For the Serpent Spyder RM and MM Serpent introduce these Ackerman steering arms in brass. The Spyder kits have 3 different nylon arms standard in the kti already to choose from.The brass version adds weights to the steeringblock assembly. This gives added stability to the front end.So, if you race on high bite dirt, or even astro/carpet, you can use them to reduce high speed steering / oversteer.
