Thanks!
If you don't plan on driving through 2" deep flooded puddles of standing water, they would probably cool better without the disk sheilds. You could try to use the shield to support brake ducts, but it's pretty flimsy.
I have a circle track general fit brake duct adapter. But I don't have 3" neoprene ductings ($$$). I did score 8' of 2" for like $20. Close but no cigar.
