This was to correct a defect on some cars sold in 2009. The lower tubes were raised to the proper position in the picture. The upper mounts were redesigned and raised to accept a longer shock. This corrected bump steer, roll center and shock travel issues.

One option for some cars starting around vin 411 that may have had a design problem. The lower A Arm mount was moved up and new higher shock mount was made. This corrected bump steer and roll center flaws. It also gave the suspension a greater travel. Instructions available upon request.
