Discussion and technical advice the SW20 MR2. 3S-GTE, 3S-GE, 3S-FE etc
Anything and everything to do with maintenance, modifications and electrical is in here for the Mk2.
was just browing through the net and stubled accross these
anybody got them fitted noticed a difference at high speeds?
1998+ Toyota MR2 Speed Flaps were introduced only to Japanese model MR2's in 1998 and 1999. When installed on your front bumper, right in front of your wheels, these deflect the wind at higher speeds around your wheels to help stabalize your MR2.
I bought some but I've not got round to fitting them yet. Damn, that's another job on the to-do list!
I have noticed a few VW and Audi ( I think it was) with these flaps fitted in front of the front wheels.
The idea is that they break up the flow of air under the tyre and reduce light front end feel at speed.
let me just state that i dont know much about aerodinamics ( if thats how you spell it ) but they dont look angled to flow the air anywhere. so the air flow is just hiting a wall of plastic.. how does this help?

Well assuming the aerodynamicists (and that *is* how you spell it) know their stuff they'll be designed to give a turbulent flow onto the front tyres. Rather than a smooth jet, intermittently.
You may know that smooth flow is good for lift on aircraft wings.
You don't want it turning on and off on the sides of your steered wheels, it'll "lift" them sideways.

Given that they are standard on a lot of modern cars they must do something

Right, Toyota wouldn't have wasted time putting them on the MR2 if they didn't do anything. At the last auto show just about every one of their non SUV/mini van models had these...they are even putting them in front of the rear wheels now too. You can see them in the front and rear of this new Camry: http://krang.motortrend.com/oftheyear/c ... n_view.jpg
Wow! Way to dig up an old post! Good use of the search engine!
And yes they do help reduce front end lightness!
I see you are in Chicago, my old man is fron there!

I'm not entirely convinced these work TBH - theyre actual proper name is a STONE deflector - not a WIND deflector. Be interested to know if anyone has experienced definitely noticeable improvement though...
That's strange that they would be listed under that name."Normal" stone deflectors are usually those strips of plastic that mount on the very front of the hood.
