We have a 1970 c-30 chevy drill team truck that has from the factory 18"wheels on split rims.I do not know what the [roblem with these rims are.We are pushing 789hp to the wheels and stop these trucks quicker and faster in 500 feet than a new z06.Go to youtube and look up piston knockers drill team and watch the vids with a 71'chevy c-30.tell me what you think of us new yorkers after that.
