Question about mud flaps, specifically Rokblokz.

[F26_Raider]

I recently installed Rokblokz on my Mach 1 and I'm very happy with how they turned out. Something I didn't think about beforehand: would these have any sort of negative impact on the aerodynamics of the car? Anyone who's installed flaps on their mustang, have you seen any noticeable difference in handling, MPG, or even track times?

Handling and MPG, no difference at all. Haven’t been on track but I assume no measurable difference there either. I have Rokblokz as well

Fantastic! Great to know. How have they been holding up?

They’re holding up really well. Been on the car for almost 4 years now and it’s my daily. No complaints here.

Mine are doing well too

I've had mine on since mid 2023 with no problems. Over time they may shift a little but they can easily be moved back into place. Don't overtighten the fasteners.

I’ve been using them for about 1.5 years and no problems. I hated the silver screw heads so I used some paint pen that is for touching up anodized aluminum on guns and blacked them over… you cant even see them now.

I use slip on's. I have not lost any while driving on the street or freeway (seven years). Back when I track the car I always removed them on track days. I cant remember the brand.

Say, I noticed the logo on your rear flaps are facing outward rather than inward of the wheel well. Are they supposed to be like that? I'm asking because I ended up doing the same and am considering reversing them. It also seems like the texture on the other side better matches the OEM trim.

They come flat and are not side specific so I don't see why you couldn't flip them around to place the logo inside. The inside is very smooth.

Mine have been on for about 3 years now and the only issue l’ve had is the front ones developed a gap which would catch small pebbles between the fender and flap. I used double sided tape and problem solved.

Awesome, that turned out

I ended up flipping them around and you were right. No issues at all. Aesthetically, I think it looks better this way.

I had them on my truck...and that brick was flying with them at over 140mph a few times haha. I had the XL version on my truck to keep rocks/mud etc and stuff from hitting the truck.
