Thanks bro. Appreciate it. 
Can’t wait to get my S15 in that line up too.
D-Max has no official site from what i’ve seen. Its hard to find information other than what dealers who stock the parts now and people who’ve done the setup. I haven’t had a reply back from NICO/zilvia and so far I’ve only heard of them on S13/S14.
Oh and you cant deny the bandwagon history of coilovers. Regardless, D-Max seem well engineered and the fact that they are popular isn’t based on their introduction to the drift scene or their color scheme but their performance and heritage (D-max makes decent parts)
Which in turn is why I said I will let Mike attest to this. As I do not know half as much about coils as he does. To me, you get what you pay for. Clearly do research. Fuck the colours. Like honestly.
