Mi3 Wishbones - Schumacher offer a range of flexible wishbones for the Mi3. The Graphite parts are the most rigid and will give most precise control of suspension geometry (U3127 and U3128). The Medium Flex wishbones offer a greater degree of flex which will give more traction and offers increased crash protection as it will flex during the impact (U3249 and U3250). The Extra Flex wishbones are very flexible indeed and offer great traction in very slippery conditions and will help to absorb impacts in crash situations (U3251 andU3252).
