Well i told them that i check out those other sites. Here is what they said.

"for total conversion kits more than 28 items with air freight direct deliver to your door step cost only about S$4,800 with painted color indeed is very good deal, because the full package include every things you need for the conversion, moreover it is make of Grade A PFRP.and direct mould from actual Mugen RR ( able to provide evidence to proof that it is direct fabricate from actual car)

Hope you can consider our offer, understand you have checked Aeimpex and 12 hrs, both kits from Malaysia and they fabricate from sketch , because there is not RR in Malaysia, I know how much they offer, I don't think that they able to provide courier service to your doorstep. ( quality wise and workmanship can see from their photo they provided)."
