Bringing them back from DISC - Verus rear diffuser

[Dialcaliper]

I don’t but it’s super easy. Just remove the rear bumper cover and use a flapper to sand off the plastic from the back until the honeycomb is open. There’s pics in my build page. It’s way easier than the grill. View attachment 65205

How does the lower bumper seem structurally after you sanded out the grille? Does it still hold its shape well, or does it feel flimsy?

Mine is actually better since packed air isn’t pulling at the lower two plastic tabs. Multiple runs over 130mph and zero issues.

Does this really help much? Looks super cool and I'm wanting to do it soon! @Woods247 said higher top speeds. Could you explain more if it's effectiveness?

Air gets packed behind the bumper cover at high track speeds. Actually it’s probably effective at any speed over 45mph. I definitely saw a speed increase by a few mph at the top of 5th gear on track at Road Atlanta. After adding the Verus diffuser (to my already opened rear bumper) I saw no gains anywhere. Others may experience different results but in my real-world tests it showed no gains. The car needs a flat floor and maybe a tiny flap to kick the air over the rear torsion beam and sway bar to make a rear diffuser effective. I’m surprised Verus didn’t account for the OEM floor, rear beam and swaybar in their computer models.

Ok, now I can say it’s a net positive because I can see my shiny Mountune.
