Well back to the drawing board folks.
Had an encounter last night with a ripped up tire on the highway last night.
Lightweight lip took it like a champ. No damage to that. Bumper clear coat cracked in several spots and took a chunk of paint off. Structurally it survived tho. Going to be able to respray the front bumper this coming fall.
However the diy diffuser didn't survive the encounter. Placed an order for Riegers quad diffuser and $20 for a new toe hook cover. What an expensive night.
