we made these for a 95 subaru impreza but these steps are universal for any car!
tools you need:
two semi truck thick plastic mud flaps - about $10 each (from peterbilt shop in WA)
ratchet and socket set
skil saw or rotory dremel tool
pencil or pen to mark you lines
can of spray paint or similar (for rounding off the edges)
Step 1: Measuring and Marking
first remove the front mud flap and put it on top of the semi flap. make sure the flat side is facing down.
measure how much extra length you want and put the outside edge of your stock mud flap on that line, so you have the extra 1" of material, mark your lines. and trace the outline of the mud flap: this is where the t-square comes in handy!
dont forget to mark the mounting holes from the original mud flap
Step 2: Cutting
take your time! we left a little extra material on the edge so we could sand it down to look smooth.
when your done cutting it, lay the original mud flap on top of the new one to make sure your cuts, and measurements are good!
Step 3: Test Fit
(optional) also we measured and marked the top edge of the flap to cut the notch to look like armor mud flaps.
Step 4: Finishing the First Mud Flap
use a can of spray paint to mark the bottom edge's to round them off for a better look.
then cut the top edge off
Step 5: Finish
at this point fix anything you dont like.
now use sand paper to smooth the edges for a real nice look.
now that you are finished with one of the front mudflaps, put it ontop of the truck mud flap and trace it out, cut, sand and finish it off for the other side. repeat these steps for the rear mud flaps and in under an hour and only $20 you have $150 pair of rally mud flaps! enjoy and go have some fun!
