Not sure if I'm on the right lines here, but are you talking about steering shimmy under very heavy braking? I removed about 85% of it just by changing to mono ball FTAB from bimmerworld. I think the stock bushings deflect a lot. I also run stock brakes, with SRF, PFC-11's all around and RE-71R's. When tires are in their nice operating temp range I get very little lockup even with my foot through the floor.
