K-Member / Rack & Pinion Steering Suggestions

The answer about the lower control arm mount is in the experience of the people who actually bought the kit and are using it.
I have searched and searched for any negativity about build quality and component failures of the RMS System . I couldn't find any. Same for HDK Systems.
For what its worth, I have over 5000 miles of street driving on mine and its perfect. No issues whatsoever.

Not saying I expect a failure, only a concern for instability. And it's just a curiosity, it's not like I've done design calcs on it or anything. I'd hope someone has though.

Just seems like an area where by nature it starts from a weak point and you spend time/effort/money/materials to shore it up. Just a point of concern for me.

Glad it has been good for you. Nothing worse than doing something big and then being disappointed.
