Visible Differences Betwwen 2530 V1 And V2?

[Sayajin]

Hey guys. I know that recently HKS released a new version of the 2530's that have more potential power. I am in the process of possibly buying a set of 2530's from a friend however I want to make sure that they are the second version before I do.

If anyone could tell me any visual differences or markings that I can look for to ensure that these are indeed V2 ones that I am buying and not V1 then I would greatly appreciate it! Also please bear in mind that I do not have a V1 and V2 sitting side by side to directly compare, so please dont say bigger wheel or something like that. Thanks for all the help guys.
