Advantages of aftermarket upper:lower control arms

That’s actually not a good way to execute that cut.

A smooth cut with a radius like I showed is the way to do it. The UCA is tubular anyway, the square corner does not improve the clearance any but it does provide a place for a crack to start.

Thanks for the input. I will round out the bottom of the cut, since I am still at that stage of the build. However, there is still a slight return at the top of the cut. I really didn't have to cut much at the top. My control arm support looked somewhat different from the one shown in your photo.
