wing comments, rear wing Options

[Glenn832]

This is just a fantastic forum! Being quite the newb, forgive me if I'm on the wrong thread. I need some advise and I know that it'll be freely if not copiously given. I like it already!

We've got a '74 that, at the moment, is in pieces. It's a street/track (little more focus on the track) baby that is getting some minor additions to help with high speed stability. One is the addition of a rear wing. There are two choices. As you can see from the pics, it's not pretty but at this point that's not the point.

What do you think about aerodynamics/functionality and also aesthetics?

I have a wing it is functional and it doesn't bend the deck lid.

Niether of the ones posted in the pictures will have any effect on downforce or stability at speed.

Because if the vertical rear window the air is insanely dirty and scrambled. Only way to get air to a wing is put it up high or use vortex generators on the roof and the wing only needs to be half as high.

and a splitter is absolutely required with the use of a wing. I have tried the wing with no splitter DON'T DO IT !!!!!!!

Thanks all for your input. I should have mentioned that we're building a dam with splitter as well. I'll post some pics of that when available. I really had no idea that the vertical rear window would mess things up that bad. Yet on the other hand, it precludes the use of an effective wing! Less messing around before you can get out on the track.

Another responder said that horsepower should be a prerequisite for using a wing. Well, we've got a little LT1 that does the trick. This past season's track sessions proved the necessity of a dam with splitter to keep the front end from "sight-seeing" at over 120mph.

Thanks guys, again. Your input is greatly appreciated.
