The Numbers:
My '90 5-spd came to me with a stock rear spoiler. Best Freeway mileage recently was 21.xx MPG.
Last month I removed my rear spoiler to see if it was creating more drag than downforce.
Now, I'm getting 23.4 MPG.
There's no doubt in my mind b/c i can easily see the increased mileage on my fuel gauge. It's that much better.
I've only had the car up to about 100 - 120 since the spoiler came off, but the car felt just as stable at that speed. (to me)
Because my car has it's own characteristics that could have an influence on my particular increase in mileage, I am asking anyone else to please also conduct this experiment and report back your findings.
I got the idea for this experiment from reading a few posts about spoilers and also looking at a previous month's cover picture here at sccoa.com. It was the salt flats car that went up to 190mph and had this piddly little nub of a spoiler on the back. So much for the needed downforce at higher speeds.
P.S. I also found some rust around the rear passenger side bolt hole where the spoiler attached to the trunk lid. So you might want to have some sand paper and touch-up paint with you if you attempt this.
Too bad the darn thing makes the car LOOK so much more sporty.
