I installed Rennline drilled aluminum pedals in my 2006 987 and 2009 987.2, and have been very happy with the look:
This time around I wanted something new so I ordered the Porsche OEM aluminum pedals from Suncoast ($445) and just installed them tonight in my 981CS with PDK:
My take on these pedals: well worth the expense. The aluminum plates are thick, solid, and have a very substantial feel. Part of the cost of these pedals is justified by the fact that the you get an entire replacement throttle assembly with this set, not just an aluminum plate (see installation notes below) Installation is more or less plug and play - no drilling required, but you should have a general idea of what you're doing or you will be frustrated. With that I've supplied some installation tips:
Brake pedal: the easiest of the three to install. Just pull the stock cover off and put the new one on over the steel brake pedal. Make sure the rubber sleeve is fully enveloped over the pedal or it may come off while driving.
Dead pedal: removal of the dead pedal in the 981 is different than how it comes off in the 987. There are 5-6 plastic studs behind the pedal that mount into the frame. I found the easiest way to remove it was to carefully slide a flat head screwdriver underneath the dead pedal from the right side at each attachment point and twist. The new pedal simply attaches by pressing in.
Gas pedal: this was the most challenging. First you need to use a T27 Torx screwdriver to unscrew the bolt at the upper left hand corner of the assembly. To remove the assembly, push upward and then pull toward you. There is a single electronic connection to the throttle assembly attached with a CPA lock:
The hardest part was figuring out how the CPA lock worked. What you need to do is push the gray tab downwards toward the end of the connector very firmly and the connector pops out. Attaching the connector to the new assembly requires the same action - align the connector with the socket and push downward on the gray tab until it clicks and pops up. Re-mount the assembly and screw down the T27 Torx bolt and you're done.
All in all the installation took about 30 minutes. It would have been quicker if I knew what to expect in removing the various stock components.
