Um...Why not just try the second stage

As for the weight, well the old saying of look for ounces in many places instead of concentrating on pounds in a couple. Cut off any extra bolt sticking out from nuts, extra wiring, plastic headlights, bumper brackets, eliminate anything that is not needed. I mean how many bolts to stock steel fender really need to be held on? Plenty of light brakes out there. Aluminum bolts are another way. Just look at EVERYTHING on the car....
