For sale here is a Genuine BMW Class II Wing for BMW E36 Sedan. This is the 318is/4 Class 2 wing specific to sedans but it also (incorrectly) known as LTW , Lightweight or M3 GT.

This wing is a mix of parts as follows:The base of this wing is a brand new, never used, Genuine BMW part.

The top of this wing was purchased new in ~2015 at a US dealer before they went NLA. It has a single paint job on it (Daytona Violet) and is highlighted by having immaculate mounting studs with zero corrosion, or repairs. Most used tops, especially given most come from Europe, have rotted or repaired mounting studs. There are some scratches in the Daytona Violet paint work. This all needs to be stripped down and repainted to match your car.

The risers are replicas. They fit and look ok, but they are nothing like the Original BMW version... but originals sell for $3k minimum by themselves. There are some scratches and touchup in the Daytona Violet paint work. These need to be stripped down and repainted to match your car.

The sedan Class 2 is one of four variants of OEM wings offered on the E36. Indepth details can be found here:
