The ball joint cups are repositioned for optimal performance allowing a 30 percent improvement in wheel travel. The FOX upper control arms are finished in a durable black powdercoat and include a FOX branded billet aluminum ball joint dust cap. The control arms come fully assembled for easy install right out of the box. To compliment the uppers, the new lower control arms are built from high strength steel, fully boxed with internally gusseted.
As it sits today, nothing underneath the car remains untouched: complimenting the H&R coilovers and sway bars, all of the suspension's components and bushings have been replaced. Powerflex black race bushings replace every factory counterpart, and aluminum E31 lower control arms are paired with new factory E28 upper control arms, tie rods, steering components, and more. Fresh bearings, hubs, and hardware keep things rolling smoothly. The rear subframe was modified for camber and toe adjustment, and mounted to it is an E30 M3 4.10 limited-slip differential. Adjustable sway bar links front and rear allow for fine-tuning, as do adjustable camber/caster plates at the front end. E34 540i brakes add lots of stopping power to the front end, and E32 750iL rear brakes keep things balanced.
