you may need new axles(not for sure) but I know it shouldnt matter about the lugs, they are on the hubs, not the axles. As long as the axles are a correct fit into your hubs, you may only need axles. Call a part store and ask if they got axles for the current configuration, then ask if they got axles for the type R config. and see if the part # is different.once u have proper axles, see if the axle is a proper fit. hope that helped!
