A friend of ours came in the shop with some rear traction issue, apparently his rs4 tires couldn’t handle his supercharged engine.
We came up with a full package that corrects the lateral rollcenter by raising the spindle 1” directly in the knuckle. In addition, we changed the lower pivot design to have a separate ball joint and toe link. The toe link is used for toe adjustments and since the two ball joints are in line, the camber isn’t affected as much when adjusting toe. The toe gain (positive or negative) can also be adjusted easily by simply modifying the spacer stack on the toe adjuster at knuckle.
The new knuckle was dropped by 1”, you will have to supply a new OEM wheel bearing.
