Sid Watson is the guy who makes these now. the wings are great quality, Sid makes Fibreglass pannels for lots of different cars so has a wealth of experience. He can make them lightweight for competition using matting techniques, regular style (bathtub style) lightweight, regular or strong. All have re-enforced mounting/stress points.

The finish can be in a selection of colors which is handy expecially if you are looking to use low opacity paints or to help hide chips.

Generally you can't tell the difference without feeling under the arches for the tell tail glass stream texture on the inside.

In terms of fitting, best to make paper templates using your existing wings inner edge (assuming they are not bent). A diamond 2-3 inch rotary cutter provides a great finish and is easy to use. If you are sorting out all the wings, they comes as blanks so if you want a low-line look you can easily trim less off the blanks for a "wide arch" look.

Nothing to do with Sid, only a happy and re-occuring customer.
