Today I have successfully mounted a 5-bolt Grant wheel onto my 2000 EK Civic. I post this because I was unable to find info on how to do it, so I went and discovered it myself. First, you need to purchase a 12-bolt hub adapter of decent quality off of Amazon or eBay for your EK. Afterwards, you can purchase a 5-bolt to 6-bolt Grant adapter to fit on said adapter hub. These can be found on eBay, Amazon, and even Summit racing. After you pull the wheel off and install your hub, position your Grant 5-6 to the most center position possible. After you tighten the adapter, intall the wheel itself, not using the 3-bolt extender found on most Grant wheels from O'rilleys. If the wheel is off center, do not stress. You can adjust the steering column under the dash, but I do recommend you have that portion of install done professionally. Good luck !!!🍀 🙂 If you have any questions, please feel free to reply and ask so, I'll be happy to help.
