They have not released a parts list as of yet. However, this shows they are indeed working on it. Unfortunately, for me, this is not the car i originally saw them with, which is a CVT. So im hoping that either their car can easily handle the power or that this car is a CVT as well (maybe they have 2).
Either way its good to see they are working on it.
