Learn me some about rear spoilers
I'm now driving my 66 Chevelle eco project and am getting over 30 mpg.
Im working on a front air dam now and will probably add a small splitter to the bottom of it.
is there any kind or a rear spoiler I could add to the rear of the trunk lid to help airflow off the back?
Either a small wickerbill or a flat extension. Which would be better for economy? I don't need downforce.
And how do I calculate the overall height or length and the fore-aft placement along the trunk lid?
Thanks,
