Actually, I believe they're Turbo Twist II wheels. These start with #996 while the original Turbo Twists are 993 parts. I have the 18" Turbo Twists (993) on my car, but they're painted, not plated. Cheap plating is cheap and not usually long lasting. Good plating (triple plated - Cu, Ni, Cr) is pretty expensive but very durable and long-lasting, more upfront, but usually worth it in the long run.
