Rear spoiler

[rdm1952]

I have decided to put a rear spoiler on my 71 Mach. Can I get some input as to who sells the best one out there? I have seen a couple at shows that are not worth the money or time to get and put on a car. Thanks in advance.

I wish mine didn't have one, even though it is a nice quality one. The grass is always greener I suppose . . .

I bought a fiberglass one from MU and happy with it.

Pricey but happy.

 

[jbojo]

I got mine from NPD, I am happy with it.

 

[mach71351c]

Got mine from NPD as well. Very satisfied with it.

I have an extra original if you are interested.

My car had one that was from NPD when I bought it. It is a good repo, has the correct shape, many don't. The only difference you can notice is the leading edge. It is flat whereas the original is rounded. Other than that, you'll be hard pressed to tell the difference.

The main problem I see around the shows is placement on the trunk and also many don't know which way around it goes. It's a 'wing' so the 'fat' edge goes forward, toward the window. The 429 Cougar and Mustang website has factory measurements for correct placement (Exterior). www.429mustangcougarinfo.50megs.com .

I can't be sure as my spoiler was already on my car, but I suspect that the one from NPD might show it to be 1/2" further back than factory on their instructions. Mine measures 1/2" different to factory, 10" not 9 1/2" to top bolt hole from the top edge of the trunk lid. I have to wonder if this is a way around licensing issues! I also checked this against a friend's car that has a factory installed spoiler.

If you CAN buy an original at a good price, that is the way to go. I paid only 90 bucks for mine at a flee market, but I've seen then for 400.

You mentioned a way around the license agreement. You do not have to have an agreement with Ford unless the item being reproduced has the Ford Logo or Mustang name or Logo.

Some say the spoiler has no affect on the car and does not work front or rear. I would disagree with them. If you drive a car without them at high speed and then put them on you can feel a big difference in how steady the car is. If you put your hand out the window at 130 mph and rotate you can feel huge pressure and also lift and down force depending on angle. Put the 5' rear spoiler on and it also breaks up the air coming across the top of the car and helps to fill the low pressure area at the rear of the car.

Well I love the look of it.. Both front and rear.. The front does help to get more air flow to the cooling system. I agree that the back one is best in high speed. But it does help in lower speed. Have tried min with an with out. There is a big difference. [sMILING FACE WITH SMILING EYES] [THUMBS UP SIGN] Regards Lars ??

David, We know that sometimes companies make similar products to replicate factory originals, but have to change them in certain ways so they can get around copyright issues. Case in point is the flat leading edge on the spoiler NPD sells. Other than it's lighter and different construction, the shape is otherwise the same, or very close to it. If I'm correct, the same spoiler was used on Mopar cars as well, so it might not have been totally a Ford product. Only the mounts have the Ford logo and number on, the spoiler does not ( that I could find anyway). The slightly different placement on the trunk lid, might also be a way around a Ford factory licensing. As I never had the template from the NPD spoiler, this is conjecture on my part. It could well have been miss-positioned by whom ever put it on, albeit exactly positioned, if that makes sense. I hope that explains my "theory".

As for downforce effect, absolutely it makes a difference as long as the angle of attack is correct to get the most out of it. That is a matter of playing with it. I remember talking to a guy who had his on backward. He said the car was awful at high speed, DUH! Next time I talked to him, he had changed it around and said he couldn't believe the difference.

I love the look of it too. All Mach 1's should have had them from the factory IMO.

 

[Jim and Jutta]

The original is really heavy, I also like the look of them.

I know I took the front and rear spoilers off and did flat out run and the car seemed to float around it was not solid in it's track. Put the spoilers back on and it was much more stable and tracked much better. There are no trademarks on the spoiler you can make it exactly the same and no issue from Ford just do not put their logo on it, lol.

No idea, but without mounting brackets...worthless IMO.

No trade marks on the spoiler.......... someone has copyright, may not be Ford, but the OEM supplier. If that's the case I do believe anyone making a replica would need to alter something to get around the copyright law. Just my humble opinion.

I have seen so-called replica spoilers that are way too thick, curved too much, wrong end shape and of course the flat leading edge.

Not even close!!

Here are a pair of originals

 

[mrmach1]

It's one of those thing you either love em or hate em. My car has the original Ford piece that came on the car and I wouldn't change a thing but if I had my druthers I'd rather not have it. Unless your driving at high speed (which I rarely if ever do) then it's all about semantics. Personally I like the lines of the car without that wing but being a purist I would never take it off my car. I wouldn't be able to sleep at night if I did and I need my rest. P.S you can't beat the original Ford pieces so if your serious then buy a used one and be happy.
