Ive already been in contact for a set of 17/18 but also found 2 seperate 18 and 2 seperate 19 but the 18/19 were in different colors so I planned on powdercoating to match. These wheels are classic and look great, just for my own preference have always preferred the 18/19 look on the nsx although 17/18 with spokes that extend do look great as well.
If you start finding them in random sizes, pick them up! Best investment in these uncertain financial times. haha.
For some reason, these actually look quite good in 18/19, especially on Mike's NSX. Most other 18/19 (no-lip) advan setups look way too big. I don't know why this works, but it just does. I however prefer the 17/18 for my own use. I'll get pics up soon to help you decide.
