If you want crisper balance from your JJ ULTIMA, the Kyosho OTW150 PC Rear Wing helps reduce rear instability during fast sections. Made from resilient polycarbonate, it copes with frequent driving and club use.
Position the wing so all mounting holes line up and tighten screws progressively to avoid distortion. Check the mountings after a few runs and replace any worn hardware to keep the wing secure.
