It is true that the 40's are closer to stock size than the 45's. For me personally, similar to the OP, I had a great deal in front of me a couple of years ago and couldn't pass it up. And in my case, I am not lowered at all, so the extra half-inch of sidewall actually helps to fill the wheel wells better than the 40's do. I will say that it was a snug fit for me and I shaved down the bolts of the knuckles a bit for peace of mind. If it's a high performance tire that doesn't swell at high speeds, there shouldn't be any concern for it hitting that knuckle bolt. I've gone a bit over 140 (on W rated / 168mph tires) and had no issues. No rubbing and full range of turning as well.
To the OP, my 275/45/20s are mounted on Konig Rolf Blix 1 - I actually don't know the specs of the wheel offhand, so I don't know how the offset and everything else would compare to the SRT Design wheel, nor do I know the differences in the suspensions. If it has an SRT suspension, I do know the knuckles have a much more aggressive angle to them, which should give you even more inside room. But if you have the same suspension as my C and the same offset/width as my wheels, then you are fine as long as you don't exceed the speed rating.
Still want to know where the deal is!?!?
