This E30 M3 style rear wing is designed to fit the rear trunk lid of all e30 models from 1984 to 1992 including convertibles. However it will not fit the M3 e30 model. The styling is very similar to the factory M3 rear wing. Since there is a considerable amount of down force at high speed attachment requires four 6mm bolts directly to the trunk. Construction is of a high quality hand laminated polyester fiberglass with a gray primer gel coat. Installation requires drilling, sanding priming, and paint.
