Description

These roll-center adjusters are all about giving you the ultimate road holding ability. They are designed to help correct control arm geometry on a lowered vehicle, while improving your wheel camber throughout a hard turn. They are simply the best single handling upgrade available. The new design is made from aircraft grade aluminum, they are strong and light, with a stepped body to remove unneeded material. The RCA kit is 32mm tall, which should allow a significant drop in vehicle height without adverse handling effects.

Lowering a car changes the angle of the control arms, this affects how weight transfers induce body roll, thus by lowering the balljoint to compensate (raising the roll-center), weight transfer will be more predictable, and roll will be minimized. The adjusters offer some of the effects of a stiffer front swaybar, camber plates, and a larger caster angle, all in one product. Unlike the straight RCA kits, clearance for upgraded brake packages is increased, not decreased. Expect the typical vehicle to gain approximately 2 degrees of negative camber, depending on suspension configuration, and carrying more camber into a turn than the use of camber plates would allow.

Because the attachment points are offset by 20mm, there is a corresponding increase in overall track width, the hub will move outboard by approximately 11mm per side. Much like using a wheel spacer, wheel fitment or fender clearance may change, be aware of this.
