Chasis bracing, what works?

[LaserSVT]

I know from past experience that Mustangs NEED full length sub frame connectors and the ones for the S197 chasis look pretty substantial. The problem is I see now they also have a nice 3-point torque box brace avaliable too. In the ads it says on the verts the sub frame connectors have to be removed though.
Does that mean you cant purchase FLSFCs AND torque box braces for the new cars? Is there a different brace to be had? I figured with the high HP numbers they can get and how much the new GT500s have that you would really want to reinforce that particular weak point but also want the FLSFCs.

So am I wrong or can you not use these two parts together?

1st off these are marketing scams, Unless you have over 600RWHP chassis braces like these are not needed, the S-197 cars are not as flimsy as the Fox or SN-95 chassis Mustangs. A good strut tower brace maybe even the Steeda shock tower brace will do for street torsional flex, you also should looks into the tranny brace for CHE.

i like the box ones like the red ones you posted, think they might be bmrs.

i definitely plan on getting them on my car. they can't hurt.

i wish they made them like they do for the sn95s and foxes. they got the maximum motorsports like the ones my brother has on my old one, that are full length and also extended about a foot or so onto the existing subframe.
