Rally car DIY constructors...mud flap material

It's time to start finishing my Porsche 911 rally tribute build. What material do you use for mud flaps? Where is it available? I want to use black, not white. Any photographs of your own creation or suggestions on construction appreciated.

Thanks in advance

I've used ABS plastic, flexible cutting mats, "urethane" Rally Armor knockoffs, and rubber. The harder materials will crack when it gets cold and they get pelted with rocks, the softer ones are easy to rip off by accident. My recommendation would be to just get universal rubber ones, trim them to fit, and use large washers or large headed rivets to mount them.

My current rubber ones, $15/pr on Amazon:

Thanks...was hopping you would weigh in. Love your build.

Thanks! By my count I've killed upwards of ten mudflaps at this point so I felt qualified to comment

I did also have a set of the RallyArmor Basic flaps that held up fine on a rallycross car, if you wanted to spend a little more money and like the look of their stuff- I still think they would end up destroyed on a stage rally car, so I prefer to use cheaper stuff since it's a consumable at that point.

I'm only pushing about 250 hp with 205 70 15 tires so maybe whatever I come up with will survive. I doubt there's a rally cross within 700 miles of me so I won't be competing regularly. But I do have a lot of country dirt roads and levies to run around on in Mississippi period LOL

I've built a set from a $20 semi truck mudflap. They were pretty durable, but I only used the car for Rallycross, not stage rally.

I made mine out of a couple of these poly truck mud flaps. Link Depending on how large of mud flaps you're making, one might be sufficient. I went quite large with mine due to FWD.

I hear conveyor belt material works great.

and if you have company with a big fleet or a heavy truck shop near by you can probably get some for free that have been ripped off of trucks and cant be used again, they usually end up just throwing them away

I had a set of the cheap Rally Armor flaps on my Hyundai Acc(id)ent that held up surprisingly well throughout 100,000 of the worst abuse you can imagine. That would probably be the cheap & easy solution for you.

I've got a set of flaps that were supplied by rallylights.com. It's a thick, flexible plastic, about an order of magnitude more robust than a cutting board. They survived two Targa Newfoundlands and a bunch of track days.

polyurethane mud flaps from rallylights are going to be better than all the other suggestions by far. I bought mine years ago: http://www.rallylights.com/mfmat-mud-flap-material-black-or-red-per-square-foot.htmlhttp://www.rallylights.com/mfmat-mud-flap-material-black-or-red-per-square-foot.html

don't bother with rally armor or cutting boards. the trick with the flaps is that you need something like a leather punch or a small tube sharpened on one side to make the holes, otherwise they can be cut with sharp shears.

We have the Rally Armor "SUV size" basics on the e30, and the've held up for 5 years of rallycross and what...3 rallies now with no sign of any problems. But we don't shoot gravel as hard as you do ;)

Nice to see you on here, Kevin

You can add another 18 months and 15k miles to these flaps and they're still holding up fine. Though, my commute is on much friendlier roads than Pete's was. Still haven't made a rally cross with 'em. The group running at the Badlands died right as I bought the car from him. So, closest now is Western Ohio or Detroit regions.

1 semi-truck mudflap = 4 rally car mudflaps.
