2019 Challenger Hellcat Redeye Widebody
I bought the ZL1 deluxe standard diffuser and I like it OK. It does come attached to a aluminum belly pan that goes all the way forward to the crossmember behind the differential. You have to do some modification if you have a diff brace which I did. My only real complaint is that I wish the fins were a little shorter and contoured to match the contour of the underside of the bumper and black skirt back there. I have thought many times about removing it and contouring the fins better myself but it would be a big PITA. I contacted ZL1 and asked if they would make me a custom diffuser to match what I wanted and was willing to pay whatever they felt was fair to do so but they declined. I guess they have enough work as it is. I will say this, it definitely decreased the amount of road wash/crap that ends up on your rear bumper and trunk so it does work as it was designed to.
