This wouldn't work if I have an actual MR wing on my RA would it!?
Just thinking because the two side parts of the wing DO NOT come apart...

ok...do we not understand the concept tha we are FWD??? the last thing we need is downforce in the back. if anything get it in the front.

I couldn't agree more with Ralli04Art, we don't need anymore downforce in the rear, especially if you already have an aftermarket evo wing. We need a splitter of some sort.

Yes you are right on that one, but if you are on the track at higher speeds Ex: @165km/h,the back end of the car regardless if it is AWD or not will start to break away from you in the turns, i have experienced this first hand, so haveing a little more,but not tons of Down force on the rear would certanly help a little bit, so by doing this i will find out if it really does make a difference, and it will look cool at the same time.


Oh and by the way the motor i'm using is a Electric tilt steering that is used in a Bimmer, so this was a "Freebie" and it should work fairly well since it moves slow and doesent have a big turning radius, should be bang on for the amount of tilt that i want to achive. About 10 to 15deg should fine.

It seems that one person says something and the whole group are aerodynamics experts.... it's only making enough df to make a small difference... it's not causing any lift on the front it's only going to provide more stability in the rear... most people do not reach the speeds that it takes to make the wing effective anyways...

I did experience a similar situation over 160Km/h (around 100Mph). The back end of the car seems to get looser, like it's way too light compared to the front. It makes the back end wobble a bit and you feel like you would be ill advised to make any sudden steering input at that particular moment. I've been wondering how to correct this ever since... and once again, it's Kevin to the rescue!

^^ uh huh... no offense but that has nothing to do with a Lancer Ralliart... that's like saying "take the Enzo Ferrari for example"... I'm j/k... it just shows that the downforce lets you put more of a load on the tires... but for this application... the df will not even be noticable... maybe in your mind it will be but not when it is applied...

If you've ever put your hand out the window at 60Mph you know that even at that relatively low speed, the pressure that air can exert on a surface is quite formidable. So to say that no wing can exert downforce on a car traveling at 100Mph is like saying the Holocaust never took place... it's called denial.

Even a 1Mph wind will exert pressure on any given surface. It's not gonna be much though. If you can generate 100-150lbs more downforce on the back of the car at 100Mph, it surely is gonna be a good thing to have... and I'd be glad to have it.

I'll be sure to ask a friend of mine who's an engineer... I'll get back to you on the projected numbers.

BTW Kevin: 15 degrees would probably cause too much drag on the car... so you should probably aim for a more conservative 7 - 10 degrees. If it's gonna be a fixed ammount, it should be calculated first for optimal efficiency. But anyway, as I said I'll try and get Oli to make some calculations for us and I'll get back to you once I've heard from him.

^^Alright Ben Stein the Science Guy... my above post was direct towards the Bugatti post... we just posted at the same time... but what I'm saying is that it probably won't be noticed... I agree that it's there... that's why it's called a functional wing... but I just don't think that it will be noticeable... and I also agree that 15 degrees will more than likely cause some drag... but again it probably won't be noticed...

Speaking of FWD... look at our weight ratios. Extremely front-biased at 62% front : 38% rear. Ok so downforce in the rear won't help much with traction issues, but that's clearly not the point of this in FWD car. It's called stability.

Ok so everyone has they'er opinion on how things should work, and your entitled to it,but this is somthing i have though about doing for some time now, and if it works fine the car may be more stable in the rear, but if it doesn't work then it will be a cool novilty, but in anycase if you don't try something you'll never know if it works or not. And yes i will keep you all posted and post pictures when it's done, i am planning on starting this on the week-end hopfully it wont take too long


And by the way Workz, i was planning on a 10deg angle, this will be controlled by a 2 way toggle switch in the center console so at any given time i can control the angle up to a 10deg pitch, wich will be operated by a electric motor.
