As said on the phone dude don't think DMAX are copies of anything... they make their own stuff and if it looks similar to URAS/Vertex then maybe it's just 'similar'. Always had them down as original kits not copies etc.
Have a word with EP Racing if it's DMAX... anything else you want genuine and not cheap copies like I got for my front bumper lol then speak to Dan @ SRB Power or Albert @ Knight-Racer. They're all decent traders and get you a good price as well
Just some ideas of kits I've liked over the years:
Origin
Yashio Factory Look Plus
BN Sports Blister
Works9 (I have the copy front bumper customised hehe)
