I did the control arm brace on my '91 metro EV and it made a major improvement in how my metro handles. The car felt like the front tires were going out of track when pushed hard in a corner without it. Lucky, it's a California car with no rust. The biggest improvement I have done so far for efficiency is a full belly pan out of 1/8" delrin sheet. It lowered the Amp draw 22% at 65mph, from 230 to 180 on flat ground.
