How do disc's add .25" to the width? They are the same thickness as stock aluminum brake drums that came on these cars. I can measure my factory OE aluminum drums from my car that I removed last year when I swapped to disc's when I get home tonight
How many cars came w/alum drums (not all G-bodys got alum drums)? How many still have those alum drums? I can tell you of the 5x 2-door Malibu's & 4x El Caminos that have been in my possession over the years, not one of them had alum drums. The steel drums are by far the more common option under a G-body. I have a pair of them though & could measure but .250" is prob accurate.
The point was/is...... Basing BS numbers off of what works on one car is not necessarily true on another similar car. Each cars overall combo can make a difference between working or not. You & I have covered this. Your wheel/tire combo works great for your Malibu. Pull them off your car & lets put them on my Malibu.... Without even trying, I can tell you they won't fit because my car is lower.
Since it's difficult to perceive tone, I'm not calling anyone/anything out, just trying to make sure EVERYONE understands this:

You can use posted numbers as a guide, but you still need to verify specifics on the exact vehicle.
