Aftermarket K-Members and A-Arms cracking under daily driving?
I'm interested in getting a UMI K-Member. One of my motor mounts is cracked and it gives me a reason to get a better K-Member and mounts. But I've heard that using an aftermarket K-Member for daily driving will eventually crack it? Is that true? I don't understand how that could be, seeing that it is made to handle much more stress than the stock one! Does this also apply to aftermarket A-Arms? What are your experiences and thoughts?
