Hi Alan:

Great Stuff... thanks for the contribution...

I'll put a draft up on the Z Car Home Page, send you the URL via e-mail (is it still the same as it was?). You can review the draft.... send corrections/edits as you see fit (copy/past plain text in e-mail will do, or if you can do the html coding that is fine also).. and once it meets your satisfaction... we'll link it to the main index.

If you have color images, or higher resolution images that you would like to use.. just e-mail them to me (I have no limit on size of files on my e-mail and high speed connections etc.).

kind regards,

Carl

Hello Carl,

How refreshing! Thanks for being so open to new information.

Fire away.

Cheers,

I have never thought of the factory decklid spoiler as a "BRE" spoiler. Ron, the one that is on your car has the two bumps on the inner side, correct? I was under the impression that this was the first model of the spoiler. Is this true? Also, the smoother one would be a latter design? What was the function of the two bumps? I think these are great looking spoilers. I would prefer one in glossy gunmetal of the latter version.

Alan, I have seen pictures of Fairlady Z's with ones that were painted body color and ones that were the color of the rear taillight panel (gunmetal). Was it a factory option to get them either way, a customer modification, or did it just happen by chance. I have seen early cars and late cars with the gunmetal or body color decklid spoiler so I am flabbergasted about their color's origin.

Zhead, If my car was as original as yours, I would put the decklid spoiler on, but not the BRE spook as the decklid spoiler could technically be a factory option on your 240z through looking at the sports catalog. However, if you were to get the front spook I would recommend the european spec spook airdam as it is more original to the car. It is your car and I know you will do what your gut tells you. Make it your own by doing small period modifications with high quality parts like Lachlan said. Modifications of this nature will not detract from the beauty or originality of your car. Good luck with the car.

p.s. Factory spoiler, NOT BRE spoiler. BRE made it popular here in the states, but it is still a Factory spoiler.

The Z 432 spoiler was sold by BRE then later Interpart in the United States, and to my knowledge was not sold through Nissan. Nissan sold a spoiler that was a smoothed out version of the 432 spoiler (without) the 2 bumps.

Pete Brock, a close friend of Mr. K probably got the rights to sell a part that was not offered in the united states in 1969 /70. The Spoiler on my car (which is a copy of the 432 spoiler) is the correct part for my replica, I have detailed photos from a Road and Track Magazine showing the two bumps.

Hi Chris (everyone)

In reference to Dr. Millspaugh's, (IZCC #11695), 1995/96 articles in Z Car Magazine, you will note, I hope, that at the end of the article he lists his sources of information:

"Sources: 1. CAR & DRIVER, May, 1974. The first generation Z-car tests referred to in "Aerodynamics, Part II" was the "Crisis Fighter Z Car", by Don Sherman. 2. For an in-depth technical coverage of automobile aerodynamics, the reader is urged to read "Aerodynamics of Road Vehicles" by Gino Sovran and Wolf-Heinrich Hucho in the Annual Revue of Fluid Mechanics, 1973."

Reference #1 is the same article I referenced, and Dr. Millspaugh reported most of the same information in his discussion. While he was still with us, I did have several conversations with Jim Cook related to the aerodynamic effectiveness of the various spoilers, aid dams and ground effects packages available for the 240-Z as well; another source mentioned by Dr. Millspaugh for his article.

I do agree that Dr. Millspaugh's articles would be good reading for anyone who is interested. Dr. Millspaugh has been kind enough to grant me permission, to put a copy of his articles on "the Z Car Home Page" for everyone to enjoy. (as the original Z Car Magazine is no longer in existence.. it isn't possible to get back issues from them, and there shouldn't be any copyright issues with them either.)

I'll post the URL here when I get the article scanned and on-line.

FWIW,

Carl

Hello Everyone:

For the people that are interested, the Article by Dr. Ben Millspaugh mentioned earlier can now be read on-line at: <a href=http://ZHome.com/ZAerodynamics/AeroMillspaughPart1.htm>http://ZHome.com/ZAerodynamics/AeroMillspaughPart1.htm</a>

The entire article is broken into three parts, and I've put hyper-links to connect them. It's about 12 pages in total length.

FWIW,

Carl

Hi Alan (everyone)

Per your offer to contribute the JDM Pace Car information and images to the Z Car Home Page; I've attempted to extract them from this thread, and created a first DRAFT of the article.

Now it's your turn... Review the "DRAFT" and send edits directly to me at my e-mail address: beck@becksystems.com (I'll cut/paste the plain text into the html).

The draft is not yet linked to the main index on "the Z Car Home" page... so the direct url is <a href=http://ZHome.com/Racing/JapanPace/FairladyZPace.htm>http://ZHome.com/Racing/JapanPace/FairladyZPace.htm</a>

thanks,

Carl

I'd consider the BRE spook, but I'd be more inclined to buy one from Classic Datsun rather than this one on eBay. I think you'd get a better quality part. It could always be removed later without much effort if you wished to do so. Good Luck

Hey, where is Bambikiller? I haven't seen him for ages. Something didn't happen to him did it?
