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?

It really won't make any difference in an autocross situation Jon. Only on the track do these ground effects really work wonders. On the track a splitter also needs to be balanced by a spoiler.

Giggle giggle snort.

Yes they do work at an Autocross if the event course layout is fast. anything over 45-50 MPH.

I have been to 4th gear before because I hit the 6250 RPM rev limiter in 3rd.

Anyway I lowered my air dam to the hieght if a 4x4 (3 3/4") when the car is at normal ride hieght (4 1/2")

It is even with the bumper pad when viewed from above the blade is 6" deep.
the under belly splitter board goes back to the line of the front axle and join nicely with the steering rack cover. made of 1/8" Luan laminated with layers of fiberglass. Strong enough for my 7yr old sone to stand on. and hit a cone without worry going over 60 MPH

I can feel the effects of heavier steering starting around 45-50 MPH.

My next one will be built to the limit of the rules and require struts to hold it up.
