View Full Version : Wings and things

:confused: At our track every one runs a wing off the body or spoiler.
Every kit has wing mounts for the pod. AKA slippery conditions out doors . Is the idea to reduce rolling resistance in the corners and free up the car. Can you use a harder tire with the pod wing to achieve the same thing. Thus reduce rolling resistance. Please when replying give some principles so I can know why things work . It is really fun to try new things and figure out how it works.
Thanks Dan

3 pinks and a purple with a medium wing on a THD body for me in single cell at E. Ridge for me, Dan

what I always looked at (between POD mount and BODY mount) is this...

LOOK what gets pressure when you press in the back of a BODY mounted wing.

It applies the drag or downforce (which ever you want to call it) on the rear body mounts...which are attached at the back of the chassis.

Then look where a POD mounted wing mounts, and mount one up and press on the back of the wing...and see what and where, and how it applies the pressure.

It mounts to the rear of the POD, usually with leverage but directly to the rear tires.

IMHO the 'drag' is the same, but the downforce to the rear tires is decreased on the body, but provides enough for most cars on a track with a decent amount of traction.

On slippery tracks we use to mount them on the POD... (It's been a long time since I ran a POD mount)

(I always ran extra heavy wing wire on pod mounted wings too, large enough you had to redrill the holes in the mounts..cause I didn't like a bouncy or floppy wing)

Good points.
So the body wing distibutes the pressure more on whole the chassis thru the body. The wing pod applies pressure more directly to the rear axle. So during acceleration it pulls the pod up generating force to the rear tires. Pulling back on the center shock. Which takes wiegth of the front end.
So for carpet racing the body wing creates a less drastic movement of the pod.
Been reading your posts about the Hobby. Been doing this for 20 plus years. set up all kinds of tracks and lots of different clubs.
Went to Watkin's Glen after HS graduation and watched the trans Am series with the big guns Donahue, Savage, ETC. really fun. The weekend was great my point is they had the formula V's there and they were slow close the racing was unreal.
It is great to go faaaaast but having a tactical duel when you wheel to wheel next to a guy looking for that move or fake to pass him is what racing is all about. I do not want to out motor or battery the guy but fake his socks off and pass or he holds me off great stuff. Love the brushless stuff and hope the single sell lipo works well. keep posting you ideas. S:thumbsup:ome of us do really read and under stand it.
Cheers Dan

does any one realy like a floppy wing???

Body mount (wing or spoiler) pushes down in the chassis and the pressure goes through the center shock and spring. Relative to a pod mount setup your center spring will be heavier with a little more preload

Pod mount pushes down directly on the rear axle but changes angle wildly as the suspension moves. Plus, pod mount is attached via a long thin wire whitch acts like a spring. This adds a lot of vibrations directly to the rear pod: bad idea.

It is a popular myth that pod mount does not lift the nose of the car while body mount does. You cannot push down *behind* the rear tires without creating a lifting moment at the front. In the case of the pod mount the nose-lifting forces simply act through the T-Plate.

In short: Oval is about precision. Body mounted is very controllable and precise while pod mounted is not. It's one of those evolutionary equipment changes that we've seen in the hobby. There are still fast guys out there with pod mounted wings, but I think they'd be faster still with a body mounted setup.

around here some people have there wing one the back window some have it mounted on the rear deck lid other than it being moved back how does this change the car. most on the rear are solid and cant slide the back window can slide forward and back ( not with out losing a screw or two)

I use the darkside mount and a lexan brace between the bottom of the wing and rear deck. The lexan brace is two pieces of scrap lexan that I bent, slotted, and screwed together. The slots are in different axises so I can adjust the wing and sinch the brace down. For my setup (outdoor SS) the wing is below the roofline over the deck. I run it parallel to the ground and mostly just bend more or less angle into the lip as needed.
