Wing vs spoiler vs none on an X

[carl]

I think a big sprint car wing in place of the targa is the only way to go. For stock body, I greatly prefer the "ducktail", subtle but stylish and probably no function whatsoever.

Well , I can't really answer the original question (but I AM considering ditching the factory wing that someone put on my 85, maybe in favor of a duck tail spoiler). I can say that ever since getting serious about bicycle racing a a while ago I have re-thought those (ref the comments about autoX discounting aero) old preconceptions about the power of air flow. Yeah, makes a difference at pretty low speeds....where you feel that & where it makes a difference with our cars & their HP I don't know.

My feeling is that the factory Bertone wing is visually overwhelmed by the bulky, soft lines of the later engine cover.

I felt mine looked better with the early cover, when I had that setup.

I also used a Pontiac spoiler after I lost one end section, which didn't look that bad.

I prefer the ducktail I have now, it flows better with the softer lines of the late engine cover, and the wider, softer edged Dallara fenders.

I can't say I've felt any difference in handling with any of the variants.

GregS - I love the look of your engine cover here. Definitely not stock... looks like bare metal that was clear coated? Clearly a custom rear cover with the elongated vents. Quite nice.

Please do give details. Thanks.
