Well, If the hood scoop caused a ruckus, check out what the wing and spill plates will look like! :evil:

You must not be working on it. The floor is too clean.

Not a wing, spoiler by SCTA terminology. It looks OK to me, where is the precieved issue?

Wing has to stand off the body.

Looks like it does both? Woiler? Sping?

I'm glad you're happy with it -
I'm certain it will work well -
But gosh darn it, the lines on this car are just so sweet - especially the chop - I hate to see it have to go in this direction.

Dan, when I designed the spoiler, I studied the rules, and I think it is okay, but I have a question.  There is an open area at the front of the spoiler between the spoiler and the spill plate.  I can not find anything in the rule book that says this area has to be filled in.  Do you have any thoughts?  I am going to look more at other designs tonight.

John,

The area you describe must be filled in. In SCTA terminology a spoiler has one aero surface, wing has two or more. See page 47, the sentence just above fig. 9.

Because this is a Comp Coupe you are allowed a wing. The bottom of the wing must be a min. of 6" above the high point of the body. See page 66.

Dan, I just sent you an email on this. Maybe John and I are reading this incorrectly-surprise, huh?

John designed this to the Implementation Approach One, in 4.CC.8.

The sentence says "The design is allowed to fill in the horizontal gap between the leading edge of the spoiler and the body with a plate no farther forward than the centerline of the rear axle."

Are we to take it then, that we must fill in the horizontal gap?

Website Head Handlebar Holder's comment:

Remember that this is an unofficial forum.  Dan is welcome, of course, to offer his observations and help and such -- but a proper "ruling" must be sought and received through SCTA channels.  

We on the Forum are, of course, very interested in how this wing/spoiler situation plays out -- but don't take Dan's comments here as the final word.

Right, Dan?

Edit:  I forgot a letter.

SSS, I agree with you, and understand that.

My first sentence was "Dan, I just sent you an email on this." That email also was CC'd to the other gentlemen looking at the hood issue, and to John K.

Obviously, we are still learning the rules. I only ask these questions here,so that others that are building and learning can benefit from our misinterpretations and mistakes.

  What worries me about the design, is high pressure air from the end gaps getting under the spoiler and taking
away the low pressure and the resulting downforce, netting zero effect for your efforts.

 The 6'' above roofline rule for wings should be punted out with Superbowl effort and rewritten to say [ wings MAY be 6'' above roofline] so wings can be mounted in usual ways.

 Buddy...pita now, but if you moved the spoiler down and back you could fill in the spoiler to the fenders with more aero. This would also give more downforce leverage on rear tires. Hey, more traction and you might be able to take weight out :-D
