So I'm changing out the rear spring isolators and I find this...
It looks like the high and mighty Maximum Motorsports brand rusts too. The factory isolator (rubber cup) fits over that center piece and traps moisture in. The replacement polyurethane ones from StangSuspension are open in the middle.
