The Kyosho OTW124 Rear Shock Spring Set adds three spring rate options to help you tune rear behaviour on your OPTIMA. Whether tuning for tighter cornering or better stability down the straights, the S, M and H springs give useful setup choices.
Soft springs add compliance for broken or bumpy surfaces, medium is a go-to compromise for mixed tracks, and hard springs reduce body roll for higher speed sections. Swap quickly to evaluate changes to grip and balance.
Made for the Kyosho OPTIMA lineup, these springs fit directly on the rear shocks and do not require modification. They are a practical upgrade to dial in rear-end feel at the track.
