Splash Guards / Mud Flaps

[5.0 Probie]

I installed the fronts. Not very happy. Neither of them had the 3M tape in the same position as the other. And once mounted, one of them took me 15-20 minutes using my nails to get rid of the excess tape. In fact, as far as overall usable length goes, the top is inward to the wheel-well 1/2" more than the other-side is that did not require any "Cleanup".

Pretty disappointed overall. Waiting for a warm weekend to try the rears.

Defiantly looking forward to custom fit ones...

That's strange. The fronts on mine were very straightforward. The tape wasn't exactly matching on both sides but they were close enough that I was able to get them on the car no problem. The rears are really easy to align properly.

Splash Guards

I made a short video of some splash guards I created. Better overall view then the close up pics I posted.

Hey man,

I put on the fronts and rears from ZL1Addons. They look good to me and the install was easy. Here I added some pictures. I have 1" spacers all around so these rock guards will be worth the investment since I daily drive this car even through winter (hopefully this is the last winter)! :cheers:

Could you just cover the rear quarter panels with some 3m clear bra, or would that look weird/be ineffective?

this only works to a certain extent. the rocks really fly all over the place. i have the film and i got some chips in a few spots. just installed my zl1 splash guards front and rear and they actually look great. yes the front 3m could be placed better, but i like the way it turned out. the rear looks great too.

like mentioned above i didnt measure and drill. i taped the blocks to the bumper, aligned the guard to the blocks, marked it, then drilled off the car. i drilled all the way through. mounted the blocks, screwed it on, done. taking off the bumper might be a problem later but it should be fine. new 3m tape should let you reapply the blocks later and realigning your holes.

the 3m tape on the front guards, you can kind of see it on the bottom portion as they apply it too far out. the top portion went in too much so it wouldnt have held on to anything. i ripped about 1/4 of the top off and applied new 3m tape i had lying around and it mounts right on the fender like the bottom section. i will fix the 3m tape later when i get new front fenders to hide the 3m a bit better. for now it works well.

It is hard to visualize all that is going on with descriptions of installing the ZL1 flaps, but thanks to everyone posting about them!

As for the 3m tape, do I just have to dry-fit the guard to determine where best to trim off excess tape?

I installed my ZL1addon splash flaps Sunday. They went on pretty easily. I did install the blocks to the quarter panel per the instructions. I put blue painters tape on the outside of the quarter panel where it just bent over to the inside some. I measured straight from the factory push pin to the measurement. Where it lined up with the quarter panel I marked the tape. I put the push pin in the splash flap and the factory hole. With the splash flap in the correct position, I could see the holes in the splash flap lined up right above the marks on the tape. The instructions say put the bottom of the blocks at the marks from the measurements. So it looks like everything was lining up correctly.

I cleaned the inner fender sheet metal with rubbing alcohol per the instructions. Then stuck the locks on the quarter so they were just flush with the quarter. I then put the splash flap up to the car using the factory push pin to locate the flap. This is where I deviated from the instructions. And for very good reason. I used a 1/8 drill bit to drill the lowest hole. Then used the 5/32" drill bit to drill it out. I then used the screw to loosely secure the flap to the lowest block. Then did the same with the next two blocks. The 1/8" drill bit being smaller didn't need really any force to cut into the block. So the double sided tape and my hand were enough to hold the block for drilling without pushing the blocks off the quarter panel. The install was very easy and they look pretty good in my opinion. WAY better than the set I originally purchased from AM and threw away. lol

Can someone post the ZL1 instructions to see or better understand the rear fitment and mounting? I "see" the pics of the rear guards mounted, but want to see the area discussed for mounting...

Thanks!

The instructions are written pretty poorly (so many spelling mistakes that it makes you wonder who wrote it). Anyways I will give a shot at explaining:

1. You have the rear splash guard, three rectangular blocks with adhesive on one side, and three screws per each wheel well.

2. If you look inside of the back of the rear wheel well, you will see that there is a flat section of the bumper not covered by the wheel well line near the edge. The three blocks that you have will attach here with the adhesive, creating a surface for a screw to be placed in.

3. The rear splash guards have four holes: one for the bottom clip that you take out of the liner and then place the guard on and push the clip through to attach the bottom of the guard.

4. Then you line up the top of the guard with your bumper edge to be almost flush. The other three holes on the splash guard are for the screws. You place the blocks right where these holes on the splash guard are such that you can screw the guard to the bumper. Once you line everything up, use something to mark the blocks for them to be drilled. Once that is done, you can screw the guard on.

Just look at the back of the rear wheel well. There is nowhere to put screws or to glued the guards. So you use these blocks with the adhesive to create a place where to screw in the screws. Hope this helps.

I did mine today & hardly looked at the instructions (all text & only 1 picture) preferring the advice from folks who had done the install already. Once you have the flaps and match them to the wheel well, it’s pretty straight forward on how to mount. The fronts are fairly easy, remove the push pins, line up the flap, reinstall the pins and finish off by peeling off the backing tape and pressing the flap into place being careful to align it so its flares neatly to the wheel well at the top.

For the rears, removing the tire is essential. Take out the push pin at the bottom of the wheel well, align the flap and reinstall the push pin. I put painters tape on the outside of the wheel well then rotated the flap to line up where the supplied mounting blocks should go & put a mark on the tape aligned with the predrilled hole on the flap. This gives you the position where the midpoint of the block should be. I then peeled the backing tape and attached the block aligned so the middle of the block was at my marked line on the tape and flush with the perimeter of the wheel well. Note: I found if I recessed the block just slightly, the flap snugged up to the metal edge of the wheel well nicely With the block secured in place I rotated the flap back to mark where to predrill the blocks for the mounting screws. I gave the tape 5 minutes to set up then predrilled using a 5/32 bit and then completed the install using the supplied screws.

They match the trim nicely and look as though they will deflect stones away from the body. I especially like that they are very secure and there is no U-channel showing on the outside of the wheel well. Perhaps a bit pricey for four pieces of plastic + hardware but short of a factory designed product (@ likely 2x the price) it’s the next best thing. Everything lined up nicely and I’m pleased with the end result.

I have a pro-tip for those installing RPI and probably ZL1 flaps on the front. I found with my RPI (and will likely be an issue with ZL1 as it looks like the same design), small pieces of gravel were getting flung up above the curved part of the flap in the wheel well, and because there is enough of a gap between the flap and the wheel well liner, the gravel would sneak down between the flap and the wheel well liner, pushing the flap out from the wheel arch, causing it to bulge essentially.

What I did to fix this was I added some self adhesive foam insulation (the kind you put around windows, doors, etc - closed cell foam with tape attached to the back), cut the height of it so it was a tight fit between the flap and the wheel well liner, so no rocks could sneak down there anymore. I put this foam all down the curved part of the flap, from the edge of the lower part of the curve, up to the top where it meets the wheel arch metal lip. I also added BLACK double sided outdoor mounting tape to the outer edge of the flap, to adhere the flap to the wheel arch (the painted metal). Now the flaps sit flush, and I haven't had them pushing out since I did this. It also gets rid of any bulging from a less than perfect install. You can't see double sided mounting tape unless you really, really look for it, since it's black and fairly thin, it blends right in.

Can you post some pics of your setup?

With the large number of new Mustangs on the road...why hasn't a single manufacturer come out with molded splash guards? My flat guards look like I bought them from WalMart!

I'd like to put in a good word for John at zl1 addons. I contacted him about ordering some replacement hardware since I botched my install and wanted to redo the fitment of mine. I needed two mounting blocks in the rear and two screws. I was willing to buy the parts because it was my fault and he is sending out the new parts for free and even gave me a slight refund for my trouble. Definitely recommend dealing with him if you guys are on the fence about getting these.

It's nice to see someone stand by their products even when they don't have to.

I've had great experience with John also and would highly recommend both him and his products. A very nice guy.
