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 & 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 & 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 &U3252).
