Is there a special Porsche tool to disconnect power steering lines? I've found the link, bought new hoses, but don't see how to disconnect the hose under the car (not the steering rack, and not at the reservoir and pump end) Thanks.

Recently purchased a 2011 997.2 Carrera S. Has 66,000 miles. Needs new rotors and pads. In looking at FCP euro and Pelican Parts, I, of course see Porsche OEM set, all four rotors, at about $1300. I also see Sebro cross drilled at about $614 a set, SHW at $576 per set, Simmermann at $703 per set, and slotted Sebro set at $737 per set. I prefer slotted, in general. Does anyone have experience in any of these other name brands.

Anyone have experience with using Sebro, SHW or Zimmerman brake rotors as replacement for original Porsche rotors. I understand that these name brands at some point supplied Porsche in the past. That doesn’t mean necessarily that these aftermarket rotors are still at those quality levels. Also. Anyone have experience with Brembro Ceramic brake pads? P65011N and P65014N ? $65 and $64 seems really cheap. Looking for good, maybe better than stock, ceramic pads. Like the lower a ...

Does anyone have a recommendation for matching door trim to carbon fiber from a brushed aluminum trim? Apparently the door trim is apart of the door panel and they are 3200 each.
