I just ordered some BFG 315/30/18 drag radials which will go on my 10.5 wheels. I want to move the wheels out and was looking at getting the Maximum Motorsports 25mm wheel spacers with built in studs. My concern is if they will come in contact with the fender lip if they bottom out. Any thoughts? The rear wheels are AFS and I believe they have +27mm offset with 6.9 backspacing. Thanks in advance.
