Ok Ok sorry I tought you were saying that there were some actual carbon sway bar that broke as I broke the drop link but was wondering if the actual sway bar was also weak

Looking at the pictures the sway bar end is different compared to a non carbon one

Does anyone know if the adjustable drop links made for the normal gt3 would fit?

If you want to replace, I recommend you buy the non-WP 3RS ones instead.

Was the car corner balanced? Corner balancing without drop links can increase the pre-load on the sway bar and coupled with the car being lowered and higher g-loads, might have resulted in a failure. Admittedly, I think carbon sway bars are pretty cool, so personally I would just get 'em covered until warranty expires then can switch out for drop links/std metal sway if keeps cropping up as an issue.

The car was not corner balanced but was lowered and geometry adjusted for track but after that only used a few hundred miles on street.

What you say makes sense but still Manthey and others lower the cars with oem drop links and you should expect the carbon ones to be as resistant as the metal ones.... if they are not then it s not a real upgrade but another thing that limits how you can use and adjust the car...

The metal ones break too. I had a set break on a 996 GT3 I had while on track before. Car was lowered and aligned for the track before going out to Road Atlanta. That was years ago so I don't remember where it broke on track but I do remember the handling got funky while on track. The solution that never broke again was to add adjustable endlinks to the suspension. This allowed them to be the proper length without putting preload on the bars with the lowered setup.

Another data point is to read through this 997 thread. The car in question hasn't been on track but the suspension started acting funny. Turns out one of the sway bar end links was bent and best guess is where he was driving it on the street caused too much stress on the endlink while going over a curb, out a steep driveway, etc. https://rennlist.com/forums/997-gt2-...-collapse.html

So I have a 991.2 WP GT3RS and I do feel that overtime it will be interesting to see how the carbon bars do hold up. I do know that if I lower my RS any I will probably add adjustable endlinks on the car to make sure it is setup properly.

Do you think that the adjustable links could fit with the weissach carbon sway bars that are different at their end?

I have adjusted these CF drop links a lot of times already.

My car rides higher than stock at the back, and there is a tad of preload back there. I'm dropping rear ride to stock, so preload should not be a problem.

My front is lowered 8mm and there is just a little of preload, nothing critical. But as cars lean hard and go over bumps, these drop links take a beating. I would not be surprised if I break a CF link, because I have bended or broken drop links before (the steel ones), except the sturdy and adjustable ones (Tarett).

However, adding a steel drop link could make the anti-sway CF bar the weak link, and I doubt warranty will cover a new anti-sway $$$ carbon sway bar if aftermarket drop links are being used.

A few experienced track guys advised on this possibly happening, and it is happening. Porsche doesn't seem to test their stuff that much, or they are relying too much on Chinese manufacturing.

I have a pair of stock steel links sitting around, I will measure and compare them to the stock CF WP links on the front axle at some point next week, as I would like to have a spare handy in case of breakage.

I was worried about that with WP, Besides I don’t love the look and price.

What is the list price of the carbon drop links?

Maxi_z

They cost about 900 euros without tax in europe

Maxi_z

Yes I also tought about that as we don t know how strong are the sway bars but I would say that they are still a stronger part and if they work as intended they should not brake

I asked Manthey and they say they did not had any failures with the weissach links but they also say that with the standard suspension they don t lower the cars weissach or not

I was surprised as if you see on youtube and pictures there are some 991.2 gt3 rs that look to be lower than standard and they lowered my 991.1 gt3

BTW I will probably put the car back to standard ride or close to it

I spoke with Tarett and they can probably do some link that would work with the carbon weissach pack

Nizer

No way that's true.

Maxi_z

BTW they say they don t lower cars with standard suspension but they lower them if fitted with Manthey KW coilovers and other parts

But I don t know if that s true or if they only do not lower Weissach pack cars

Good point! Hopefully this is just a bad part from the parts bin and not too serious.
