When I put an R31 Skyline in my Bluey with Nolathane bushes it made a hell of a difference.
With the old bar, if you got sideways in the wet, you could find yourself swaying back and forth uncontrollably for the next 200m down the road. It lent over a fair bit on corners too.
With the new bar, 26mm instead of the old 21mm, it stands upright. I do agree, when it's wet I still find myself sliding out when cruising around, however when it does kick out, all you need to do is counter-steer a bit to keep you going and you're fine.
If anything, I found it a safety benefit, best $100 I ever spent on the car to this day. And I've bought a CA18, strut brace, and lots of silly parts!
