Yep the forged ones. I know someone with them on his 180SX - He says they weigh fark all, less than stockers. They also look damn hot. Theyre nice rims you really should consider them. If you dont know how to contact c-red see www.c-red.com.au
They won't cost you $4k though, less than that, i'm unsure of the price without tyres - his $4k included 17" 255 FM901s as well....
