rear-wheel-drive drift rigs where a sharp throttle response and stronger launch acceleration are desired. The springs are left uncoated to keep their raw spring feel and deliver an immediate mechanical response, helping the rear end react cleanly to throttle inputs.

Fit these forward-type rear springs when you need a propulsion-oriented sensation that encourages the chassis to push out of corners. They fit tuning styles that prioritise quick initial acceleration from rest or low-speed transitions, suited to competitive runs where exit traction and response matter.

Installation is simple: swap the stock rear coils for these, check ride height and preload differences, and fine-tune shock damping and spring perch to balance the forward bias. For setup, start with moderate rear damping and alter spring preload incrementally while testing launch and rotation on your surface.

Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Which surfaces work best with these springs?

They are aimed primarily at carpet and asphalt, where the sharper throttle reaction and launching ability provide tangible benefits in corner exit and transitional acceleration.

Should I coat or paint these springs?

No. The surface is intentionally uncoated so the spring rate and feel remain true; coatings would alter the tactile response these springs were designed to give.

How to approach damping after fitment?

Begin with moderate rear damping and then tweak rebound and compression step by step while evaluating launches and mid-corner rotation to reach the balance you want.
