    You'll have to to excuse me as my background is mostly fox bodies.

    Long story short when having higher engine power and stick tires do we need to reinforce the torque boxes? Where the control arm bolts to the car's frame.

    On foxbodies they would rip,tear out of the car if you ran slicks/drag radial

    On the new cars you just buy the Upper Control Arm Mount.

    BMR Mustang Upper Control Arm Mount - BMR Fabrication - Upper Control Arms - Control Arms - Suspension - 2011-2013 Mustang GT 5.0L

    You can buy lower control arms, but these don't need reinforcing.

    I'm happy with the steeda 3 pt braces that connect the torque boxes with the inner and outer frames. Added weight was negated by removing the rear axle donkey balls.

    You don't see "battle boxes" for these cars like you do with the Foxbody. I have the Steeda 3 point brace. I am sure it helps some. Evolution Performance sells a different version that mounts with the control arm bolt, unlike the Steeda unit.

    I plan to weld the factory seams on the lower mounts and maybe add some plates for reinforcement.

    Stiffler's subframe connectors with a UCA and LCA is all you need.

    These cars still have a lot of flex. These will tie your frame together a lot. Just recently proved they work when they saved my life.
