Yokomo D-178RAA Forward-Type Rear Drift Spring Set  [D-178RAA]

Rear forward-type drift spring for RWD

This spring set is designed for RWD drift setups where throttle response and launch acceleration are priorities. The springs are intentionally left uncoated to preserve the raw spring characteristics and deliver a direct mechanical response, helping the rear end react crisply to throttle inputs.

Use these forward-type rear springs when you want a propulsion-oriented feel that helps push the chassis out of a corner. They suit layouts and tuning approaches that favor quick initial acceleration from standstill or low-speed transitions, for example competition runs where start and exit traction are decisive.

Installation is straightforward: replace the stock rear springs with these, observe ride height and preload changes, and adjust shock damping and spring perch settings to balance the added forward bias. For tuning, pair with moderate rear damping and test incremental spring preload changes to find the desired slip and rotation characteristics on your track surface.
