Roll Center Adapter I think, they relocate the control arm, to give you back suspension travel and fix your camber. Also takes some of the stress off the front suspension components.

They make them in .5" through 1" so if you car is lowered at least .5" you would get that .5" of suspension travel back.

I think you are confusing this with something else, you don't need RCA's to do a brake upgrade.

You have two basic options..

1. RCA
2. Trim off some of the tie rod bolt


These are the two more common methods for LS400 upgrades
