I used ABS on my rear shock tower to make an intake/scoop. It is very strong but i had to brace the whole thing with a metal bar to prevent the 90 degree bend in the abs from bending. I'll post some pictures...
By the way your welcome I'm glad i could help. ABS is sometimes flimsy you can probably make a brace out of abs if you wanted, you can use a wood file and some superglue with the abs. Make a vertical part inside the bend of the abs brackets that you just made. Just remember that if need be you can use a heat gun or a lighter or even a blow torch to add a little heat to ABS and bend it.
