I have an 06 V6 stick coupe. Has anybody bolted on the the conv. subframe to stiffen up the car?

 

was actually looking to see if anyone had welded in a subframe in a convertable with pictures so i can see what it all involves. looking to stiffen up the o' girl so i can corner and not feel like im riding ins a wet washcloth.
