Anvil inner fenders?

[HMA]

I am looking to swap my stock sub up with the DSE hydrafrom sub and was considering swapping to the Anvil inners at the same time. Just wanted to see if they solve the clearance issue of rubbing on the outside edge of the inners. I know that they are supposed to be wider and taller than stock, is the clearance enough though? I am going to run a 275/35/18 in the front with 6.125" BS on a 9" rim. My current setup running a 245/40/18 with 5" BS on a 8" rim and barely rubs the inner fender on the outside edge as it curves up. If Anvil is not the way to go looking for recommendations. Is it worth modifying the original steel inners instead? Thanks for the help.
