3.8 kgs to 4.0 kgs is the lowest weight u can get for 15 inch rims, its about the same weight as the desmond evo regamaster, only loses out to the CE28, about 2xx to 3xx gms lighter...
try weigh the ori rims, then u can tell the diff, my rough estimation is that is about almost half the weight as the cap ayam version...
Last time me also source for Regamaster but damn hard to find man!!! You are damn lucky if you manage to find!!! I saw one thread at Zth here (at selling stuff rim section) there is one seller looking for buyer price around RM3.8k this is worth buy~ :P
