the hubcentric rings aren't too important. you may need to get them if you get vibrations still after geting them balance. i did not get any for my wheels and have not had any problems. as far as the studs go, you can get them from WMW. http://www.waymotorworks.com/m14-to-...rsion-kit.htmlthe only thing is that the studs extend about 2in after the wheel is on so it might be hard to find long enough nuts, im not sure i never checked. i went with the open ended lug nuts because of that.
