These are Works GP5 Mini Wheels Flairs/Arches kit available in Premium quality. This top quality arch kit sticks out 3.25", including lip, when bodylines (wheel arch and moulding lip) are kept original, allowing screws to remain visible and plastic wheel arch moulding to be retained. The rear arch stops precisely at the bumper seam line, staying true to the original ST works car design. These arches are faithful copies, with quality that truly reflects their price, making them a perfect upgrade for your classic Mini. Arch widths are measured off a new car and is the distance from the front wing (not the seam) to a point above the center of the front wheel, which is also the top center of the wheel and arch opening. Rear wheels usually appear to stick out further than the front owing to the general bodyshape, so allow an extra 1/4" with most arches. Widths when fitted are also dependent on the height arches are fitted and manufacturers trimmed sizes but should only vary 1/8-1/4" when fitted at the lowest position. Allow 1/8" for a rubber seal. **Never drill the bodywork until you are satisfied with the style, fittability, and trimming requirements for a good fit!  Finishing silver moulding strip is NOT included. Moulding sold separately. At Mini World Australia, we understand your passion for Classic Mini and Moke cars. Trust Mini World Australia for parts that honor the heritage and style of your beloved vehicle.
