I did something similar with clear plastic, but plexi works good too.
Is it just me or does the ZJ have the only good cooling system? I've never seen the needle get to the 210 degree mark. It usually hangs around between 180-190.
One thing that gets annoying is when you take it to autozone or something to get something and the guys ask why theres plastic over your grille. Then you say to heat the engine faster (less time in open loop) and create less drag. Then they ask whether or not you need a new thermostat and if yours is faulty
OH!:
Maybe try using plexy over the headlight slots, they seem to be mini-parachutes
Removed the roof racks yet? (if there is any)
