Reviews of OEM Porsche brake discs

My car was sold CPO with grooved rotors. The brakes sound like a 1990 caravan. 2x dealerships refused to replace them. I reported the issue almost immediately after taking ownership. Didn’t hear it in the test drive :/

The prices for parts (especially the brakes and oil and sparkplugs) and fluids are on the high side. Looks like they are only using Porsche parts while there are some excellent and much cheaper alternatives out there. Especially for brake rotors and pads.

Rotors will run you about $500 for a set. All OEM, same thing Porsche uses just without the Porsche sticker.

I've had them on my car a few months , I had to had a shim yo clear my rotors between caliper and bracket the rubbed his enough to annoy me and the peddle feels sponge but I also have stock brakes lines which expand and also haven't bleed my system completely plus i have a leaky master cylinder... So yes they work for me..

Maybe i'm pessimistic...I go by Steinberg's law: He beleived Murphy was an optimist......... When you sit in training with the Germans they obsess about every little tolerance, and potential problem and rotor wear & pad wear cause caliper pistons to come out further than they like and are a possible issue. (Piston gets cocked in its cylinder, seen it happen.) Eventually it rubs off........I raced 911s 's for 17 straight seasons, raced nascar Modifieds, and road raced Superbikes until recently.....I prefer to not have the possibility of some part not being as good as it ought to be when its my equipment...... Most people do not want to spend any $$ if they can avoid it, I get that too, been there before. Parts are cheap in the big picture, so I like all new and matching stuff so I can use it to the max without worrying until its time to do it again. I hear you about car knowledge, I don't profess to know everything, but when you do stuff 1000's of times on all types of vehicles, you do actually learn a little something... I will always replace my rotors, pads and lines if needed together, I respect your way for you. I think that the engineers may be overly cautious, but I'm going with them every time. By the way, i have burnt pads up and cracked rotors on the 911s as I am an extreme braker at the track, it was the only way to pass the faster cars, and you aren't out there to lose...(last 2 years -21 class wins, 18 2nds & 4 3rds) The 911 brakes in the 60s, 70, & 80s were not as good as they are now, they have evolved into stupendous brakes, but anything 1 man can build, another can break....... Our Roadrace motorcycles never got a patched tire for obvious reasons - 190+ on Daytona banks, but I'm good with a properly done inside tire repair patch on cars. lastly, the people on this board are driving a performance car and most drive them hard, so there would be no such thing as too much maintenance or overkill......I feel after all these years the German cars are the best engineered and with that there are tradeoffs, higher parts cost is a prominent one......I think VW is not too bad in that area compared to others...i'm good with $200 a set of rotors, some aren't..... I do not think the recommendation for matched set replacement is about selling more parts or the $$, they 100% believe that is the proper way to do the repair based on their design & knowledge of their product. I'm good with that. By the way measuring for enough thickness is fine, but as rotors should always be true & flat with new pads, that means turning and if they are close to undersize, now we are back to:::::::replacing them http://****************.com/smile/emthup.gif I'm to old, so i just freaking buy them put them on & I'm good for 30K + miles again..... Happy Wednesday!!!!!!

The porsche 911 GT3 comes with cross drilled vented rotors, and thats good enough for me. Its not that I think they're better than slotted, these are the first of either cross drilled or slotted rotors that I've used, and I think they work great, and I haven't experienced any problems with them, thats alllllll I'm saying.
