| I mainly chose Z1 because they're very close to me so their shipping is very fast - standard ground arrives within 2 days. Huge advantage. Pros: big selection of parts, both OEM and aftermarket. Good prices. Always had prompt support when I called. Don't think they've ever messed up my order, and I have probably spent over $15K in various items. Cons: not as prompt email support, they really don't inform you about orders when there are delays (which really bothers me), and yes I have the oil cooler lines and turbo drain lines that are lined with the anti oil thing and they sweat like a fat man in a sprint marathon. I haven't bought many of their "house brand" items except recently bought the 675RS turbos, so I can't speak much about the quality until I test them out..but they're decent people from the encounters I've had with them. They may not be the best, but I definitely don't consider them "avoidable." But hey, maybe they just developed a strong undying love for me and give me special attention. May not be the same case to everyone.
