I started to install my flying Miata butterfly brace and frame rails and quickly ran into a problem.
I know my Miata was previously slammed and it appears that it has also bee bottomed out hard on a speed bump. The subframe rails a pretty crushed on both sides in the same spot. They are now too wide at this point for the brace to fit around them.
I have tried beating them skinny with assorted hammers and wood and metal blocks. I have tried jacking the frame rail around the bludge. I have tried lowering the car onto the frame rails with a woodblock under them.
I have concluded that something must be shaved. I am thinking I will notch the fm brace because I don't want to weaken the cars subframe any further.
I appreciate any feed back and advise. I am also reaching out to flying Miata for advise.
