XRAY Aluminum Upper Eccentric Clamp

Pros: You get a slight +1mm or a -1mm wheel base adjustment Lighter than stock 0mm part as you dont use composite bushing Cons: Less reliability due to not using composite bushing to protect bearings Use if you really want that tiny bit of more of stability for a longer wheel base on carpet or for more rotation on asphalt with a shorter wheel base. Would not recommend for rookies as this part tends to damage bearings easier if you crash with it. Definately a good option if your driving skills are advanced or if your track has few to no barriers you can hit hard
