I will have to go with Pierre with this one too. A racer friend of my dads told me the same thing about a tourquey motor distorting the strut towers.
I dont know weather my car will have any problems with it but I have made one up just incase "read 'showpony'".
It is made from two Falcon torneu? cover holdy upy things, so it has a nice curve to it. Ha, as soon as my engine bay starts to twist, my welds will probably all give way
