I saw somewhere on here once a guy who used a router to turn down the inside of his zq8 rims to fit on a first gen. He gave the number of the router bit, think it was a porter cable bit. trying to doing a search but couldn't find it. he even had a video on youtube and I searched there but couldn't find it either. Anyone know anything about this? I wanted to turn mine down a bit to fit on my first gen for summer.
