Besides the correct answer above you could ditch weight.
Toss....windshield, seats (use a light weight race seat for driver or a milk crate), spare tire, toss the front and rear bumpers, remove the skid plate replace with a skid bar, cut holes and dimple die the frame. Remove front and rear track bars, steering stabilizer, sway bar. Remove the gas tank skid and replace with strap steel or twine if your cheap. Lower the spring lift to 2.5 inch lift, cut body to allow for tire size. Replace roll bar with a chromoly roll bar, or live dangerous and use aluminum. Replace hood with a lexan version. Mold a new light weight grill out of carbon fiber. Throw out the dash and just zip tie and glue gauges in place or toss gauges you don't need them. Only put 3 gallons of gas in the tank at a time. Replace the gas gauge, you will need that. Toss the tail gate, no need for one because there is nothing to keep in, might as well toss the doors as well. Replace the headlights and tail lights with stickers and only run during the day (keep lights for easy replacement during inspection).
So yeah, simple answer is not really, not so simple answer was kinda fun though.
