Ducktail spoiler

Part of the idea might have been to not need any changes to the trunk lid lift springs. The ABS spoiler is quite a bit lighter than even the MAS fiberglass version, which has fairly thin fiberglass. Or maybe DC was just cheap and the ABS was the best way to mass produce, hard to say.

I read somewhere that they did actually test the ducktail spoiler on a road course, and that the use of the spoiler resulted in a 10mph increase in the straight away top speed. I’ve never seen any data for that though, so who knows. I don’t remember where I read it at this point either, and honestly a 10mph increase in a straight away seems pretty optimistic. Probably just magazine bench racing.
