BT Tech Rear Aero Spoiler!!

That air is coming from the side, not over the top where this would have any effect.

Unless you change the profile of the car significantly, you won't change that effect.

The maker stated that this would help reduce front end lift. Great, but that doesn't do anything for the side. If it does anything, it would improve overall handling.

If its cheap enough, go for it if you like. You won't lose much.

 

This is a quote from Brian's first post:

"A byproduct effect that this part has is that it greatly lessens the side wakes of larger vehicles that go by. "

I'll take my chances.

 

Can the pictures of the Spoiler be reposted?

Thanks

THANKS! Just installed the Spoiler - will test drive it later this week on the highway and I'm sure I notice the difference - thanks for a great product!

The anticipatory placebo effect in action.

 

OK, got my spoiler about a month ago but had to have it repainted becasue the color was way off. My car is Tidelands Pearl and the spoiler arrived looking like it was blue, but not the blue of the Prius. I had it repainted and it came out beautiful and just installed it this weekend, took about 4 minutes. Looks great now. Really looks sporty too.

 

Brian,

Have there been any reports/ research on how this would effect MPG?

 

All I can give you is my real world experiance. I have not noticed any difference in my MPG since I installed the Spoiler.

Here is my seat-of-the-pants reprt. I have driven the Prius several hundred miles now with the spoiler. It still looks cool AND I believe the car feels more stable driving down the road. It seems as though I am not being blown around as much as I used to be and when other traffic is passing me I really do not feel it now.

Brian- As for the paint, I used to be a painter and have a good eye for color. Both my brother and I looked at it and agreed the color was off, pretty far off actually. Not a big deal as my car had been hit on the rear bumper and the paint was scratched so I had it scheduled to go in for paint work anyway. I had the spoiler painted at the same time.

Now if someone could make sway bars for this car as well as some heavy-duty shocks.....

 

I've been looking thru the thread and forgive me if I missed this, but can someone post installation instructions? I'd like to see what's involved before ordering.

Thanks!

 

Hi Brian -

Trying to catch up on all the great gadgets available for the Prius since I just ordered my first one....

I'm a bit confused on the function of this part. I understand it is meant to reduce lift by breaking up some of the "wing shape" of the Prius profile. Of course the rear of the Prius does NOT come to a point link a wing does, and in fact, ends in a squared-of rear-end that begins with a sharp edge. That factory sharp edge would create some spoiled air at the back, which would tend to reduce the wing effect (On purpose, I'm willing to guess!). What is it that this part does differently than the sharp lip just beyond where this spoiler installs?

And regardless of all that, is there any empirical info that can be shared? Any measurements of decreased lift? Any evidence of functionality beyond "it seems to handle side gusts better"??

Thanks much!
