This is a 2.5 degree -1mm front aluminum pivot for all B6 series, T6 series and SC6 series of vehicles. One direct is +2.5 degrees and the other direct is -2.5 degrees. With the 1mm shim attached it equals stock roll center. With it removed it moves your hinge pin 1mm higher resulting in a higher roll center. Use the optional plate kit to get multiple LRC options!
