Bump Steer Spacers ( Roll Center Adjusters RCA's) for the Datsun 510 when using the 280ZX struts only!
These are to correct your geometry on lowered cars. We run these on street and race cars with great results. They mount inbetween the strut assembly and the steering knuckle. We also sell billet fully adjustable lower control arms with TC rods, Big Brake kits to match.
Eliminate bump steer on your lowered 510/280zx. We also have them for the 240Z 260Z and 280Z. The alignment sleeves are solid milled into the unit, so they will not get lost or come off. We also added a larger alignment ring for the center of the unit, to provide even more shear protection than other RCA's on the market. These RCA's will NOT move or become mis aligned, no matter how hard you drive. Comes with 2 mounts and all mounting hardware (four new grade 8 bolts and lock washers)
