The 3Racing SAK-A538 Sakura M4 Pro spring set is specified for tuners who need repeatable, race-oriented suspension response. With measured dimensions M1.4 x 14 x 20.5, these springs allow targeted changes to roll stiffness and transient behaviour without compromising durability. Use them as part of a systematic setup workflow to refine balance and cornering characteristics.
Placed in the 3Racing Car Kit Parts category, this set is compatible with Sakura FGX configurations and supports precise component tuning. The springs are manufactured to deliver consistent free length and rate over repeated cycles, aiding setup validation and comparative testing. Their specification streamlines installation on standard shock bodies and helps maintain reproducible handling across practice runs.
