Carbon fiber defects
#16
I am lucky, did not realize there were so many problems. I had Esoteric inspect mine, they did the paint correction. I have been training to do this myself and have on other cars, but was afraid to on the 2RS. I am very happy with the cf. These are poor quality pics. Next time I am in the garage I will look again. So far, this appears to be the highest quality car I have owned. Esoteric said there were no paint defects that paint correction didn't take care of, and fewer on this car than most. Leather, stitching, other areas I have inspected look just right to me.

Where the parts is made makes no difference on the quality, it's the company that makes the difference. On my CGT and every other CGT on the marketplace, the rear diffuser is made in Italy and every single one of them has delaminated and needed a full respray of clearcoat. Of course, the Italian supplier went out of business many years later.
If China can make iPhones and MacBooks, they can make a simple product like a side air intake in carbon fiber. If you need to blame it on someone, you need to blame Porsche, who approved the spec of the product in the first place.

chinese probably have the best technology in CF manufacturing,
PAG prolly didnt pay them enough to do it
the piece shown was not well made, likely on $ constraint on the tech constraint.,
white CF is very light. it's really benefit if strength vs wt. if you simple want low wt like that intake side piece. just use plastic.
many ppl are fascinated with CF weave. you don't buy CF b/c of the weave. weave is the result of how you lay the fabric to get the strength you want. CF is not meant to look nice. in fact it should look if you designed it for layering of strength and min wt. some of the best CF bicycle frames are made of 100's of tiny little fabric. without paint it looks like POS, but that's not a concern if. yo want to use CF for the right purpose. just paint it after.
you know if like trying to use concrete in tensions. sure it could work, but conc is way higher in compressive strength. use the material right.
and if you WP has no effect now. it WILL. the clear coat and resin will turn yellow. it's only a matter to when not if.
it is the nature of the beast.
just like u will get wrinkled by the time you are 50yo, if not sooner.

^Pure words of wisdom. My father headed the composite materials division at an aerospace company making parts for satellites and rockets in 80s and 90s, he is baffled when he sees CF trim inside a car!

there is no VIN# on the part

And this is cold setup, no pressure CF fabrication. You do not get voids like that hood in a pressure/temp drawn autoclave.
What you do get from cold setup is low density yield resulting in CF that yellows soon in the future (Ferrari Scuderia intake/plenum recall).
I believe I saw Porsche were charging $18k for this Weissach option...Have profits become so important that it comes to this.... smh

It is not completely uncommon to see this but the QC department should have rejected this.

Going through something very similar to this on my RS currently. It is not a defect as far as separation of the clear and the carbon but sanding marks that can be seen once the hood is raised. This should have never left the factory. Now the problem here is the dealer is wanting to take a look at the defects with their own eyes (which I understand) but the car is currently at Detailed Designs Auto Spa getting the paint protection and Modesta coating on the car. The problem here is planning my schedule around their schedule of when they can look at the car just to tell me what they will do to clean up this mess. So far it is very frustrating because from the images you can see this is just on a part of the hood that cannot be seen until the hood is open. Add in the fact the area of the hood that is effected by this defect is also one of the parts of the hood with where the clear coat can be very thin. Beyond frustrating.

It doesn’t matter if the part was made in Germany, China or Zimbabwe. It is on Porsche to make sure things are right.

The rear quarter cf vents are very high quality regardless of them being made in China. I have handled a few sets and the tolerances are tight and real thought went into how the outward facing weave was laid.
The engine lid part is literally the nicest cf part I have ever held in my hands.
Front fender cf louvers are nice enough but not perfect. The not perfect part is an area no one will see unless they are removing them and it's reasonable to not expect otherwise unseen areas to be perfect.
The painted RS front fenders are well made but never have dialed in paint.
Rear bumpers are all plastered with superficial defects commensurate with the front bumper and front fenders.
CF mirrors are hazy/swirled up but otherwise *very well made*.
The hoods with exposed cf have room for improvement from what I have seen.
Overall, Porsche still makes the absolute best car at these pricepoints and even beyond. I imagine RS's must be produced using vendors which specialize in composite parts as it could not be a simple thing to produce such complex composite parts in-house for so many cars(and inventory). So, either Porsche locates someone who can produce enough good enough parts or they dumb down the car and make them with fewer composite parts.
The larger the composite part, the more likely that there will be unattractive aspects of them. And it is reasonable to not expect absolute perfection. But...and this is a big one, there can be defects that are deal breakers and they should be addressed by a dealer/Porsche.
There are bound to be challenges they face which it is easy to criticize from the outside but I stand by my statement that these are, baseline, the best performance cars for the money in terms of build quality/material make up.
Take all of this with a grain of salt as it's just my .02 and that isn't worth a whole bunch by itself. But I've been fortunate enough get up close and personal with a number of them.
