These huge majongas measure 10.5x17 inches and wear Nitto 315/35R17 Drag Radials. Topline Products told us this one-piece cast wheel would fit under there without rubbing. We didn't believe them, until we tried it. We had the baseball bat ready to roll the fender lip, but there was no contact--even with a 1.5-inch lowering spring out back. Hint: Be prepared to bevel the hub openings with a rasp if these go on the rear of a Camaro or Firebird.
