the imca spec upper from speedway is a strong piece. i hit two uke tires in a row i hit the first one and it pulled me into the second one, i lost a spindle but thet was it the control arm is fine, and i have never had a stock one survive a hit like thta before even braced

yeah but my question is do you want the arm to give or do you think theframeis gonna give if you have the arms over braced?

What can you do with stock upper control arms ? We have to run stock, no tubular a frames.

if it is a stock gm upper to renforce it you need to weld a good size piece of rebar in the two channels on side weld all the way down the piece of rebar on both sides

1/2 inch square or round tube welded into the channels on the A-frames.
You want the A-frames to give up before you bend the frame mounts. Is your mount braced with a gusset? I still think an A-frame is cheaper than a spindle and a LOT easier to change.
