First pic: front of car. My finger points to the end of the bumper and start of factory plastic engine guard? This is what I slid the underbody on top of. There are many holes for you to insert wire to tie to your coroplast. (Poke hole in coroplast)


Second pic: another view of front of car/underbody.


Third pic: rear of underbody. Attached via wire to exhaust heat shield holes.



Fourth pic: middle rear underbody. Note the cut out section for exhaust space.
Also, the side of the coroplast provides ample space (6"-8") for the control arms and suspension.

Hey there, Fitness. Nice work. I am interested in simple/cheap mods to get better gas mileage. Thanks for putting up more pics.

Would you consider joining us in the Fuel Economy Log section so we can see what kind of mileage you are getting with this and future mods?
