This is my first ever photomatched model, so it could be slightly off. The Garage Fukui hood wing for the SW20 was built to keep the noses of MR-2s down. Formerly known as Phoenix Power, they were known for building very high power MR-2s and Skylines.
There are different versions of the wing which also have different mounting clamps, and some that have an adjustable blade. This one is not adjustable and would require to have holes in the endplates.
