Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi Guys, I'm really close to joining the club but still looking for the right car... I'm looking to purchase a MkI that's within flying distance. How can I tell if the kit is OEM or not? The taco wing is adjustable but the last MKI I saw had the rubber trim on the lip of the wing. I can't quite tell if this other car does or not. Also, for the front air dam, will there be areas for clipping on the OEM rubber/plastic mini splitter that always falls off? I'm just looking for signs of authenticity... Thanks so much!!

POST 2Original post

Look at the options sticker under the front hood. XAA is the option code for factory aerokit.

POST 3 / ORIGINAL POSTEROriginal post

From the photos it looks like the wing is missing the "Gurney flap" that I saw on the first car. I guess if it is glued on it is possible for it to fall off over time. Was the OEM wing fiberglass or ABS? Something else? Thanks! Grant

POST 4 / ORIGINAL POSTEROriginal post

The story is the kit was added at the dealer. XAA is definitely not on the sticker. Grant

POST 5Original post

My gurney flap was added by the dealer even though the car was born as an aero MK1 in 99. It is also a metal piece.

POST 6Original post

Compare it to mine. If it looks nothing like mine, yours is probably OEM. More seriously, check the underside for the correct Porsche decals. While you CAN buy decals aftermarket, few people bother. If you want to see "detail-oriented" jacked up to levels you never even wanted to imagine, go check out the 356 entries at a concours. Those dudes would import German air for inflating tires if it was available.

POST 7Original post

What is this "gurney flap"? The little flap on the top of the lower wing? As far as the front, there are holes for the front lip to mate up with. It either has the aero front it or it doesn't. The two look significantly different when you look at them side by side.

POST 8 / ORIGINAL POSTEROriginal post

Thanks guys. Yes this forum seems to refer to that piece on the lower lip as a "gourney flap". This car has an aero kit, I just wanted advice on how to determine if it is an OEM kit or a fiberglass reproduction. I hope that clears things up a bit.

POST 9 / ORIGINAL POSTEROriginal post

Gator, so it seems that the gourney flap may not have been installed on all OEM taco wings from the factory? Interesting if so.

POST 11Original post

All OEM should be polyurethane material(except rear spoiler) and have a "996.xxx.xx..." part number engraved/imprinted on it. Don't get too caught up on the Gurney flap. Not all came with it. It is held on by 3 holes so if it fell off, you would definitely notice the holes.

POST 12Original post

A factory Porsche taco tail will have "Made in France" stamped/engraved/imprinted on the inside.

POST 13 / ORIGINAL POSTEROriginal post

It has the "Turnwald" stamp on the underside with Porsche part number. I'm pretty sure this is OEM. In related news, I put a deposit on the car =) I'll be posting photos and an intro when I pick it up later this month. Thanks to the community's fast response in answer my questions so I could move forward with confidence! Grant

Turnwald is the company in France that manufactured the Taco wings for Porsche. I'm beginning to think either the very earliest or the very latest batch(es) from the company might've had slight variances than the majority. islaTurbine's wing might be in the same boat too.

If reference to alpine's comment, GrantH can you tell me what the build date is of your car? I've been on the hunt for clues concerning early aerokits.

POST 16 / ORIGINAL POSTEROriginal post

It's 02/00. I'm even more curious if this car has a dual-row IMS. What is your theory on the early aerokit cars? Grant

POST 17Original post

Not that it means much, but ours is an 04/00 C4 and it turned out to have a dual.

POST 18Original post

Gourney flap is small hospital type bed that is used to carry the ims bearing to morgue

POST 19Original post

Quotes source post: 12655475

I have a late '98 build 1999 model. It's a factory coded Aero car but the rear wing and front fascia don't have the "made in France" wording. They have everything from every other aspect that distinguishes factory kits from reproductions. It appears that possibly some of the early Aero cars didn't have all of the wording that the later ones did. It's just a theory and could be completely wrong. I was hoping yours could help corroborate it.

POST 20Original post

Quotes source posts: 12655545, 12646244

Your theory could still hold some water as Grant's car didnt' come with it from the factory but added on later by the dealer. Forgot if yours had any Turnwald markings on yours?

POST 21Original post

Quotes source post: 12655774

Yeah mine has the Turnwald and PD markings.

POST 22Original post

Well then nuff said. It's oem. Not from the factory but added later.

This is a source reference. Confirm exact model applicability in the original material.
