Has anyone put BONOSS wheel spacers on their wheels? I've never used spacers before and would appreciate some first hand accounts on the good and bad before I make a decision.

 

I have no experience with the BONOSS brand of wheel spacers, but I have tried other brands, with negative results.
NONE of the wheel spacers I tried would install correctly, fit properly, and function safely.
I came to the conclusion that Wheel Spacers on a Grand Marquis (Panther Chassis) are NOT a good idea.
If your aim was vehicle stability, you would be MUCH better off with Stabilizer Bar modifications.
