I would second that! On all counts!

..... now PJ has me "thinking"! ... and that usually gets expensive!
Especially if Matt's the lifeline!!

 

I just spent my weekend in Chicago supporting one of our dealers (Eurosport) while they hosted the local PCA for a day of tech sessions, food and friendship. One of the attendees was the regional aftersales manager from Porsche. I spoke with him about the LSDs and his position mirrors the position presented in the beginning of this thread. He's well aware of our rebuild program, as is Porsche, but told me that their internal experience, including the inspection of the vehicles and the feedback of the instructors at the Porsche Sport Driving Experience here in the states, is that there's nothing wrong or inadequate about the stock LSD.

He went on to say that if I can create a market and sell a product that makes the LSD perform better for the trackday guys, then more power to me. There was no animosity present and it was a very polite and genuine conversation, but the official position from Porsche seems to be that I am fixing a problem that doesn't exist.

 

well... then... I want my money back

 

Thanks for reporting Matt.

I can live with P being in denial re the LSD: We know the issue, it's not "dangerous" (it deteriorates gradually), and there is a solution (You).

Now, if we can just get them to own up to the coolant issue...

 

I am taking the coolant inssue into my own hands as we speak (type) -- I do not think Porsche will ever come around on that one in terms of a "recall"...

 

Nice report Matt... now it looks like I'll have to send you a 2011 GT3RS one as well:P

 

Then you have to return your hat at the same time....

 

Anyone that looks at a GT diff and compares it to stock...I did with my SC trans...holy moly night and day. What a unit, just fantastic on track with the 3.6.

 

What are you doing?

I just run water and Water Wetter. Would rather run over that than coolant but if there is a permanent fix I'm all ears.

 

Porsche, at least for my uses and with regards to this topic, is full of crap... braking the car in a straight line from 160 mph with the back end swaying all over the place... not confidence inspiring.

the stock diff is meant for leisurly street driving

In short... I am keeping the hat

Replacing the factory adhesive with welding -- check the feb(?) Excellence (has a blue speedster on the cover), there is an article dealing with this. I simply cannot stand the thought of puking coolant on the track and possibly cracking myself up, or even worse, one of my compadres...

some people remove stock fittings, clean them up, and weld them to the manifolds etc AND the other welding option is this kit on ebay (http://cgi.ebay.com/ebaymotors/Porsc...item3365199347)
I bought one of these kits as the seller is local and I provided it to my tech and told him that he could take whichever route he thought was better (stock fittings or the kit fittings) as he is a master welder and I trust his judgement.

The article explains some other "fix" options that are not as intensive as welding (pinning them in) and Sharwerks has posted a nice thread with pics of thier solution that has been working for years here (https://rennlist.com/forums/997-gt2-...ark-werks.html)

Yes it is a pain, yes it is engine out, yes it costs money, and no it has never happened to me... I hate doing it, but I have seen a massive coolant dump wreck resulting in 2 totaled cars (997-3 and Z06), and now that I am more in the know about the potential "porsche coolant issue", I simply cannot sit back in good conscience and not take action of any type.

With as much coverage as the problem is getting (SW thread, Excellence article, Savvyboy's mentioning of it to Porsche at the caviar launch of GT2RS, etc etc), I thought I would just suck it up and take preventive action.

of course I have no affiliation with the seller of the fitting kits other than I bought a set. It is also just my opinion that welding is the best option and my opinion is only that... my opinion.

EDIT: just to be clear, of the two cars that I saw totaled in the coolant incident, it was the vette that puked all the coolant that caused the problem

 

Welding or a tapped kit would be most permanent IMO. I've read the article in Excellence and any thread that pops up here.

Running over someone's coolant is something I greatly fear.

Someone is going to get killed over this issue and Porsche will be defending a lawsuit instead of doing what is right and figuring out a fix.

 

IMO since their parent is a listed company - VW, Porsche has to keep a profit margin that will keep their shareholders happy and at the same time maintain a level of quality that satisfies a majority of their client base. The last time I looked which was 4Q10 Porsche had an operating margin of 19% which 2X that of BMW, Merc...etc. So I'm not too surprised when they cut a few corners like the LSD. With regards to the coolant I just think that's unacceptable given the costs to rectify the problem. But heck 'there is still no substitute' despite all this.

 

agreed... you should be commended for using water wetter...


Agree -- there are very few cars that can take the beating of a GT3 and keep coming back for more... there is no substitute.

There is also right and wrong... and on the coolant fittings... Porsche is "wronger" than on the LSD imho

they read this board and they are aware of the issue... it is a business decision.

 

^^ Yes so time to revive the "Catastrophic..." thread.
