Rear Wing Position.....
Does moving the rear wing have much of an effect on rear end grip?
I know there is limited movement that can be achieved by the mounting position on the rear deck but there is also the position of the bodyshell. How much effect can the positions have or is the basic design of the bodyshell the main sticking point? Skiddins |
Moving the wing towards the front or rear of the car makes a noticable difference..... Easy to try if the wing is bolted on and the all the holes are already there.
Never tried moving the entire body. |

I realize this is a super super super old thread, but didn't want to start a new thread (since this one existed).
I recently purchased a Protoform Type-S body for my on-road 17.5 touring car. I notice that the rear wing has 3 positions to mount it. I know that each position will have a different effect on handling, can someone tell me ...what effect does moving the rear wing forward towards the front of the car vs back away from the car have? I can take a photo if it helps, ..but figure this should be an easy thing to answer. thanks, |

And vice versa, the further the forward the wing, the less rear stability you have, but you usually gain some steering as a consequence.
Don't ever remember starting this thread lol |

And still relevant :)
TT02 has the option to increase the rear wing angle. I am guessing the steeper the angle the higher the downforce. is that correct? |

Both the drag on the wing and the downforce of the wing acts on the perpendicular distance to the rear axle as a lever to remove the front downforce and put it on the rear. Moving the wing back increases the lever arm for the downforce proponent of the rear wing. Also, moving the wing up increases the lever arm for the drag proponent of the wing. So moving the wing back and/or up removes downforce on the front tires and puts it on the rear tires.

Unless you're seeing massive changes in ride height, you're not removing downforce.... But you are changing the center of pressure. |
The general trend is to mount the body farther forward on the chassis and then the wing as far back as possible. With the goal being to generate as much downforce as possible at BOTH ends of the car.

Trx1 Nailed it...Bam!:nod:

No, it acts on a virtual point defined more by the suspension geometry and spring rates. Not the rear axle.

The way I look at it, the downforce/drag on the rear wing reacts into the ground at the rear tire. And since it produces a moment at this point, it pushes down on the rear tire and pulls up on the front tire. The springs are just along for the ride. Increased load on the rear tire will compress the rear spring by Force/spring rate. The front spring will actually increase in length because of the moment removes some of the force on the front tire. Mind you, even though it removes some force on the front tires, it's not enough to remove all force down on the front tires. I'm open to anyone's interpretation of this, I'm always willing to learn as much as I can. EDIT: I think I could state this more clearly. When I say it removes front downforce, it doesn't really, there is the same amount of aero downforce on the front, it's just that some of that goes to the rear tires because of the lever moment of the rear wing. |
