I still have these parts if some wants them.
Here are the extra parts I have for trade or sale.
Parts from the STR-4 PRO
one machined cam motor mount $20 + shipping
one carbon fiber chassis plate $30 + shipping
one carbon fiber front steering plate $15 + shipping
these are the same as what is pictured on my car.
I also have one of my camless motor mounts to trade for a long carbon fiber top plate.
