Seems like a lot of companies are just stopping r&d and not pushing product past prototype. Probably because of the short life span of the car. Blitz never released their widebody kit, they completely sold there car. Hks seems to be non existent with alot of the stuff they had planned...
It's not a refresh. It's just a separate model bit lounder than stock and quieter than the other one, so it passes inspection and noise requirements in japan.
