OEM/Original Porsche

Hello,

What is the difference between OEM and Original Porsche parts?

I'm going to buy some new brake discs, but i can choose between OEM and Original Porsche.

I thought that OEM parts was the original parts, but you learn as long as you live.

The price is ALOT higher with original porsche. 1 front discs OEM costs 35 where an Original Porsche costs 89

A big difference, I hope you guys can give me some advice as I normally only would go for Porsche parts.

Best regards
Kim

OEM = Original Equipment Manufaturer
Many times Porsche take a part, puts it in a Porsche box and add 50% to the price.
Hope this helps

Kim, you will also discover third parties selling OEM parts for our cars. Some of these OEM parts are indeed what Porsche puts in their boxes and sells for far more, such as Zimmerman brake discs.

However, I've purchased "OEM" parts from a company on eBay called Deutche Parts USA that claim they sell OEM parts... and they might be but they're not nearly as sturdy as the parts I could buy from Porsche so it's not worth the discount if you have to replace the part less than a year later.

In my opinion, there are some parts on our cars that should not be replaced with Porsche parts... the lower front control arms are one example. The bushings wear out prematurely. The remanufactured ones from Vertex last a lot longer because they are not rubber but made from a harder, more durable material.

Same thing goes with the oxygen sensors. www.oxygensensors.com sells Bosch versions with the correct connectors for 1/3 of the price at my Porsche parts counter.

Of course, anything anywhere is 1/3 the price of my local Porsche parts counter. They price gouge every chance they get!

Best thing to do is buy what others have bought and used for a long period of time and found to be worth the money paid, regardless of price.

Thanks for the replies

Can anyone give me some input wether I should go for OEM or Porsche parts when we are talking about brake pads and discs.

I can show you the total price difference here:

Porsche
4 pads 190,02
4 discs 361,14
Total 551,16

OEM
4 pads 99,9
4 discs 155
Total 254,9

A difference of 296,26 in dollars it is $473,31.

Thats alot of money, so I think I'm going to buy the OEM parts

Anyone knows about the brand of the OEM parts?

Best regards
Kim

You can make a much more informed purchase decision if you know the Brand or Manufacturer of the "OEM" parts. Sometimes they're truly the same, other times really not even close. There's defintely money to be saved if you do a little research.

I know you want to buy your parts closer to home, and you should, but it might be worth checking out pelicanparts.com for quality ratings on various manufacturers' parts. They sell many types of brake pads of varying levels of quality from a number of different manufacturers. If you liked your presumably original brake pads, you may want to go with Textar brand pads, which I believe are the same pads Porsche re-boxes and sells as its own for a lot more money. There are many comparable aftermarket pads that are just as good or better for the same or less money.

With the brake discs you need to make sure get ones that have the centers and disc edges zinc coated or they will rust. Porsche discs have been coated. Zimmermann sells ones that have been zinc coated and ones that have not. Most discs have not. You can paint them but they will eventually rust.

Thanks for the anwser. The reason why I'm not buying from pelican parts is because I live in Denmark. So the cheapest thing for me is to buy within Europe.
It's to expensive to buy it from US, because of shipping, taxes and so on.

The OEM parts from design911 is Textar.

So I believe it is them im going to buy

Thanks for the help

I cant see anywhere if the discs are zink coated.
If they're not, is it then just a matter of sending them to a specialist? I'm going to get my calipers painted red as well.

Or is that just plain stupid and expensive?

I've used Textar pads and they're good pads. You won't be disappointed in them for public road use, even hard driving. Now for track use, they may fade a bit.

The zinc coating is a nice thing to have to prevent hat rust on the discs, but not required by any means. Taking some high temp silver spray paint bought from the local auto parts shop and spraying the hats (tape off the rest of the disc) is a simple thing to do.

One more thing: be sure to buy some aftermarket stainless steel brake lines while you're doing all this brake work. They made my brake pedal far more responsive and stiff and it was very noticeable. It was the single best thing I have done to my braking system to upgrade it.

Oh yeah, I painted my rotors red and that's cool looking too!

Thanks RandallNeighbour

I'm going for the Teztar then. I'v been wondering about what the stainless steel brake lines does, I thought it was just for show. But thanks for sharing the info.
While I'm at it, I'm gonna buy those as well.

Didn't you mean you painted your calipers red?

I have everything for that, including the Porsche decals. So I'm ready to go

Yes, I meant calipers, not rotors!

And if you want to do it and have the time, buying high-temp clear coat to shoot on top of the finished caliper after the porsche stickers have been put on makes the whole package last a lot longer.

I didn't do this and mine have been just fine though... right up until I had to rebuild one of my calipers and the clamps I used to press in the cylinders tore up the lettering on one of the calipers

I have some clear coat also. But I'm thinking of sending them to a pro.
It's not before summertime, before I'm going to do it.
I'm in the danish navy, so currently I'm on Greenland

The stainless steel brake lines, is it 4 lines total for the whole car?

Yes, one brake line per wheel, unless you have the customized six wheel boxster and then you'll need two extra ones

One more question: I've read that when you change pads and discs you might come overcross some of the things on the caliper that is worn out. Is there any kit I can buy so I can change all that, while I'm down there?

You might need new brake pad wear sensors.

Ah yes, new caliper bolts. They must be replaced every time the caliper is removed from the hub. I hope your front ones back out easily. Mine did not and I moaned about that on a separate thread two years ago (search "caliper bolt" for it if you really want to read the whole sad story)

Kim, you could rebuild your calipers if you like, but the parts are not readily available and Porsche only sells the dust covers, not the piston gaskets. And if they're working now, I wouldn't open that can of worms if I were you.

From what I've read, you're doing just about all you should be doing at this point. You'll be very happy when you're all done, and your car will stop on a dime.

One last thought: Use the best brake fluid you can buy when you bleed the brake lines. I use this German stuff with a very high boiling point, even higher than the Porsche fluid. I can't recall the name right now, but I know other members will remember it and post it for you.

You should buy ATE Super Blue brake fluid instead of the generic dot 4 stuff listed above. It has a much higher boiling point and is well worth the extra money.

If you're not doing any track driving, you'll never need that higher boiling point. If you need it on the street, you deserve a trip straight to jail, do not pass go!
