Thread: Lets talk wings! Specifically C10 "Hakosuka" wings!

    Lets talk wings! Specifically C10 "Hakosuka" wings!

    Ok guys, been brainstorming trying to figure out some answers that just can't be answered alone. On the 1970-72 Skyline any trim, even GTR is there a factory equipped, Factory installed rear deck spoiler as in oem? I'm having the time of my life trying to track one down. I know it's 40+ old but still with it's popularity and extreme value a guy would think he would stumble across a oem spoiler in the auctions. Now I can find repro ones all day long, well cover that in a minute. But I'd prefer oem because I partially worried about fit of repos. Been talking with a couple of guys, the parts catalogs have been searched and it seems a oem rear spoiler doesn't exsist. One guy from Australia says that even on the GTR the rear deck spoiler and front lower chin spoiler was not oem but was a works race car addition to create downforce. Anyone know if this was true, or E is thinking that it's a Nissan sports option which makes sense to me. But as a Nissan sports option would there be any bowtie markings or indication to prove its authenticity?

    I have no problems with buying a reproduced copy as long as there's quality. There are some things I worry about when looking at what I think are repos though. I will included pictures. Hopefully no one minds me borrowing their pictures.

    If you look at some of the wings it slightly dips down in the middle towards the trunk like. Which is either a bad repo mold, or how it's mounted on the trunk.




    But if you look at these they are really nice and strait all the way across the deck lid.



    Any thoughts or opinions are greatly appreciated! If you don't like your pics up here just let me know and ill take them down. Thanks everyone!

    Weird... the pics aren't showing up for me...

    Probably my (slow) work connection, not JNC...



    For the record, I confirm I searched '71 and '72 parts catalogs and while there was a listed part number for the rear over-fenders of a KPGC10 coupe - there were no added body parts listed in either catalog. That means no chin spoiler, no trunk spoiler, no front over-fenders. Heck there were no over-fenders listed for 4 doors either.

    I've seen pictures of genuine rear over-fenders and they do have the Nissan part number labeled inside.

    Rubber Soul currently sells two spoilers, one with the "SKYLINE" all caps on the underside for 27000yen, and one without for 23000yen.
    Victory50 sells apparently exactly the same rear spoiler with "SKYLINE" all caps for 36000yen - no reason given why it's almost 10000yen more...

    Both of the ones WITH the all caps are described as being factory correct repros.

    For the cars whose spoilers look like they dip down in the middle - ie spoiler center section actually touches trunk lid - I believe that's a function of them having been mounted too far forward on the trunk lid. All the pics I've collected off the net over the years show a relatively set back spoiler with a clear gap between it and the trunk lid.



    As Jeff mentioned above, I believe that the rear spoiler was solely a Nissan Sports Option - which presumably could be optionally dealer installed for a street registered car if the owner chose to have that done. I've found dealer sales brochure pictures showing street GT-Rs WITH the rear wing - thus the opinion that it was dealer installed.

    It might be my posting them too, photobucket is terrible off the iPhone. I'm thinking ill more then likely just get the R+S replica with caps (SKYLINE) and hope for the best. Since I have your mounting template holes it should mount the same with the "gap."

    I can't remember where I read it but I think it someone's build thread they mounted there wing to where the top of the lift in the wing was parallel with the ending edge of the trunk. Maybe that makes the wing sit on the curve of the lid alittle making the wing dip back. As to when the wing is mounted maybe more forward when it doesn't dip back and it looks to dip down into the lid.

    Like I was telling Eric, maybe I'm just paranoid and there some goofy photo illusions playing tricks on my eyes. But I just want to be sure and get a good wing the first time since it is kind of spendy and timely to obtain the parts.

    In case Fatlace does not come to San Leandro vintageautosalon on Saturday, is someone on here intimately familiar with that car?
    In pics of that car it looks like the rear spoiler touches the trunk lid / dips down in the middle...

    Can someone say for sure if that's an optical illusion or not?

    Pretty interesting.

    Mine doesn't look like it dips down but it is definitely a low quality reproduction.
    There are cracks forming along the outside leading edges from the previous owner pulling/pushing on the wing to close the trunk.



    I'll probably go wingless and hang it on my wall eventually.

    Could you show pics of said cracks Princeton?

    So yours does not say SKYLINE in all caps on the downward facing surface?

    I have been looking at the two wings from the photos and the base where they mount is different. So in think one style sags and the other goes straight. Maybe some one else can look. The way the mounts blend into the wing also look different.

    OEM rear spoilers for the KPG deteriorate naturally over the years, first of all sagging and then cracking. There are plenty of copies, and copies of copies of copies out there, so unless you know exactly what you are looking at it's hard to come to a definitive conclusion. Much better to go back to the source:

    Correct part number for the OEM KPG rear spoiler was 99930-7102P, and it was supplied as a Nissan 'Sports Option' part to be fitted by dealers or private indivduals / companies. Nissan homologated it for use on their race cars by submitting an 'amendment' ( read: Evolution ) to the original T-161 JAF homologation. See scan below.

    Nissan also provided a 'Race & Rally' preparation manual for the KPG, and this shows details of the correct mounting positions for the rear spoiler. See scan below.

    That's a awesome piece of literature. The consensus is correct Eric was correct from the beginning! The KPG wing was a Nissan sports item, very cool in it's own right! That race/rally prep also shows that the wing is mounted with it sort of leaning back. So when it's mounted forward on the trunk, it might not lean back causing it to lean more forward closing the gap on the trunk kid itself!

    I'm gonna order the R+S version of the spoiler with engraved "SKYLINE" I will also use Eric's mounting template. I will report on wing quality!

    Thank you guys for all your help!
