These RCAs (Roll Center Adjusters, or Bump Steer Spacers as the 510 guys call 'em) are designed to get rid of that pesky bump steer on your lowered vehicle.

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 RCAs on the market. These RCAs will NOT move or become mis-aligned, no matter how hard you drive.

Comes with all new mounting hardware including new Ball Joints and four grade 10.9 bolts and lock washers.

Please be sure to let us know what year your AW11 is. The 1984-->1986  MR2's used 10mm bolts, the 1987 and 1988 used 12mm bolts. We want to make sure we send you the correct hardware.

Choose Small (S) in the drop down menu for the early AW11 or Large (L) for the late model AW11.
