    The instructions on the Mopar Splash Guards are retarded.

    I started with the rears. They tell you to remove the rear wheel and to drill out the body plugs. Screw that. If you go in from the back side of the wheel well and just snip the spread back side of the plastic plugs with a wire cutter, they just fall out. You have to drill a hole in the black plastic between two existing holes, but once you have the plugs out you can mark the location using the splash guard and flex the black plastic enough to drill the required hole without removing the wheel. A stubby phillips will get the new bottom screw and a phillips tip from a drill extension tip set will allow you to get the top two screws close to tight with your fingers. I used just he phillips tip from the tip set held in the screw heads with my fingers and a pair of pliers to do the final tightening.

    The fronts are much easier. The one plastic plug you have to remove does not go in flush and will easily pop out without damaging it. The other can be removed with a small socket and ratchet wrench They seem like they take forever to completely unthread and retighten and only seem to go into plastic so be careful not to over tighten on reassembly. They give you four screws and I assume the ones that are coated are the ones they want you to put in the hole they tell you to drill in your nice new painted fender. Screw that too. They will do fine with the three screws without drilling a hole in painted metal.

    I have no clue about the funky plastic pieces that are inside of each splash guard. They don't seem to lock in any way that will keep them from just ending up in the bottom of the splash guard over time or to end up in any specific place they will stay at the time of install. If anyone finds some logic to their purpose and how they fulfill that purpose, I would like to know. If anyone know what the images that look like tiny trash cans on the Mopar diagram represent, I would like to know that too.

    I hope the guys that build these cars at the plant get better directions.

    i used 3m tape on all of them and it made it much more solid.....w/o the tape its floppy....i also didnt drill the hole.

    if you skipped the tape id recommend taking it off, buying some 1/4" stuff and adding it.....it makes a huge difference

    I gotta tell you, if I can install the front and rears anyone can. I did drill a hole in front (tighter fit) and sealed it. As or the rears I followed the instructions above. It's a little tricky tightening the top two bolts, but easily done without taking the wheels off.

    I to drilled the hole. Really wasn't a logical reason not to, as the 2 screws provided are coated to seal and protect the metal.

    This is a guess, but, maybe the plastic pieces are inside the mud flaps to help them keep their shape right after they are made. If you are molding these and then pile them up in a box while they are still warm, the bottom ones would get flattened out.
    The trash can must indicate to throw that part out.

    Glad you got it worked out. Here's some pics I took while I was installing. Just an FYI, you don't have to remove the rear wheels to install the rear splash guards. You can access the plastic rivets from the underside and cut them with a snipping tool. I used a pair of electrical wire stripping pliers. Also, if you go this route make sure to use the 1/4 drill bit and drill from back to front in order to drill through the plastic of the wheel well before removing the plastic rivets. If you have any questions just let me know. I did this in my driveway without any issues.

    Personally, I decided not to tap into the front fender. Although I am considering to have piece of mind. I skipped the top screw and use 3M double side tap instead. It's been proven at 165mph and all good. What most don't know is that when you use the screws provided to tap into the front fender is that it actually releases an anti rust type agent inside as your screw it into the new hole.

    Hope I was of some help. Cheers!

    The loose plastic pieces - my instructions showed throwing them in a trash can. I assume the pieces are left over from manufacturing and they want the customer to dispose of them instead of the manufacturer.

    I drilled and installed screws. I didn't want the splash guards flying off at 200 MPH.:eek:

    As far as the rear install goes for the Challenger Hellcat:
    The rear states to drill/ remove 4 of the plugs - you do not need to remove the lower 2 plugs. Also there is a hole already on the inside of wheel well ...so all you have to do is drill from the inner wheel well where that hole is into the wheel well and your done.

    So for the rear: No need to remove tire...
    1. Remove the top two plugs by clipping off their backs on backside of wheel well.
    2. Drill hole from backside of wheel well through hole that is already present through to wheel well.
    3. Put clips that are provided
    4. Screw in splash guards ...done.

    You can put double sided tape but its overkill....and the areas do not adhere that well because I tried ...3 screws are enough to hold them on securely.


    As far as the front I did drill a hole at the top. This is a Mopar part so honestly they all should have had these installed from the factory standard to stop the rocks from nicking up your paint...removing in the future would be silly. So 1 hole at this location is no big deal and the screws are treated with some anti rust gunk on them so do it right and drill the hole.

    Can someone show pics of the car with these installed? I saw a Challenger with them recently on the road from a distance but couldn't get close enough for a good look. Thanks!
