So you are Gona sell a mid travel kit to someone before testing it yourselves? Sure it may make sense on paper but actually testing it is way different. Doesn't seem safe
I am sure it will be plenty strong, I have seen parts from them before and they arent unsafe by any means, its the driver in the end that determines safety, lol. Anything can be broken if your a douchenozzel.
The products I have seen were built very beefy and failure wasnt something that came to mind when seeing them, look at the other products before you start pointing the finger to get an idea of what type of work comes out of there.
