GROUP 2 FIBERGLASS white arch kit, sticks out 1.75" including lip, when bodylines (wheel arch and moulding lip) are kept original. Screws are visible and the chrome wheel arch moulding can be retained. These are copies of original ST Abingdon works arches. Rear arches stop at bumper seam line.

The quality of the arches is commensurate with the price. Most arches have minor flaws and may require trimming for a perfect fit but by fiiting one of the two types of sealing rubber available between the body and the arches, it makes fitment easier and a better finish quality is obtained, unless they are being moulded to the wing. 
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.** Arch's are supplied in White Gel coat finish.
