I know they claim to be safe even for performance applications,with the newer style offset wheels, but I would be very nervous the first time I dropped the hammer on my stroker from a dead stop.I have 17" x 9.5" C6 Z06 style wheels with 2.5" wheel adapters all around.
I looked through some old pics and this was the best shot of a wheel adapter that I could find. The hub is bolted to the wheel adapter with open ended wheel lugs and red locktite and the adapter has wheel studs which the wheel is bolted to. Made of 6061 T6 billet aluminum, CNC machined with pressed-in studs and open end lug nuts included.
I have been running them a couple years now with no issues.
Think I might try that style of rim on my 82.
