Ahead of next week’s 1/8th Onroad World Championship in the USA, Infinity has released a number of new parts for their IF18. A new hard front arm made from a harder material than the standard kit version offers sharp steering, a characteristic preferred by expert drivers. Another update on a standard kit part is the hard rear bushing set. Its use increases the rigidity of the suspension and improves corner speed. For down stop adjustment in the front and rear lower arms, new M4x8 round top set screws are available. The tip has a smooth round shape, making it difficult to damage the contact area with the main chassis.
