    BACKGROUND
    Since owning the CTR this year, I've been on a lookout for a product to protect the paint around my wheels from splashing rocks and debris. As some of you owners may know, road noise is ridiculously noticeable. It stresses me out when I hear something that sounds like something just chipped/cratered into my paint.

    I know Rally Armor finally makes one for our cars, but I really don't think the 'rally' flappy look matches the look of the CTR, but to each their own. I found a company in San Diego that makes rock guard pieces for Camaros, Mustangs, Challengers, etc. and been trying to reach them about making one, but that didn't pan out. There is a fabricator here in the forum that makes a carbon fiber version that looks really nice. Unfortunately the maker doesn't have any plan to make lower cost, non-CF pieces at this time of writing. Also, it is currently more expensive than RA's, granted that it's a material that apparently is more sought after by most.

    For me, I define my needs for a set of rock guards (no longer calling them mud flaps from this point on) that are:
    - Minimalistic, looking as close to Honda would provide as possible.
    - Low cost and maintenance. Something that you won't cry about if the piece breaks going over bumps, during auto-cross, etc.
    - Material that matches the OEM plastic. Existing OEM screws and locations. No drilling. I know people are scared of that (me too).

    R&D - INITIAL DESIGN AND RESEARCHING
    There are a few people in this forum that have made their own, so there are definitely inspirations to gather from; I see these as a small taste of owners' desired preference towards the design and function. I did many measurements on my own car using 11x17 papers and cardboard cutouts; making several iterations that would mount securely onto the wheel arch. I determine that >15" is a decent amount of surface area to cover. It's about 2/3 the height of the OEM wheels. The flair is about 1" over an existing fastener. The flap I call 'the hanging ear-lobe' is about 1", which shouldn't catch on to anything (I believe the flap for our front spoiler is still lower to the ground than this) I secure the rock guards with the OEM screws. Again, this is something that I highly desire. I don't like bracket systems or anything that require drilling additional holes.
    - For the front arches, the rock guard piece extends over 3 OEM screw locations and 1 OEM fastener at the very top. I converted the fastener location with an adapter and use approximately the same OEM screw from AutoZone to better secure the piece.

    - For the rear arches, there is 1 screw that secures the rear bumper and 1 further up that secures the rear fender. Since I only have 1 screw location to reasonably work with, I additionally secure my rock guard piece with automotive molding tape. The result is as shown. My testing so far over 1 week is holding on pretty well. It's been raining a lot here since I put them on and it doesn't look like they're peeling.

    PUDDLE TEST TODAY (05/08/19)
    Also, if any others are wondering/have concerns about how the rear guards hold up with only 1 screw + molding tape holding them, I drove through massive side puddles today during heavy rain and they weren't moving/detaching. We're talking about the puddle that activate your traction control when you go through it too fast.

    I think it helps for the rear to have a balance protrusion going outward facing and inward facing towards the wheel well.


    FURTHER R&D
    I would like the ability for my rock guards to slide horizontally. I think this is best to give flexibility in making the alignment look just right to my taste between the left and the right side of the car. Making precision screw holes for 1 side of the car, unfortunately doesn't mean it looks 100% as correct on the other side; definitely something that has to be eyeballed.

    The bonus factor of having the rock guards to slide horizontally is that I can adjust how much flair I want. Do I want more protection? Let's extend/pull them out a bit. Do I want a minimalistic look? Push them inward.

    Some small tweaks here and there...

    PROPOSAL
    Now to the main reason for this post. With there being little market to this product for the CTR, I would like to enter the arena of being a provider for this product. Working on this project had been a fun and exciting side project. Also, with enough resources and interest from fellow owners, I am committed to be able to provide my set of rock guards to the 25,000 CTRs out there (a stretch, I know). I do want to start small, this is my first endevour into this. I dream big but I think it's important for me to stay small (for now) in order to maintain confidence in what I can and cannot do/provide.

    What I am proposing is to make a full set of adjustable CTR Rock Guards based on what I have made. I wanted to do this based on your input and number of interest. I want to start with a workable, small volume/request that I can provide to this forum's members, something managable. I would say 10 is a realistic goal to start?

    Depending on how this post is received via comments, I can start a Google Form on the next step. I haven't really give much thought to the price or anything else; just that I want to sell them as a full set. I'm too anxious about whether this is gonna take off for now or not.

    Q&A
    Q: Why not just provide a method/template on how you make the rock guards?
    A: This is something that I've thought about as frustration on getting another to build this product never came into fruition. My thought is that there are people out there that demands for it but don't have the time nor the resources to make their own. I pretty much just completed that process and can only see myself as the shortcut to the time and resource that YOU don't/may not have. I don't want people to necessary throw their money away, but at the same time, I understand that there is a need for something and that need can be fulfilled in a timely manner, with little to no logistics on your part. Everyone can make pizza if they want to, but would you want to? The recipes are out there, no?

    Q: Why not just do PPF on the car?
    A: I'll let the masses answer this. PPF isn't exactly cheap. Although I did do it on my full front out of stress of daily driving, these high impact areas are going to take a beating regardless.

    RANDOM PICS
    Better 'beauty' shots will be taken soon. It's been raining left and right here.

    Hey! I’ve totally been looking for something that protects but isn’t very noticeable. I don’t really like the look of RallyArmor mudflaps either. Depending on price, I’d totally be interested. I’ve been thinking about getting ZL1 Addons rock guards but they’re around 80$ for the set. I might as well get the universal rally armor ones and cut them out. But I’ve been very hesitant. Let me know what you end up deciding!

    RA front flaps not much different than your mock up. Even with a wider wheel, lower offset, and much more poke, they’re super protective and low profile. Also side slotted so you can increase or decrease side protrusion.

    I don’t run the rears because of your reasons, but also because the car is front wheel drive, so back wheels don’t throw debris. Cheap, easy, painless. YMMV.

    All the good looking carbon fiber rock guards available are too small to offer the protection my car needs. It’s unfortunate but when it comes to rock guards, size & cosmetic appearance is always working against each other.

    we only have two options for rock/mud protection so good job making your own.

    i have one auto-x season on my old skoo fab carbon fiber rock guards and have ZERO rock chips...
    here is what i'm up against in our loose asphalt ridden paddock and grid at aloha stadium :D

    Thanks for your responses, guys! :)

    That's exactly what my experience has been. I had asked them to make one for our CTR but asked for the price point of the Accord that they made already. Looking at what they charge + the rather costly shipping charge, I think that was part of my reasoning to bail out with working with them.


    Hi, thanks for making the comparison with RA, it's a much needed input for those who might be interested. I believe with mine, the most minimal protrusion that RA provides will the maximum of mine. My version would be able to tucked in more to reach the minimalist approach I'm going for. I'm thinking about .5" of flexibility to slide in and out.

    As for the need of the rear to be protected... I'll leave it to the consensus when I do the Google Form survey. Thank you again for that insight.


    That is true and hopefully I can meet somewhere in the middle and leave it up to the users. I can at least assure the height of coverage. Like I mention in the original post, my rock guards should cover 2/3 the wheel height from the ground.


    To be determined :) Thank you for your interested. I'll try and be reasonable. As for quality, mine is not like RA's. The type of plastic I use is close to what is used in standard automotive industry. Think of those plastic cutting mats for your kitchen but thicker (0.3"), slightly more textured, and black. It's flexible enough to contour the wheel arch and sticky enough for molding tape.


    Hey Bouford, thanks! Nice seeing you here on my own thread lol. I know you rock the CF one by oldskoolfab, so it's cool you took notice. I definitely took some inspiration of the minimalist approach that he had done to make his :). I don't think I'll be auto-crossing my R any time soon, but if people really want to test mine against intense driving, they can let me know here :) I'm sure they'll hold up though. I don't see a reason why they wouldn't.

    I'll be interested once I get new wheels. I'm not a fan of the RA, way too flappy looking for me. I'm definitely a minimalist when it comes to rock guards/mud flaps. As of now the ones I have my eyes on are from ZL1 and are for a Focus RS. You look like you have a great product going and look forward to hearing more about it!

    Interested! Basically checked all the boxes in what I’m looking for: not overly big, minimal, non-cf.

    Basically closer to an OEM option we never got.
