    Any one know if the aero rear spoiler makes the mirage better or no improvement over not having it at all?

    I'm very sure it does improve aerodynamics. How much? Probably not a ton, but I'm sure it does.

    Huge spoilers are always helpful ;-)

    Is there any difference with the curve spoiler with the other spoiler offered by mitsubishi (almost stright without brake light)? Is it really significant? Will i go for it or not?

    It's not going to be a huge difference. Realistically, the "aero" (curved down) spoiler probably improves highway speed fuel economy by a few percent, compared to no spoiler.

    The "sport" type spoiler probably hurts fuel economy by a few percent vs. no spoiler.



    Going from aero to sport would be the biggest change. Ballpark guess: 3-4% worse at highway speeds.

    I'm going to cover my entire lower grill in masking tape and see how it affects my MPG.

    I'm also going to keep an eye on the Scangauge, my water temp has difficulty staying above 175 in these frigid conditions.
