Default body tuning tips

So ive been searching all over for some sort of information guide to tuning with the body. Specifically tc bodies. Mounting the body forward makes the car have more steering and back less steering, what about the wing? Some wings come with slots to be cut for what purpose, ive only found for an added wing affect, what does that even mean? Also cutting the rear portion after the rear wheel, i heard that it does something, but what, also mounting the wing higher/lower? More rake, on mount the body or less? Mounting the body higher or lower all together?, keeping which portions intact when cutting out the body to increase, or decrease what characteristics? Im sure there are other questions these are the ones i can think of off the top of my head. also i could be wrong on some of the things i said for what does what thats just what im told so far, im trying to figure out the facts

Is this what you read? http://racepf.com/how-to-tips-tcwing Aside from that and the body trim line in the other link I dont know that there is much discussion about aero tuning. I know that oval guys will sometimes intentionally mount it nose left. I think you may be in uncharted territory.

Ya I caught that on google a yesterday I guess ill have to go mess around with body/wings to see whats what I suppose ... should have a new body painted up tomorrow I butched my other one... the cars dialed so a bit of fine runing with the body/wing should be the little extra I need in the corners

Protoform sells a set of optional TC wings as well. One high downforce and one normal. Both are higher downforce than the stock wing IMO. They are thicker so they deflect less. They also stand up to abuse better. I thought it was a noticeable difference with no other changes.

You'd need a larger wing to get the same amount of downforce. Higher air speeds over the wing create more downforce. Going slower would produce less. So if you are going slower you would need more surface area on the wing to make up for the lack of downforce.

Alright so I did a little bit of testing, not as much as I wanted to, unfortunately the track changed too much from practice on race day to heat #1 and so on. So i was trying to tune on my car rather than work on my body tuning, as a fine tuning option. However I did a small amount of testing with the wings, and wings position. The mazdaspeed 6 body comes with a option cut out for the wing, after destroying my first one in an attempt, I did the 2nd one by hand, I liked how it felt, it was like more down force, and allowed it to rotate around the corners a bit better. I also tried moving the wing to the suggest first hole on the wing, and the suggested one on the body. IT WAS GARBAGE. The car was loose, and rotated WAY too much around every corner. I like the wing at least 10mm of the the end of the car, this also allows the are from the holes I cut into the wing to flow out "smoother" because its not hitting the body before it rolls off of it. Hopefully i can get some practice in on wednesday, and test a few more body tuning options. Oh i forgot i mount my bodies about 15mm past being flush with the front bumper, I have another one that I mounted closer about 10mm past the front bumper, I will probably switched to the one closer to the bumper, when i get my cars traction down a hair more, its skipping around the corner, because my track width is too far apart.

Have you tried moving the body more forward? Gives more turn in grip
