removing rust from subframes
As I live in NJ and drive my SS daily, I've accumulated a good deal of rust on my subframes. I figure a good project would be to remove the rust and apply some inhibitor/POR/something to slow the rot. Will the front and rear assemblies tolerate being dropped an inch or two so I can get a wire brush in? I'd like to not have to loosen or remove too much to get this done.

The rear subframe can be lowered a couple/few inches without issue - when I replaced my subframe bushings I lowered mine to the point that each of the four bolts were spun in only a few threads, holding the frame up by the bolt heads. Not sure about the front subframe off hand.

I have to drop the front subframe a little to get trans out. I've done it several times without issue. I use jacks to support subframe, loosen bolts allt the way out and then reinstall 3 threads. Then use the jacks to slowely lower evenly. You may have to lower trans mount also to keep it from being stressed.
