Not sure what you're pushing for....or against....here. There's already manufacturers. What are you wanting to accomplish or what do you want others to create?
Not pushing against anything.... i know a few phantom customers that have converted their flat karts, and do very well in the lower hp classes. And as a long time phantom customer, it would be nice to have a phantom for the higher hp open classes.
I have a Coyote/QRC conversion kart that uses 4 QRC front receivers to mount the QRC cage on the Coyote LTO chassis. No reason that couldn't be done for a PRC chassis... I'd sell my conversion kit for reasonable price if someone's looking.... ~Ted
