Warning: long -- but that's because I'm passionate about modding cars, and if you're here, you should be, too. The short: TL;DR blah^3 ... Sean and his shop, Custom Functionz, rock and really know their stuff. I highly endorse them. The long: Custom Functionz. Wow, these guys are good. Great attitude, and know their stuff. You've probably seen their incredible talents on their hydrodipping and powdercoating, but they do more than that. Owned by Sean Pierce, his team really puts in the effort to make things right. I initially met Sean a car show (1st place Best KDM! :-) ). They had a display, and I was checking out their builds and really admiring them. Sean approached me, complimented my car, and saying he's seen it around. Even more surprising is he remembers my call from a year prior when I just asked questions. Wow! Anyway, I told him I think I have a leak in my air suspension setup, and that I have a few concerns, like some sounds coming from my coilovers. He invited me to his shop any time. Since I was out of the country, got quite busy when I returned, fast forward about 2 months later, and I finally stopped into his shop. (Had to tell the bossman I'm "working from home", and Sean let me use his wireless so I could connect to the office!) So call me queer, but I don't generally like going to shops, because a lot of them seem to think they're rappers, have their douchebag groupies hanging around, and I generally just don't feel comfortable. Not here; they were quite welcoming. My reason for going was for a leak. I can fix it, but I used that as an excuse to visit their shop to see if they could give me some ideas. As soon as I popped the trunk, Sean starts going on & on & on of what he can do to improve it, some ideas he can do, and more. ***THIS*** is what I wanted! I went there just for a quote, but hey, I'm connected to the office, and I'm all the way out there, so let's just do it. When my car is in the air, and he and his shop are inspecting my car, they find other things that could be polished up. They asked, and I concurred so they began working. Unfortunately, while they were working on my car, they found a couple more unexpected things so I agreed to fix those as well. Before I left, I heard the tiniest noise. I wasn't even going to mention it, but I know I would kick myself for not doing it later. Many shops would have been done, but no, he worked and worked and worked on it until that little sound was eliminated. He kept telling me how he won't let me leave until the job is 1.) safe and 2.) to 100% of my satisfaction. They went so far above and beyond my expectation. He knew I was coming, and he said he would squeeze me in. What we thought would be 1-2 hours turned into 7 (seven) hours. Their shop closes at 6:30, but my car wasn't finished until way past that. And he had to work on the other vehicles as well, so he left after 9PM. Unfortunately, part of the discovery they made is my bags were rubbing so I ordered some more they can replace them. The brackets that were holding them in place were rusted to something that you'd see on the sunken Titanic. When the parts came in, they sandblasted the brackets - and even the screws & other hardware (that attention to detail!!!) - and cerakoted everything to prevent rust. With tools, they milled down the part of the car where the bags were rubbing and then painted them so there's no exposed metal. Other things they did was redo my trunk setup like relocating the water trap to the specs that Air Lift recommend with their builds, redid the platform where everything sits by giving it a velvet "pillow" for everything to sit on, and then relocated cables while covering them in wire loom to give it a cleaner look. They did several more things to polish up the setup I had in there, so to me, I can see they genuinely know what they're doing. Custom Functionz. These guys rock. They're quite passionate about they do, friendly people, and professional. I just wish they were located a lot closer to me. Reading this, you're probably wondering why I did not let them to my initial install. Back then, there was no kit available for my car, and everything was 100% custom and made for my car, so I wanted someone with lots of experience. CF didn't have as much experience as much experience back then, but by now, I believe they have the most notches under their belt in the area, and what I really like about them is they don't just install cookie-cutter builds you normally see. Each & every build they do is 100% custom, and no 2 builds are alike. Because of this, companies like Air Lift Performance, what I have in my car, have now made them a licensed installer and distributor of their products. I wanted to be the "1st kid on the block" to have a bagged Optima. Now I wish I would have waited. read more
