I had them on my old puma with new shocks etc at the same time. Although supposedly a 30mm drop the car didn't really go much lower because the old stuff was so worn out and compressed on my car.
It did drive very well though and no noticeable negative change. It was just as compliant as before but seem to hold itself better on the road but as I mentioned before I fitted new shocks, top mounts etc at the same time so probably a bit of everything new working together better.
If you can still get them I would recommend them again for sure.
