How about your opinion or past experiences. I have a '49 Chevy Pickup with a Mustang II front end. I need to add 1" to use the wheels I want to. A wheel change is not an option for several different reasons. Problem is I am torn between running 1" spacers with long studs added to my rotors or running the spacers/adapters with five drilled holes and 5 additonal studs. Some say that the long studs are subject to snap or break. Some say the spacer/adapter has twice the lugs twice the studs hence twice the chance of something coming loose.
