I figured it was time to update this thread. Here's the plan as it stands today. Forgive the cheesy "stage" monikers. They just help me organize my thoughts.

Why did I pick these parts and vendors? All of this is subject to change, so feel free to give me feedback on your experiences. More information from Camaro5 means a better build.
- Gen5DIY is an awesome vendor who answered all my questions. Ofer is a huge help, and I would recommend anyone considering one of their custom projects call him.
- ******** took great care of me and is known to produce high-quality subwoofer enclosures for the Camaro. They make an exclusive RCA harness for the Camaro, ensuring that I didn't have to tap any wires. As a complete novice, this made my install easy without paying a professional.
- Jannetty Racing has an excellent owner. Ted has taken some time to talk to me about my build. Whether or not anything on this thread comes from him is no indication of the quality of tuner that he is. If you aren't at least considering Jannetty for your build, you need to consider it. He also has a unique program that offers custom dyno tuning with parts that you order from him. This is a great deal not offered by any other vendor to my knowledge.
- RDP Motorsports also has a great owner. Steve also took some time to talk to me and offered me solid input on my build. Most of my parts are coming from RDP for good reason.
- Cold Air Inductions has the best results, according to Steve at RDP. I originally considered Roto-Fab due to the OEM-like flexible joints, but I've searched for justification of my concerns and found them unsubstantiated. While I'm still confident that Roto-Fab is the more OEM-styled and probably safer intake, CAI brand has been recommended so many times on Camaro5 that I can't ignore it.
- BBK is the recommended throttle body due to the 102mm size getting the best results on RDP's dyno. This is best installed with forced induction.
- ACS Composite is the only brand making the mail slot functional to my knowledge. While I had no choice, I will point out that the item I received is of OEM quality, and I look forward to having it installed.
- AEM was the recommended company by Jannetty for my data-logging gauge. I will probably buy on eBay due to the ridiculously low price there. My last experience with AEM was on a 2005 Cobalt for an intake.
- SCT is one of several tuning options available for Jannetty and RDP. The X4 is a great diagnostic device, capable of identifying codes and communicating with a tuner via PC. While I find the PC requirement aggravating as a Mac user, it is a nice piece of equipment.
- Chevrolet Performance offers some of the OEM items I want for my build. As much respect and enthusiasm as I have for aftermarket options, I'm convinced that GM builds the better sways bars, strut brace, and some other goodies that I'll be using. If anyone wants to try to prove me wrong, please proceed.
