Selling my Krotov High Kick Duck-Tail Spoiler for Q50. It's poly, sticks on with double-sided 3M tape.
Painted Graphite Shadow. In fair condition - it got scuffed in the garage (see photo), could probably use a respray.
These are pretty rare - can only be ordered from Krotov in Russia (>30 days, not including any delays from current events)
