Either I could purchase a midpipe which would make my car lighter and increase power, or I could spend money on Rally Armor M-Spec universal flaps which add weight and cone-catching goodness. Yup, I picked option two! If you ever add these to your Miata, you want the UR+ or M-Spec options because they’re longer (more mounting points up high), you want U-clips and very large washers to attach them to both the “loose” fender/bumper and the “secure” body underneath, you absolutely want to measure twice before drilling, and you need to cut the rears a touch to clear the inner wheel well. Also, unlike the front which is perfectly symmetrical, the inbound rear mounting options are slightly different.
