I don't know how many of you guys have heard about this (I stumbled across it on FourEyedPride), but MarvoMont is at it again apparently- this time with 18" 10 Hole wheels. 17" are supposed to follow, and then a new version of the current PonyR, and there is talk about a 17" turbine as well. Pics (computer renderings) and links below.
