custom adapters

yup

i know this is an old thread, but i have some adapter related questions...

all the adapters i see are hub-centric to the truck, and then clamped down to the truck with flat washer-styled lug nuts.....

what would be the pros and cons of adapters with a conical seat drilled into each hole of 8-lug holes, so both the lugnuts and hub center te adapter? much like any other aftermarket wheel?

or better yet, suppose i had some adapters that the hub-bore was larger than my truck... instead of milling out hub-centric rings, could i just machine the lug holes to take a standard 60 degree conical lug nut?

My adapters use conical lugnuts. There is a pic on the first page of my build thread.

Mine are also conical

genius! thanks guys!

All of our Chevy adapters use a conical seat and hub pilot for the 8 lug pattern.

lock, what would be the draw back of just one or the other? say... not hub centric, but conical seating of the adapters only?
