A Bilstein performance strut assembly ... The Best!
Upon initial build of the car, I did not attach the upper stabilizer bar because it interferred with the mounting plates for the DC/DC converter, the main contactor and the throttle pot. I trimmed down the mounting plates and now the bar fits. (I put a lot of work into getting a great paint job on the bar.)
Here is a pix of the strut assembly installed in the right side of the car. The springs are not stock, but custom wound units designed to handle the added battery weight AND lower the car about 1-1/2" (38 mm)
