I'm looking at a 993 that has splitters installed (pic below). Is there an easy way to tell if they're OEM or not?

 

Yes, you can tell by looking at the air outlet grilles on the bottom:

GT3Tek Splitter:



OEM RS Splitter:

 

 

Now that that's solved, thanks ilko, I have a question on the retractable spoiler on the same car. It has what appears to be an exaggerated edge surrounding it. Is this OEM?

 

No.

 

That's what I thought. Any idea what companies make a part like this? Just curious to see if the same company makes the splitters. The owner has no clue about these parts. I'd probably need to locate a new OEM spoiler surround piece.

 

The aftermarket lip on the rear spoiler...worthless.

The fever I speak of, it's the old, "add front splitters" then mull over all the internet advice you'll get about the car being unbalanced. This is total BS, all the RS splitters do is reduce a little lift, they provide 0 downforce. According to the 993 RS/CS Porsche Factory Bulletin WKD 499 620, Section 5, page 2.....at 270 KPH, the "FA lift in Newtons" is 178. If the number is positive as is the 178, there is no downforce.

The next part of the syndrome, with front splitter, "I need to buy a 993 RS tail". The tail will produce down force at the 0, 3, 6 and 9 degrees of down angle, -119 (-25 Lbs), -297(-67 Lbs.), -535(-120 Lbs) -713(-161 Lbs) Keep in mind that these numbers are wind tunnel derived, at 270 KPH, or 162 MPH. Lots of luck getting to 162 MPH with a wing at 9 degrees of down angle and a stock 993 motor putting out 260 HP to the rear wheels on a good day.

I have been through Turn 2 at California Speedway with a stock tail 993 (scary), a 993 RS tail (marginal) and a 964 3.8RS tail with a 60" Crawford wing, with end caps and a Gurney lip (awesome). I also had 993 RS CS front splitters and 993 RS side skirts mounted up with the Crawford wing I got from Jae Lee at Mirage International in San Diego. Now here is where I eat some "Crow", I couldn't find, nor could I afford OEM 993 RS CS front splitters, or an OEM tail, pretty much NLA, so I went to Gert for a 993 RS CS knock off, Getty Design for the tail base.

When the car was in an earlier iteration as a 993 RS (clone) I used factory front splitter and side skirts with a Getty Design tail***. I was too cheap to spend the added bucks for the OEM tail. I wish I had...because when it was time to sell the after market tail I took a beating...which would NOT have been the case with a OEM tail. ***I also tried aftermarket (Not referring to Getty here) the fit and finish, and overall quality was poor to mediocre. My buddy bought one of these aftermarket tails, his painter spent 9 hours prepping it for paint.

But here is what I do know, and you can take this to the bank. Always buy OEM in contrast to aftermarket. It fits better, lasts longer and retains its value. The reciprocal is gospel truth with aftermarket. I have been down this road too many times, and its always the same scenario. Yes I saved money and sacrificed quality on the front end, but lost big bucks on the back end. Originality on parts is its own reward.

Yes, OEM will cost more, but it's worth more, it retains the panache of Porsche authenticity, and speaks volumes about your taste and values. And luckily, the original 993 RS OEM is available, for how much longer I don't know, from Gert at www.carnewal.com He operates out of Belgium and has an impeccable reputation, been selling to us Rennlisters for 20 years, more of less. I never hesitate to buy from Gert, nor should you.

 

Thanks for the detailed post, it gave me a laugh too! Yeah, I'm totally with you in regard to OEM retaining the "panache of Porsche authenticity". This is exactly why I was trying to ID these parts. I've never owned a 993 but I'm coming from a number of modified cars and I always use OEM parts for the exterior. The fit and finish of aftermarket parts never compares to OEM and I'd honestly rather pay more for OEM. I'm hoping that these are at least Porsche splitters but with the non-OEM spoiler trim, I have my doubts that the splitters are OEM. I'm going to have to get the seller to try to get a photo underneath them. I do like the look so I would most likely replace with OEM if they turn out to be aftermarket.

Also, thanks for the link! I might be ordering sooner than later.

 

The aftermarket spoiler lip is from GT3TEK as well and likely purchased at the same time as the front splitters in a package deal. Its held on with double sided tape.

I've had the RS splitters from GT3 on my 95 C2 for 4 years now. They fit perfectly (I installed them myself after getting them sprayed) and they have worn very well. When i get bored of the look I'll put the stock ones back on.

 

Downforce or not, I like that rear spoiler!

 

Thanks for helping to ID the spoiler lip. I was trying to find it on the GT3TEK but I couldn't. I was thinking the same in regard to the splitters and spolier lip being a package after learning this was an aftermarket spoiler lip. Do the splitters screw into the bumper anywhere? It looks like there were also screw holes on them based upon the pictures posted earlier in this tread?


Yeah, I actually don't mind the look either but I want to see this piece in person. I think it add's a little something to the back without taking away from the shape of the car too much.

 

"The aftermarket spoiler lip is from GT3TEK ..........It's held on with double sided tape." Do some research on GT3 TEK, I suspect that some will decide to go the double sided tape tape route and others will go for the OEM parts. Being that lots of us buy exterior parts, than later take them off, change to another "look", or see the car. Those of us that do this will have learned 1st hand that the "real cost" of an object is not just what you buy it for, it's what you can sell it for. 993 drivers are a living example...in my case, I bought my 993 (since sold) for about $63,000 in December of 1999. I sold it in November of 2017 for $53,000...probably could have sold it for a bit more, but had it's replacement in the garage, a 2004 GT3 with 11,000 miles. So discounting inflation, it cost me $10,000 over 17 years, 16% depreciation, about $50 a month. So we can say that the 993 held its value.

A somewhat analogous situation exists with OEM parts VS used parts, but on a much smaller scale. Example, I bought a set of 993 RS splitters...decided to go another direction later on, sold them fro nearly what I paid for them. I have sold aftermarket tails and take nearly a 60% hit....OEM for me.

 

Hey I am looking for this type of lips Does anyone know the part number?

I get it OEM is better ( I think they are $800 for the pair!!!!! ) but what the second best option? Cheers.

 

Order the splitters from Gert at Carnewal.com. If you must go the cheap route, check with Getty Design or MA Shaw. I have had experience with these 2 vendors over the years...recommend them. Re. Gert, he is the best of the best.

But here is what's going to happen when you buy the cheap ones...every time you look at the car, you'll know that for a few bucks more, you could have had the real deal. Sure the ones from XXXX in San Diego are cheap..but you get what you pay for. Save a few more pennies over the next few months...pass on Starbucks Veinte in the AM with a pastry. In a few short months, you'll have lost 5 + lbs and you'll have the money for a genuine OEM part.

 

im selling a pair of these oem--- used for $600 pm me if intrested
