As stated, Zimmerman's are a great rotor. They're a popular application on Porsche.
Reviews of spare parts for Porsche
If you never get the brakes terribly hot (single high-energy braking events are fine, I'm talking extended periods of track or track-like driving here when I say "hot"), porsche OEM pads work great. If you do run the car under track or track-like conditions, the OEM pads never fade (in my experience), but they do wear out alarmingly fast.
I tried looking at different brands of pads for my 911. Just ended up going with OEM pads. Turns out most people think Porsche OEM is the best stuff and I've learned for many aspects of these cars that is true. This is very different from every other car I owned where you could either get better performance or reduced costs by going aftermarket. With my Porsche I couldn't find a pad that offered better daily driver + some hard driving performance... or was cheaper without sacrificing performance.
I have the Hawk Ceramic pads on one of my Porsche's and agree they are great pads, very good pedal feel, no squeal, and no dust.
For now sits on Bilstein PSS10's and gets driven on my days off.
I have Sumitoma HTR ZIII's on my car and they work great for a street tire. I am surprised how long the rear tires are lasting.
All I have to add is that I like Akebono Euro Pads.
Akebono's are expensive? News to me. I keep buying them because they offer no noticeable deficiency in braking compared to OEM in day to day driving, while making well less than half the amount of brake dust and come in substantially less expensive than OEM.
I ran a Porsche 993 as a daily driver and people would go wtf when I told them that Porsche wiper blades were $77 (worth it though as they worked well) etc
My dad put an Optima red top in his Porsche 930. He used the exact trickle charger you pictured for storage and because the car is driven only a couple of times per month in the summer. The battery was in there 2 years and I had to scramble late Friday night to install a replacement after it wouldn't start at the gas station (friendly attendant helped me bumpstart it). The battery stopped taking a charge.
