Support bars for Subframe

[TheRoaringEagle]

Was wondering if there are any companies making a bolt-in/weld-in pair of support bars for a stock Camaro subframe, similiar to what martz chassis has for their racing subframe kits?

Also, is their any drawback with them? I'm not running my inner fenderwells for the moment, and want to compensate for the structural loss and eventually make some homemade fenderwells, thanks!
