I've got B&G's with a set of spring blockers on my car and don't normally have issues.

If you're going to lower though I'd suggest the Eibachs. Had a friend with them on his car without spring blockers and he didn't have any issues. The car actually rode really nicely too. I Kinda wish I had gone with the Eibachs.

I tried a set of Vogtlands at one point and didn't like them at all. Car rode too high and soft for my tastes.
