Wheel Spacers

When I was young & stupid I put a set of spacers through more hell than they deserved & never had a problem. Looking back on it I wonder why I wasn't killed. I launched the car for about 30 to 40 feet on a few occasions & I don't know why things never failed, but they didn't. As to whether they're a good idea or not, I'd say no, but my own experience says otherwise.
