This is my favorite brace for any miata. Extremely light weight (made out of aluminum) it provides exceptional increase in the front end stiffness. The first time I installed a brace in my miata and went through my favorite twists I almost crash since the car was so eager to turn in! This one has been further modified to provide support for the brake booster - which in JDM cars is at the other side.
If you can't fix it with a hammer, you've got an electrical problem
