While SD_Engr is totally right (phone call is best) I did get an e-mail response from Mike. It reads:
"we will not be offering new sizing for now, we might do another round of group buy for existing sizes once we have fulfilled all existing orders. If there are enough interest for new offset we might consider. Overall it will be at least 4-5 months until we see more wheels arrive".
So not gonna happen. It's understandable from their position and you're right
@ppower they probably don't want to be stuck with surplus stock (I doubt they'd have ANY trouble moving a few surplus orders, but what do I know). Anyway I paid my balance and will post some pics once installed.
If they end up offering +25 down the road I might just sell these and buy another set!
