Front Spoilers

Hey guys, I would like to get some input. My intentions were to
reproduce the GM 3 piece front Vega spoiler after I did the front
valance. I have a NOS one but I am not that impressed with the fit.
I also have a new Dobi one but once again I am not that impressed
with the fit of that one either. I may just go ahead and design a
different one but I just wanted to get some feedback. If any of you
are interested in one, or if you have had one or the other and there
were things about it that you liked or disliked, please let me know.
My email is either <a href="/group/cosworthvegas/post?protectID=137107198191059178024218175024247208098145211">CSWRTH1@a...</a> or <a href="/group/cosworthvegas/post?protectID=251123221106207105075143203140176130071179066034209">VEGAMODS@a...</a> Thanks and
Happy Holidays, Chris

Can you clarify... Spoiler, Valance? Any photos that clearly show
these parts?

Chris,
For the 3 piece spoiler, would I need the vertical peice that always
brakes off? That part is missing on my car but I'm interested in
getting the three piece one. Does anyone know what the JC Whitney
front spoiler looks like?

Chris,

I am very interested in it, if it is the replacement for the 3pc as
my #2474 originally came with it. I believe it is like the one Jim
Reardin trashed in the autocross at 2002 roundup.

As others have posted, a pic would be nice. If you would like I can
put together a survey for our website www.cosworthvega.com

Regards,
Jerry

Chris W,
Is the chin spioler one part of the three piece spoiler? In other
words, are you making all three pieces, or just the third part as an
addition. Also, how much ground clearance will there be on a 75 CV?
Thanks for the clarifications.
~CHRIS L

Let me try to help. The valence is being reproduced by Chris. This is
the part that goes from fender to fender and is body color on color
cars. Attatched to this is a 2 foot wide black plastic piece that
deflects air upwards towards the radiator. This is the air deflector
(chin spoiler some call them), usually broken or missing from curbs
and such. These are reproduced by Dave Quarterman (604-469-9979,
$95). The 3 piece spoiler is a dealer installed accesory that bolts
to the valence and goes the full width slightly forward of the air
deflector. Spoilers like this are easily noticible on 79ish Trans Ams
and Monza Spyders. These are usually considered to be racing styled
pieces. However like most GM parts, fit is not very good on any of
these pieces. Chris spent a lot of extra time to ensure that the
valence was perfectly straight unlike the warped factory ones. His
version of the spoiler will likely be of considerable quality as
well. Ground clearance will likely be the same as the factory style
spoiler does not hang down any farther than the stock air deflector.
The DOBI style spoiler does hang down, reducing ground clearance by
two or three inches.

All Vegas had a molded plastic "spoiler" across the bottom of the
radiator that is known as a "deflector". The three-piece accessory
spoiler, or "air dam" (a line drawing is in the Chevrolet Power
Manuals) has one piece across the front and side pieces that wrap
around to the wheel wells. The center piece has recesses, the
backside of which can (and should) be cut out to form functional brake
cooling ducts. This three piece unit is attached OVER the OEM air
deflector.

It is very functional in the sense that it forces more air into the
radiator opening, reduces the amount of air that flows under the car,
and has the brake cooling ducts. It has performed very well for me
including race track hot lapping at speeds up to 120 MPH. My
perception from both the apparent pitch angle and handling
characteristics is that there is no signficant high speed lift with
the three piece front air dam. My on-track brake performance with
Monza brakes sans splash shields is also superb. It also makes the
car look better IMO.

As far as ground clearance is concerned, it's a bit higher than the
low point of the center cross member, and I've never damaged it, but I
am careful entering steeply inclined driveways and such. I can slide
my small floor jack under it. My car has stock '76 springs and
205/60R-13 tires.

I believe it would fit better if the center piece were slightly
shorter, side to side, as it is difficult to get the side pieces to
fit snugly against both fenders.

I think the piece that you are referring to is the air deflector or
chin spoiler as it is commonly called. It bolts to the car with the
valance but it is a separate piece that is often broken. The 3 piece
front airdam is the one that Jim Reardon hit a cone with during the
autocross at the NY roundup this year. I have one picture of Craig
Schmitz with one on his car and I will have to look and see if I have
any other shots of one installed like on Duke's car. From the emails
that I have got, I think that the consensus is that the 3 piece style
is preferred but it doesn't have to be exactly like the stock one
since it didn't fit all that well. I am also going to try and re-
design it so that it will use the same mounting locations as the
valance so that hopefully it can be installed without drilling holes
in the valance. I will keep you guys posted on the progress. Chris

Thanks Britt,

I was wondering when we would see a picture, they say a picture is
worth thousand words, I read more than a thousand words so far and
still wasn't sure of what it might look like, the picture from a
white car makes it easier to see the details.

I think my car might have had one at one point, I still have 3 holes
drilled on the bottom of the front fender.

To those of you that can't open the link, go to "Photos" and click
on the "76 Whi..."

Al

I had the GM three piece front spoiler on #2172 for several yeras. It
basically looks like a Vega version of the 1979 Trans AM style front
spoiler with the "splats" thaty kick air around the front tires. My
memory tells me that you had to "fit" the splats (the LH & RH outer
pieces to the front fender contours and bolt them to the inner fender
lip with sheet metal screws. The center portion mounted to each outer
piece with 2 bolts & nuts on each end and you had to drill two more
attachments to the lower valance thru a lip above the "brake ducts"
that was on the center section. It did need to have a fabricated
support at the center between the factory air deflector and center
section. There is a factory "tab" there to mount with the same screw
as the air deflector but it breaks easily. Ground clearance was never
a problem as long as you don't "feel" park against curbs.

According to the SCCA in thier official rulebook definitions --

SPOILER - A panel attatched to the body of a car at the front or
rear, intended to alter the airflow around or under that end of the
car when in motion.

AIR DAM - An air control device at the lower front of a car, intended
to divert some of the air which would normally pass under the car
when the car is in motion.

No definition for valence since it is a word traditionally used to
refer to cosmetic trim that have little or no function at speed.

Granted the SCCA is not the letter of the law, so that is why I used
physically descriptive terms and then applied labels to the to foster
ease of understanding. These terms are interchangable, however
spoiler can be used at both ends of the car. I remain confident of my
correct use of the terms valence, air dam and spoiler.

Chris is manufacturing the body color part that comes from the
factory spaning the distance from fender to fender below the bumper.
The 2 foot wide black plastic air deflector/dam/spoiler that is also
a factory part but broken on most Vegas is made by Dave Quarterman in
Canada. The new item in question is a three piece spoiler/dam/air
deflector that was offered through the parts department, and
advertised as a "spoiler" by GM.

Please review the previous posts as well as the picture link and it
will be quite evident what the new piece is that Chris is making.

We need to get our terminology straight:

A "spoiler" disturbs the air flow coming off the back of the car.
Spoilers go on the back of the car and create down force on the rear
suspension.

Air dams are installed on the front of the car and jam up the air in
the front to be used for air intake and down force on the front
suspension.

All Vegas came with a small plastic "air dam" or lip that hung down
in front of the radiator to help scoop or force air into the radiator.

So, whatcha' makin'?
