Anything that strengthens the front end, minimises flex and distortion of the strut mount areas and helps against the common problem of fatigue and flex cracking can't be a bad thing. I mean, if it does nothing else, you're probably still way ahead than if you didn't, even gramps in his daily.
I have a stock holden brace slapped onto a base model VZ wagon with rolly-polly suspension, I also have an aftermarket fitted to a VX R8 with fairly upgraded suspension. Both are bolt-on and walk away, remove just as easily and no harm done. But simply rolling through a roundabout with a few quick wheel turns does feel firmer, how much, hard to say, so it's a very cheap and simple upgrade with some benefits.
But they don't add too much HP, so no stickers required.
