It may make it a little bit easier, but its not something i would consider if doing the shoes tbh. more trouble than its worth.
If you do, its always recommended to get a new nut, they are only a few ££, even from fiat. Some don't but i'd rather not run the risk.
If you make a modified screwdriver tool, like i made (linked recently in another thread), its nice and easy to fit and remove the springs, a couple of seconds to remove, 20 secs tops to refit.
Removing is also very easy if you have mole grips as well, though, they are no good for refitting.
