That's right, they don't allow as much roll in the axle, but they are a lot better than trashed bushings, and I've had them sitting in my parts stash for years, so on they go.
I'll probably run Kaplhenke trailing arm bushings, just need to suck it up about the cost.
I can tell you that the car's handling has improved dramatically, the rear end is much tighter. I threw it into corners hard to see how much roll it would take to hop a wheel, and I was able to do it, but only under very hard cornering, I was at the grip limit of my tyres anyway.
